Blanc de Blancs

Of all the sparkling wine on our shelves, this is the style with nowhere to hide. Blanc de blancs — literally "white from whites" — leaves the black grapes out entirely, and in Champagne that almost always means Chardonnay on its own. There is no Pinot Noir to add flesh and no blending to cover a thin base wine: the fruit must be good and the winemaking exact. That is why we give it its own shelf rather than folding it into the wider sparkling white wine range — done well, it is the purest expression of place that fizz can offer.

What the style actually is

The heartland is the Côte des Blancs, a chalk slope south of Épernay where villages such as Avize and Le Mesnil-sur-Oger grow Chardonnay of famous precision. Beyond Champagne the term simply means "white grapes only", which is why Raventós i Blanc's 2024, from a biodynamic family estate in Penedès, builds its version on local varieties such as Xarel·lo instead. For you, the practical takeaway is this: expect a paler, more linear wine than a standard blend — lemon, green apple and a saline, chalky finish in youth, moving towards brioche, hazelnut and cream with time on the lees.

Champagne, and the chalk across the Channel

Start in Champagne if you want the benchmark. Charles Heidsieck's NV Blanc de Blancs carries the house signature: generous reserve wines that lend a toasted, patisserie depth, making it as much a dinner wine as an aperitif. Piper-Heidsieck's Essentiel Extra Brut takes the opposite road — very little sugar at disgorgement, so the Chardonnay shows bone-dry and razor-edged. Hand it to the guest who claims Champagne is too sweet. Then cross the water: the South Downs sit on the same seam of chalk, and English Chardonnay has learned to use it. Nyetimber's 2017 is polished and creamy after long lees ageing; Rathfinny's 2019, grown in Sussex's Cradle Valley, runs tauter and more saline; Langham's NV from Dorset chalk is the friendly place to start.

Beyond the classics

Italy gives two different answers. Ferrari's Maximum comes from Trentodoc in the Alps, where mountain-grown Chardonnay keeps its nerve while gaining real depth — a reliable choice when the table is mixed and the occasion matters. Tenuta Mazzolino's 2021 speaks for Lombardy's quieter Oltrepò Pavese, one for the curious. From Burgundy, the JCB Caviar Crémant de Bourgogne applies the same white-from-whites thinking outside Champagne's borders, while House of Arras's Tasmania bottling shows what slow, cool-climate ripening achieves at the far end of the earth — it is consistently among Australia's most awarded sparkling wines.

Choosing is simpler than it looks. Oysters and aperitifs call for the young, dry end — the Piper-Heidsieck or the Rathfinny. A dinner of fish, roast chicken or anything in a cream sauce deserves the depth of Charles Heidsieck or Nyetimber. And if you are simply curious what all-Chardonnay fizz tastes like when it is done properly, open the Langham or the Ferrari first: ten bottles on this shelf, one idea — white grapes, chalk and patience.
