Which series suits which occasion
Start with the wine you drink most often. For burgundy and pinot noir you want a wide, rounded bowl where the aroma can gather; Vervino goes up to 95.5 cl and Vuelo up to 84.8 cl, which sounds excessive until you realise you only fill a glass like that to a third. For bordeaux and full-bodied reds, the rounder bowl of Kolibri at 55.9 cl is plenty. White wine sits well between 31.9 cl for riesling and 51.7 cl for chardonnay, where the narrower bowl keeps the wine cool for longer.
If you would rather not choose by grape, look at Simplify. That series is organised by flavour profile instead of wine region, with a glass for light, fresh wines at 38.2 cl and a roomier one for fruity, delicate wines at 55.5 cl. For the rest of the table there are water glasses from 36.7 to 39.8 cl, an all-round glass of 64 cl with a fill line, and carafes from 50 to 100 cl. Behind the bar you reach for Destille No. 1 or the Bar Premium line.
