COOL CLIMATE WINES IN GENERAL

Cool climate wines possess a distinct set of characteristics that set them apart from wines produced in warmer climates. The uniqueness of cool climate wines is largely influenced by the temperature and growing conditions of the region. Here are some key aspects that contribute to the distinctiveness of cool climate wines:

Acidity: The slower ripening process allows grapes to retain higher levels of natural acidity. Wines with elevated acidity are often crisper, fresher, and more vibrant, providing a refreshing and zesty taste.

Flavour Profile: The longer ripening period allows grapes to develop more complex flavours. Cool climate wines often exhibit notes of green apple, citrus, and stone fruits, along with herbal and floral aromas. The slow ripening process contributes to a greater depth of flavour and aromatic complexity.

Lower Alcohol Content: Cooler temperatures can result in grapes with lower sugar levels at harvest. As a result, cool climate wines tend to have lower alcohol content compared to wines from warmer regions. This characteristic makes them more food-friendly and versatile, as they pair well with a variety of dishes.

Elegance and Balance: Cool climate wines are known for their elegance and balance. The slower ripening process allows for the gradual development of tannins and other components, leading to well-integrated and harmonious wines. This balance contributes to the overall finesse and age-worthiness of the wines.

Aging Potential: Wines from cool climates often have excellent aging potential. The higher acidity and balanced structure can contribute to the longevity of the wine, allowing it to evolve and develop more complex characteristics over time.

Expressiveness of Terroir: Cool climates often highlight the influence of terroir on wine. The slower ripening allows the grapevines to express the unique characteristics of the soil, climate, and local geography, resulting in wines that reflect the specific nuances of the vineyard.

All of the above influences & characteristics seem similar, and we have 40o days like everywhere else. So what creates the difference in cool climate wines?

The answer is,

Diurnal temperature difference. This is the average difference between the highest daytime temperature and the lowest night time temperature during the growing season.

In our vineyard, the average daytime temperature is 23.38 o and our average lowest night time temperature is 11.83 o So our official diurnal difference is 11.55 o (23.38-11.83)

It means our grapes cool down easier & close to a level where grapes stop producing sugar. That is 10 o however at night there is no sugar production anyway.

Cabernet Sauvignon loves the hot days & cool nights

The vines are in fact snoozing which allows acid levels and phenols to balance up with the sugar levels before they have to go to work again the next day.
