Flammkuchen

Alsatian thin-crust tart — a cracker-thin dough topped with crème fraîche, lardons, and thinly sliced onion, blistered in a wood-fired oven. The wine has to handle the cream's richness, the smoky bacon fat, the sweet-sharp onion, and the slight char from the oven. Bubbles or cutting acid are the structural requirement; tannic reds will fight the cream; oaked whites will smother the delicacy.

Pairs Perfectly

Riesling, dry, Alsace, France. The wine grew up beside this dish — sec Alsace Riesling has the cutting acid for cream and bacon fat, the mineral lift for the onion's sweetness, and the texture to sit alongside the crisp dough. Regional fidelity at its most precise.

Pairs Well

Crémant d'Alsace, France. Pinot Blanc-led traditional method, rounder than Crémant de Bourgogne, with bubbles that physically cut the cream and bacon fat where a still wine works harder. The same Alsatian aromatic register as the Riesling, in sparkling form — particularly good when the lardons run heavy.

Old-vine Chenin Blanc from Stellenbosch, South Africa. Bush-vine Stellenbosch Chenin brings the body and gentle texture that engages the crème fraîche, the cutting acid that handles bacon fat, and a subtle quince-honey character that picks up the caramelised onion. The Cape's most underrated white for cream-and-fat contexts and a quietly precise alternative to Alsace Pinot Gris.

Avoid

Tannic reds (the cream and bacon fat make them taste harsh); heavily oaked Chardonnay (oak vanilla muddies the dish's clean smoky-sweet register); high-alcohol whites (overwhelm the delicate dough and cream).

Failing That

A Pinot Blanc from Alsace.

If All Else Fails

Dry sparkling wine, house Champagne.
