Perhaps I haven't yet drunk a decent prosecco but it seems pretty wishy washy to me..
Is Cava no longer a thing? Much crisper and fuller imo.
We have a new wine bar which sells prosecco by the bottle and glass but not champagne.
I'd pay a couple of quid more for a glass of champagne anyway. Alternatively a decent Cremant can be great ( but woefully hard to find in the UK)
