Personally, I do not drink much, but there are some obligatory choices that always keep in the pantry:
for roasts and cheeses, usually buy Chianti Classico, Monte Maione from Watrose is one I like
for aperitifs and cocktails prosecco Gera Valdo, from Waitrose
for cooking and cool with fish, Laurence de Veyrac Picpoul de Pinet found a bit everywhere. You can search here https://haywines.co.uk/
