The last few days have seen a moderate cool down in temperatures and moderate onshore flow. This has slowed sugar accumulation and respiration of acids in our ripening grapes. This weak trough looks to be nudged out by a moderate ridge towards the middle of the week, pushing temperatures upwards towards normal through the end of the week. Winemakers, grower relations folks, and vineyard managers keep a close eye on the weather as day to day variations in temperature, wind, fog cover, and precipitation can have significant impacts on picking decisions and ultimately wine quality.
