Why does Northern Rhône Syrah taste like that?

Characteristically medium-plus tannin and medium-full body. Commonly associated with blackberry, black pepper, olive, cured meat.

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, medium-minus acidity and full body. Commonly associated with apricot, peach, honeysuckle, orange blossom.

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.

A wide day–night temperature range is associated with better acid retention, because cool nights slow the respiration that consumes malic acid while warm days continue to ripen the fruit.

Not claiming: That altitude or continentality guarantees high acidity. Both widen diurnal range on average and neither determines the outcome.

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.

Vanillin and oak lactones are extracted from oak into the wine, in quantities that fall sharply with each use of a barrel.

Varies: Species, grain, seasoning, toast level, barrel size and the age of the barrel all change what is extracted and how much.

Not claiming: That oak produces buttery character. That comes from malolactic fermentation. Nor that a given oak origin yields a given flavour.

Fermenting two varieties together rather than blending them afterwards.

Not claiming: That every producer of this style uses this method, or that using it is required.

Slow oxygen ingress through the staves and bung promotes polymerisation of tannins and anthocyanins, which stabilises colour and is generally associated with a softer perception of tannin.

Not claiming: That an old barrel is equivalent to a steel tank. Aromatic extraction falls with use; oxygen permeability does not.

Including stems in the ferment, which adds structure, spice and aromatic lift.

Not claiming: That every producer of this style uses this method, or that using it is required.

Whole-bunch fermentation is commonly used for Syrah in the Northern Rhône and by producers elsewhere, contributing stem tannin and aromatic character alongside partial carbonic effects.

Varies: The proportion used varies from none to complete, and stem ripeness matters more than the proportion.

Not claiming: That whole-bunch inclusion produces freshness. That is a stylistic description rather than a demonstrated effect.

Hermitage and Côte-Rôtie routinely age twenty years or more; Crozes and Saint-Joseph five to ten.

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.
