Decoding the wine label: Alto

Wines from grapes grown in higher altitude areas with cooler climate has become quite the trend recently. This specific growing environment gives intense flavor but elegance and freshness to the final wines. To highlight and champion these conditions more and more winemakers are starting to use alto as a marketing and labelling term to show their grapes were grown in high altitude vineyards.

Alto means high, referring to altitude when talking about wine, in both Spanish and Italian. Recently higher altitude locations have been planted more and more. A few decades ago, these areas were not seen as suitable for growing quality grapes as the climate back then was too cool. Today, with many producers witnessing a rising temperature, and a lot of new techniques in the vineyard, these areas are finally becoming viable. The higher you plant the cooler the temperature will be, but you will also receive more sun which in turn helps ripen the grapes. The temperature will be quite warm during the day, but very cool at night. This leads to ripe fruit aromas developing during the day, followed by a cool nighttime keeping the fresh acidity in the grapes, the best of both worlds for the grapes.

In Italy this development has been very prominent in northern Piemonte in the last decade. There is now talk about an area called Alto Piemonte, comprised of a few different wine regions. They are all located higher up in the mountains, and like the most famous wines from Piemonte many are based on the Nebbiolo grape. The most well-known wine regions would be Ghemme, Gattinara, and Boca.

But Alto Piemonte is not the only area where the term is used. In quite a few cases, in both Italy, Spain, Argentina and Chile the term can be seen used as part of a producer name or even as the name of a specific wine, sometimes to convey the wine is from a high planted vineyard. It is not uncommon however for winemakers to use the term to show it’s their highest quality wine, not a wine from high altitude.

More wine growers have shown interest in high altitude vineyards lately, and the record of the highest planted one is something a few are trying to beat. It’s safe to say the positive effects the altitude has on the growing grapes mean these vineyards are here to stay, and terms as alto may be used in more languages soon.
