Cabernet Franc

Meet the parent. Cabernet Franc is the grape everyone tastes second and should learn first — the older, more aromatic vine that, crossed with Sauvignon Blanc, produced Cabernet Sauvignon, and that DNA also names as a parent of Merlot. Where Cabernet Sauvignon is broad-shouldered and built to age, Cabernet Franc is its lighter, quicker, more perfumed relation: pale in the glass, softer in tannin, and unmistakable on the nose — leaf and graphite and crushed raspberry, with a violet lift.

The trick to learning Cabernet Franc is to stop treating it as "Cabernet Sauvignon lite" and hear its own voice. It ripens earlier and thrives where Cabernet Sauvignon sulks, so it has become the red of the cool Loire and a prized aromatic seasoning on Bordeaux's Right Bank. Fix the leafy-pyrazine core and the earlier ripening, and you can taste why the same grape can be a crisp Chinon one minute and a component of Château Cheval Blanc the next.

The one thing to fix first: what Cabernet Franc is

Cabernet Franc is the elder statesman of the Cabernet family. DNA analysis confirmed in 1997 that it is one of two parents of Cabernet Sauvignon (with Sauvignon Blanc), as well as a parent of Merlot and Carménère. It is believed to have come from the Libournais in south-west France, and its lineage in these regions is documented earlier than Cabernet Sauvignon's — planted in the Loire before Bordeaux records of it even begin, and known on the Right Bank as Bouchet by the 18th century.

The grape itself explains the wine:

• Thin-skinned, small blue-black berries. Less skin means lower tannin, paler colour, and a smoother mouthfeel than Cabernet Sauvignon.
• Buds and ripens early — at least a week earlier than Cabernet Sauvignon — so it thrives in cooler climates and, in Bordeaux, acts as an "insurance policy" against bad harvest weather.
• Aromatic and perfumed. Its calling card is a pronounced nose — violets, raspberry, graphite — that it lends to blends even in small amounts.
• Yield-sensitive. Over-crop it and the wine turns green and vegetal; keep yields low and the fruit and perfume come through.

The core profile — the same in every glass

Whatever the region, look for:

• Raspberry and red-berry fruit — brighter and redder than Cabernet Sauvignon
• Violet and floral perfume — the aromatic signature
• Graphite / pencil shavings and cassis on the darker end
• A green, vegetal strike — from leaf to green bell pepper (pyrazines)
• Light-to-medium body, medium-plus acidity, and softer, finer tannins

The green streak is the tell-tale marker: it's pyrazine-driven, more insistent when the fruit is underripe or over-cropped, and it's what separates a Cabernet Franc from its plusher offspring. New World examples often push it toward ground coffee and olive instead.

Where it grows

Cabernet Franc has two spiritual homes. The Loire Valley — Chinon, Bourgueil, and Saumur-Champigny — is where it stars as a varietal red, under the local name Breton. On Bordeaux's Right Bank (Saint-Émilion, Pomerol, Fronsac) it is a major blending grape and the soul of Château Cheval Blanc. Beyond France it appears across northern Italy (Friuli and the Veneto, where it's called Bordo, and increasingly in Tuscan Bolgheri), in cooler New World pockets from California to Argentina, and — ripening two weeks ahead of Cabernet Sauvignon — as a cold-hardy source of Canadian icewine in Ontario's Niagara Peninsula.
