BODY can be quite a confusing concept, but is so often spoken about when we refer to wines, reds in particular.  Essentially it is how the wine feels in the mouth, and the weight and texture to it. Alcohol adds weight, and combined with higher tannins and fruit components will all work to increase this perception of ‘body’.  A full-bodied wine has, therefore, higher alcohol, tannin and intense fruit flavours. Light bodied wine would have delicate flavours, lower alcohol but perhaps higher acidity.
