👇🔥Well there it is. Thus far 2026 is already ranking #4 for number of hot days (defined as >34°C) as of only June 28th. Based on the current 10-day forcast this year is on track to absolutely smash all previous records. 😬😬 #wine #viticulture #climatechange

👇🔥Maybe to be expected, but through last Saturday 2026 (purple line) is tracking as the hottest year on record in Bordeaux. Look at it kick up in late May (around day 140ish) It will be going vertical during the next 10 days and the gap should become more obvious. 😬 #climatechange #wine #viticulture

In this grower participative study on Pinot Noir, the “high yield = low quality” paradigm proved grossly oversimplified: yield reductions didn’t consistently improve ripeness or quality.🍇🍇#viticulture #wine buff.ly/HzoTSs4

👇100% Agree. The AOC regulations are antiquated. Although established with good intent; the climate in Bordeaux is completely different today. Most producers lack the acclaim to leave the AOC making exits like this important in that they could influence positive change for the remaining producers.

👇Some severe water stress in our experimental vineyards @isvv-bordeaux.bsky.social Shedding leaves is adaptive, reducing leaf area and thus water loss. The negatives: yield decreases can be significant and leaf drop exposes fruit making it more susceptible to sunburn. #Drought #Vineyards
