Why does Vinsanto (Santorini) taste like that?

Characteristically very low tannin, high acidity and medium-full body. Commonly associated with lemon, grapefruit, sea salt, wet stone.

Not claiming: That every wine from this variety shows these characteristics. This is the range across the category, and site and winemaking move wines within and beyond it.

Characteristically very low tannin and light-medium body. Commonly associated with orange blossom, apricot, citrus.

Warmer growing seasons are associated with faster sugar accumulation and lower retained acidity, so fruit reaches a given potential alcohol earlier in the season.

Varies: Above the vine’s photosynthetic optimum the relationship reverses: extreme heat stalls ripening, inhibits anthocyanin synthesis and can raise sugar only through berry dehydration.

Not claiming: That warm regions necessarily make high-alcohol wine. Potential alcohol at any moment is a choice point; the producer decides when to pick.

Proximity to a large body of water moderates temperature extremes, which is associated with a longer, more even ripening period and a lower risk of both spring frost and extreme summer heat.

Varies: Maritime influence also raises humidity, which raises fungal disease pressure. It is not uniformly an advantage.

Not claiming: That a maritime climate is cool. Maritime describes variability, not temperature.

A Mediterranean pattern of wet winters and dry summers is associated with reliable ripening and with mild late-season water stress, which restricts berry size and raises the ratio of skin to juice.

Varies: Where the dry season is severe or lengthening, the same pattern produces damaging rather than beneficial stress, and irrigation becomes necessary rather than optional.

Not claiming: That water stress is beneficial as such. Mild stress helps; severe stress halts ripening.

Drying harvested grapes removes water, concentrating sugar, acid and phenolics. Higher starting sugar yields higher alcohol, and fermentation may stop before the sugar is used up.

Not claiming: That all appassimento wines are sweet. Amarone is fermented dry or nearly so; Recioto is not.

Prolonged contact with air produces acetaldehyde and, over longer periods, sotolon, associated with walnut, curry leaf and dried-fruit characters.

Not claiming: That these characters indicate a fault. In oxidatively aged styles they are the intended result.

Decades. Santorini’s sun-dried Assyrtiko gives extraordinary acidity alongside the sugar, and the mandatory cask ageing before release means the wine is already mature when sold.

Not claiming: That a wine of this style will develop these characters. Ageing potential varies by producer, vintage and storage, and most wine is better young.
