About Cabernet Sauvignon
Cabernet Sauvignon is the king of red wine grapes — producing the world's most celebrated wines with deep color, firm tannins, and complex flavors of blackcurrant and cedar. It's adaptable but demands a long, warm growing season.
Cabernet Sauvignon requires 100 chill hours — the number of hours between 32°F and 45°F during winter dormancy. Without enough chill, the tree may fail to flower properly or produce poor fruit.
⚠️ Common Challenges
Requires 170+ frost-free days to ripen; late budbreak but very late harvest means frost risk in cool climates; needs expert pruning and canopy management.
❌ Common Misconception
Will Cabernet Sauvignon produce more fruit in colder climates?
Not necessarily. Cabernet Sauvignon only needs 100 chill hours. Planting in very cold zones (5 or colder) risks winter damage without improving fruit production. The ideal zones are 6-10 where the tree gets enough chill without excessive cold stress.
If you plant it, write it down.
