Furmint is one of the world’s greatest white grapes, although very few people are familiar with it. They might have heard of – or even tasted – a sweet Tokaji (the wine is spelled with an i, the region without) – but dry versions of the grape are harder to track down. So well done Sainsbury’s for listing this taut, racy, stony example with fine texture, citrus and white pepper flavours and a long, refreshing finish.
