Gose

Gose is a warm fermented beer that is usually brewed with at least 50% of the grain bill being malted wheat (with the rest being malted barley such as Pilsner malt), fruit syrups- such as lemon, coriander- and salt - either added or a component of the water used. It acquires its characteristic sourness through inoculation with Lactobacillus bacteria, which is not a hop-tolerant bacteria and which provides only a light acidity. Unlike some beers, such as India pale ales, gose beers typically do not have prominent hop bitterness, flavours, or aroma and have a relatively low alcohol content of 4 to 5% alcohol by volume. Gose was first brewed in Germany. It does not comply with the Reinheitsgebot (German purity laws) because of the use of coriander and salt, but it is allowed an exemption on the grounds of being a regional specialty.
