To be considered a wheat beer, the mash should contain a large quantity of wheat in comparison to the barley. Wheat contains more protein than barley which contributes to a thick, long-lasting head. Whilst it contributes little to the flavour, it does add a silky mouthfeel and creates the haze seen in most wheat beers.
Wheat beers come in several styles with the most prominent being the German weissbier and the Belgian witbier. German weissbiers tend to be heavy on banana and clove flavours which are perfect when enjoyed on a hot summer's day. The witbier has lighter carbonation and is always spiced, often containing coriander and orange peel.
Wheat beers are highly effervescent and most are light in flavour, making them great summer beers.
