To Decant or Not to Decant

duckhorn decanter

To decant or not to decant, that is the question! At its most basic to decant simply means to transfer the contents of a bottle of wine into a new vessel.  For this process to be most beneficial the decanter will be larger and have more surface area than the original bottle.

Okay, but why do this? Fundamentally, decanting serves two purposes: to separate a wine from any sediment that may have formed and to aerate a wine enhancing its aromas and flavors creating more vibrancy before serving. Decanting is most associated with the service of older wines but, conversely, younger wines can also benefit from this step.  At the core of the matter decanting allows the wine to come in more contact with oxygen.  Oxygen, during its initial contact with a wine can be very helpful,  enhancing a wine’s flavors and softening it. Think about the wine being “caught” in the bottle, tightly stoppered under cork and capsule, a sleeping genie. Decanting wakes the wine up, helps it snap to attention and introduce itself with vigor.

Older red wines naturally produce sediment as they age (white wines rarely do). The color pigments and tannins bond together and fall out of solution. Stirring up the sediment when pouring will cloud a wine’s appearance and can impart bitter flavors and a gritty texture. The sediment is harmless but it’s not pleasant to get this material in your glass or worse in your mouth. It’s safe to assume that a red wine will have accumulated sediment after five to ten years in the bottle and should be decanted.

Here’s how to do it well:

  1. Set the bottle upright for 24 hours or more before drinking, so the sediment can slide to the bottom of the bottle, making it easier to separate. This advice assumes that the bottle was stored properly, cork down or on its side. 
  2. Locate a decanter or other clean, clear vessel from which the wine can easily be poured into glasses. Decanters can be extremely elaborate or quite simple. The best models are dishwasher safe, easy to handle and to store.  A simple glass pitcher will work just fine.  
  3. Remove the wine’s capsule and cork; wipe the bottle neck clean.
  4. Pour the wine into the decanter slowly and steadily, without stopping; when you get to the bottom half of the bottle, pour even more slowly.
  5. Stop as soon as you see the sediment reach the neck of the bottle. Sediment isn’t always chunky and obvious; stop if the wine’s color becomes cloudy or if you see what looks like specks of dust in the neck.
  6. The wine is now ready to serve from the decanter. Discard the remaining ounce or two of sediment-filled liquid in the bottle.
  7. Duckhorn Vineyards makes several age-worthy wines. Most famously, our Three Palms Vineyard Merlot and Howell Mountain Cabernet Sauvignon have the character and substance to gracefully age over a decade. The fortunate wine lover about to open and enjoy one of these wines with a significant bottle age should approach the task with a decanter in hand. Decanting will ensure elegant service as well as invigorate the wine’s flavors and aromas.

At the other end of the spectrum, new release wines can be “tightly wound” in their infancy. It is remarkable what happens to an introverted, shut down wine after as little as an hour spent out of the bottle and in a decanter. A wine that seemed somewhat dull and tight will suddenly awaken and have lots more to say!

Now you know much more about this useful component of my favorite participatory sport. Decanting isn’t fussy or mysterious, simply practical and beneficial.

The Magic of Bubbles!

Goldeneye Sparkling

While winemaking is a blend of art and science, it is the production of sparkling wine, or bubbles, that is perhaps most challenging to master. There are so many elements to sparkling wine that make it unique within the winemaking world it comes complete with its own vocabulary: dosage, tirage, remuage, disgorgement. In this post we'll explore many fun facts you never knew about sparkling wine.

It was the 17th century when Pierre Perignon first explored actively trapping the gas of fermentation in wine to create effervescence.

“Come quickly, I’m tasting the stars”, he cried. 


His dedication led to the development of both stronger glass to contain the pressure, and the use of tighter corks to keep the bubbles intact. Thanks, Dom!  Over 100 years later, in the 1800’s, Madame Clicquot (yes, the Widow, or Veuve) developed the practice of remuage (riddling) to remove the yeasty sediment left over from the second fermentation. By meticulously turning the bottles at an inverted angle, the yeasty sludge works its way into the slim neck of the bottle, for removal aka degorgemont (disgorgement).  Once you remove the cap and aforementioned sludge, the bottle is sealed with a tightly secured cork and muselet (muzzle, the charming wire cage) to keep the contents intact. It is after these innovations that sparkling wine took its place as the most elegant of beverages.

Perhaps one of the most fascinating elements of sparkling winemaking is the ability to anticipate what the future will bring. For assemblage (blending wines) of the base wines, the winemaker must predict what the wines will taste like with the addition of the dosage (the sugared liqueur addition that causes the 2nd fermentation in the bottle) and bottle aging before the wines are released. This decision happens typically 3-4 years before the wine is available for purchase, while the bottle is en tirage (state of aging).

Any grape can be used to make sparkling wine, but traditional grapes include Chardonnay, Pinot Noir, and the lesser known Pinot Meunier. The beautiful pink hue will come, as with still rose production, from limited skin contact with red grapes. The more complex, and daring, way to achieve the color of choice is by blending in a small portion of still red wine into a white wine base. Truly a task for a highly skilled winemaker.

Our own gorgeous and newly released 2015 Goldeneye Brut Rosé displays a pink hue and consists of 72% Pinot Noir and 28% Chardonnay, a modern classic indeed!

Lifecycle of a Grape Vine

Every bottle of wine has a story to tell, and that story begins in the vineyard. With each vintage, the unique interaction between terroir, climate, and weather dictate the narrative of each bottle. So, in this blog we will examine the lifecycle of the grape vine, the ultimate wine author.

Bud Break

budbreak

Come spring the vines reawaken from dormancy. From March to April the vines experience bud burst. From these buds, green leaves burst awake in preparation for photosynthesis with the warmer months. Bud break is a delicate time, as the new growth is in danger of spring frost and hail storms.

Flowering

Bloom

As bud break turns into vegetative growth, the next process of the grape vine begins from April to May. Flowering is when bunches of tiny flowers bloom from the new vine shoots. Grape vines are self-pollinating, so each of these flowers has the potential to turn into a single berry.

Fruit Set

Fruit Set

As the summer months set in, the pollinated flower drops its petals and tiny green grape berry clusters with seeds develop at the end of the stem. Although, not every flower is fertilized into a berry, so it simply falls off the vine. The fruit set stage of the grape vine is critical, as it becomes the initial indicator of the potential crop yield in harvest.

Veraison

Verasion

Come mid-summer, the green berry clusters begin to expose their color pigmentation. Verasion is the process in which the berry clusters begin ripening and turning purple or blueish in color. The heat of summer induces sugar development and ripening in each grape, while the cool evenings (depending on growing region) preserve natural acidity and freshness.

Harvest

Ridgeline

From September to November, for winemakers, viticulturists and wine country visitors, this is the most exciting time of the wine growing season! There is a palpable buzz and energy as winemakers’ taste, test, and measure brix, or sugar content, and determine when the grapes are ready to be picked. Harvest is when the grapes have reached optimal ripeness and are ready to tell the story of the vintage.

Dormancy

Pruning

After the seasons fruit has been collected during harvest, all fall leaf foliage falls to the soils and the vines go dormant. During this time, viticulturists are diligently pruning each vine in an effort to guide vine growth for next season. After four months of rest, the grape vine repeats this process effectively growing and telling the story of another season.

Harvest is the best season to visit wine country! The vines are lush with green foliage and plush purple grape clusters create the most picturesque visit. Our annual Paraduxx X2 Release Harvest Party took place on Saturday, September 29th! If you missed the festivities you can still book your fall reservation at ParaduxxDuckhorn VineyardsGoldeneye and Calera today!

How to Enjoy Large-Format Wine Bottles

Large Format Wine Bottles

Uncorking a large-format wine bottle is exciting and ceremonious! These bottles are rare in comparison to the standardized 750ml bottles, and they make for a practical investment. Large-format bottles are perfect for your cellar as they age more gracefully and make for impressive centerpieces during special gatherings. In this blog we are going to explore the evolution and benefits of large format wine bottles.

The Evolution of Wine bottles

It is believed that the ancient Romans, used glass blowing to create wine bottles. Yet, this glass was too delicate to store the wine, so they used amphoras, large clay pots, for wine transport and storage. The glass bottles they created were typically used as a decanter for dinners. In the 1700’s, coal-burning furnaces allowed for higher heat and allowed glass blowers to create thicker and darker glass. The production of the cork closure came shortly after and with that changes in wine bottle shape and size began to take form. It was discovered that the larger the bottle, the slower and more gracefully it ages. In, 1979, the United States deemed the 750ml the standardized wine bottle size, and the European Union followed suit, in order to ease trade.

Collecting Large-Formats for your Cellar

Large-format wine bottles make the perfect addition to your cellar due to their age-ability. The aging and oxidation process in a large-format bottle occurs more slowly, than the standardized 750ml, creating a wine with an enhanced flavor profile. With age the tannins soften, and the wine begins to express secondary and tertiary aromas creating a more complex wine.

So, the larger the bottle, the more age-ability. This is because the ullage, or oxygen sealed in each bottle of wine is the same despite differing bottle sizes. With larger formats, there is a larger volume of liquid interacting with that oxygen. In addition, large-formats are more resistant to drastic temperature variations and light damage due to the higher volume of liquid. For those interested in making practical wine investments, large-format bottles are your best option for cellaring and aging.

Celebrating with a Large-Format

Social gatherings are the perfect occasion for uncorking a large-format! Whether it’s for a holiday dinner, a family get-together, wedding or graduation, a large-format is sure to impress. Opening large-formats can take a little practice. So, we assembled a few suggestions:

  • Carefully, cut the wax off a large-format same as you would on a standard bottle with foil. Your cork screw knife should work great or even a serrated knife. Peel away the wax and be careful not to get any in the bottle.
  • If you are opening an older vintage wine, the ah-so wine opener is perfect solution. Vintage corks are delicate and the last thing you want is to destroy your large-formats cork. We suggest adding a neutral oil to the prongs to easily glide into the bottle neck and be cautious not to push the cork in. Simply twist and pull to cleanly extract the cork.
  • Once, you have uncorked your large-format, wipe away any sediment in the neck and decant your wine. Pouring from a large-format can be cumbersome, so the decanter is great way to ceremoniously present the wine while allowing the sediment to sit in the bottle and not your glass while at-the-same-time aerating the wine.

Within the Duckhorn Portfolio, we offer a selection of magnums and double-magnums for your next celebration or cellar. Shop online here and enjoy!

How To: Picnic Like a Pro

Picnic like a pro

It is officially summer and time to head outside for your dose of Vitamin D! When the Events Team is not busy dreaming up the next Duckhorn Wine Company event, we are crafting our own al fresco adventures. Follow these three easy steps below to picnic like a pro.

1. Prepare

With the busy work week weighing on many of us, it can seem daunting to put together a well-organized weekend picnic. Lessen your stress, and put together a picnic-edition “bug-out” bag before the summer season starts. Keep a check-list of items included in your basket, use and replenish when you’re ready to hit the road again.

Summer Picnic Bug-Out Bag Essentials:

  • For service: reusable dinnerware, including plates, utensils and stemless wine glasses; corkscrew, cheese board and an all-purpose knife
  • Protect against the elements: blankets, clothing to keep warm, sunscreen and bug spray
  • Clean-up duty: wine stain remover, trash bags, napkins and wet wipes

2. Pair

The time is now to enjoy your summer sippers! Pack the right wines and serve at the right temperatures to pair perfectly with your al fresco provisions. Our favorite picnic pairings include Duckhorn Vineyards Napa Valley Sauvignon Blanc, Paraduxx Napa Valley Rosé and Goldeneye Anderson Valley Pinot Noir.  

Traveling Beverage Hack:

  • Partially or completely freeze non-alcoholic beverages to use as ice-packs to keep wine and food at the perfect temperature during transit

3. Provisions

Avoid the charcoal smudges and sandy-sandwiches, prep all foods in advance to be enjoyed at ambient temperature. With less on-site prep work, hosts can make the most of their weekend adventures too.

Culinary Counsel:

  • Accommodate for all: Prepare for any pop-up dietary needs, packing at least one gluten free dish, one vegetarian dish and one non-dairy dish
  • Noshing: cheese wedges and crudité with dips keep a crowd coming back for more
  • Keep it light: opt for fresh, seasonal ingredients, keeping friends energetic for that summer frisbee match 
  • Dressing on the side: store dressing in a shakeable jar and toss just before service to keep green and pasta salads fresh
     

Ready to let someone else do the heavy lifting? The Duckhorn Events Team extraordinaire is ready to host your next wine country experience. Learn more about planning your next weekend adventure with our team.

The Story Behind Duckhorn Portfolio’s Pinnacle Wines

Forty years ago, Dan and Margaret Duckhorn along with their winemaker had a passionate discussion at the dinner table about making a cuvée, or the finest red blend. Instead, they chose to focus on varietal wines, yet Duckhorn Vineyards had remained intrigued by the artful blend of a cuvée. In 2006, that dinner discussion from 30 years ago came to fruition; Duckhorn Vineyards released their first cuvée or pinnacle wine aptly named, The Discussion.

Today, within the Duckhorn Portfolio, there are four Pinnacle wine offerings from four of our seven wineries, Duckhorn Vineyards, Paraduxx, Goldeneye and Canvasback. These wines are 100% estate grown and celebrate our best blocks from our top estate vineyards.

Our four pinnacle wines are distinctly different and capture the essence of each winery and region. The Discussion from Duckhorn Vineyards is classic and elegant embodying the best of Napa Valley Bordeaux varietals. Paraduxx X2 stylishly blends mountain fruit and valley floor fruit, beautifully demonstrating the subtle art of the blend. Our pinnacle Pinot Noir, Ten Degrees, from Goldeneye is complex, earthy and rustic, perfectly capturing the natural intensity of Anderson Valley. The Grand Passage is concentrated and complex, beautifully embodying the desert-like climate of Red Mountain in Washington State. All four of these wines are ready to drink now and ideal for aging in your cellar for 10 to 15 years.

Duckhorn Vineyards The Discussion

The Discussion commemorates a longstanding dream of Dan and Margaret Duckhorn’s. The primary blend is always Merlot and Cabernet Sauvignon, representing our belief in the timeless union of these two noble Bordeaux varietals. The Discussion embodies the depth and complexity of Duckhorn Vineyards renowned estate program, resulting in an elegant wine with pure fruit flavors combined with silky tannins and savory notes.

Chatting with Decoy Winemaker, Tyson Wolf

Each harvest season is a blank canvas and the winemaker is given the opportunity to paint the perfect vintage! As Decoy begins its twenty-second harvest, I sat down with Winemaker Tyson Wolf to discuss the 2017 vintage.

Ridgeline Vineyard in Alexander Valley

With the heavy rains this year, the question on everyone’s mind is how is the vintage looking? Our winemaker says the grapes are superb, with his first pick being of Sauvignon Blanc from the Alexander Valley. Fortunately, August has seen consistently warm weather which is balancing out the moisture brought on by California’s out-of-character rainy season. The excitement of Harvest is visible throughout Sonoma wine country!

Tyson in the Vineyards

Harvest is a culmination of the year’s climate and local geology, bearing fruit that is evocative of a place. According to Tyson, Harvest is the most important part of the winemaking process, setting a tone for the entire year of winemaking. It all starts with picking the grapes! Knowing when to pick each block of grapes is a skill. For Tyson, grape picking involves an analysis of not just the grapes chemistry but also of its flavor profile as well as an evaluation of how the flavor will continue to develop. It involves having the foresight to taste a single grape and understand how that grape will translate to the finished product, in the bottle!

Blend Tasting

Tyson's personal challenge every year is to make each vintage better. He and his team frequently taste the past two vintages and decide how to tweak the wines to achieve the ideal translation of the given varietal. For instance, Tyson is most excited to play with the second vintage of Decoy Rosé and add more Syrah to create a brighter, crisp Rosé with exotic fruit notes. From the picking of the grape, to the blend and barrel regime, winemaking most certainly is a labor of love.

Decoy wines aim to translate a sense of place, transporting the wine taster to Sonoma County and imparting a tasting experience that is much more than just the fruit, oak, and spice. Tyson says part of the fun of growing and making wines in Sonoma County is the diversity of climates. The Pacific Ocean offers a marine influence with cool coastal winds and morning fog while another microclimate exists that is warm, dry and mountainous. Sonoma County is unique in that it is able to communicate a variety of terroirs!

Cheers to the 2017 vintage and to a successful Harvest!

Harvest Celebrations Around the World

For as long as humans have depended on agriculture for survival we have organized our customs, mythologies, and calendars around the harvest cycle. The tales of Demeter and Persephone, Selu the Cherokee Corn Mother, the Roman Ceres, and the Norse Freyr speak to us of people whose very lives depended on the beneficence of mother nature and bountiful harvests. Every culture in every part of the world has some sort of harvest celebration thanking divine nature for the gifts of the earth. We at Duckhorn Vineyards christen each new harvest with an annual blessing of the grapes. On the first day of picking as many people as possible flock to the crush pad to taste the grapes, share Goldeneye sparkling wine, and eat donut holes. This simple toast marks the thankful end of another growing season and the beginning of a 3-month slog of long harvest days. Harvest culminates in a party where we celebrate the successful (hopefully) and bountiful crop of new wines by eating tacos, drinking ice cold Modelo, and maybe riding a mechanical bull. Check out some of the fascinating ways other cultures celebrate harvest, though sadly without donut holes or Modelo.

  • Rice Harvest, Bali Indonesia  Dewi Sri, the rice goddess, is venerated in Bali, where rice is the staple crop. During the harvest, villages are festooned with flags, and simple bamboo temples dedicated to the goddess are erected in the upstream, most sacred corners of the rice fields. Small dolls of rice stalks representing Dewi Sri are placed in granaries as offerings.
  • Chanthaburi Fruit Fair, Thailand  Chanthaburi is known for its profusion of beautiful native fruits. During the summer harvest, the annual Fruit Fair exhibits exotic durians, rambutans, longans, and mangosteens in vibrant arrangements. There are produce competitions and art displays, and the opening-day parade features floats made from thousands of tropical fruits and vegetables.
  • Madeira Flower Festival, Portugal  Funchal’s April flower festival marks the arrival of spring. Each of the island’s children brings a flower to create the colorful Muro da Esperança (Wall of Hope), and intricate flower carpets line the streets.
  • Incwala, Swaziland   In late December, branches from the sacred lusekwane tree are woven into a bower for the king, and only when he eats the first fruit can his people partake of the harvest.
  • Olivagando, Magione, Italy  Magione’s two-day festival in November celebrates both the feast day of St. Clement and the local olive harvest, bringing together everyone involved in the production of olive oil. A priest blesses the new oil at a special Mass, and the town hosts a lavish medieval dinner at its 12th-century castle.

Well, here we go…

It is hard to believe another year has passed and that we stand on the precipice of another harvest. I probably say this every year, but where has the time gone? It seems like only yesterday we were putting the finishing touches on the wonderful 2016 vintage, now soundly ensconced in bottles or barrels. The 2017 season started off much differently than the last 3 years, with a deluge of rain. Most areas received significant precipitation, filling up reservoirs, creeks, and the soil profiles of our beautiful estate vineyards. This boost of available water, while desperately needed, has changed the nature of our Estate Viticulture team’s challenge this growing season. Higher water availability allows the very fastidious and efficient grape vine to focus additional energy on vegetative growth. The added leaves, shoots, and laterals make extra vineyard passes a necessity to allow for appropriate shoot selection, leafing, and suckering to prevent shading and ensure the proper balance of fruit to canopy. The additional photosynthetic machinery can also be a problem later in the season, driving excessive transpiration and sugar production, along with the potential for higher methoxypyrazine production (the chemical responsible for bell pepper taste in Bordeaux varietals). Needless to say, our Estate Team has met the challenge head on and the Estate vineyards have never looked better. We have started our grape analysis, and all indications are that harvest will start in earnest sometime late next week, or early the week after with Sauvignon Blanc or Semillon for Duckhorn Vineyards. More to come in the days and weeks ahead!
