Wine A to Z

Ullage

The gap between the bottom of the cork and the top of the liquid in a bottle of wine. In a young wine, the ullage should be small – the level of the wine should be about the middle or upper neck of the bottle. The ullage usually increases as the wine ages.

Underbrush

Aromas or flavours that suggest dampness, wet leaves or slight decay.

Unripe, under-ripe

Grapes that do not reach optimum ripeness; green.
