Beer lovers can now enjoy their wildest drink yet thanks to a yeast carried by wasps. AB Biotek from Peterborough in the UK has launched Pinnacle Crisp Sour — a brewer’s ingredient made from Lachancea thermotolerans, a yeast found in the bellies of wasps.

Traditional beer uses just four ingredients: grain, hops, yeast and water. Hops add the distinctive bitter flavor, and yeast converts sugar from the grain into alcohol and carbon dioxide. But yeast also adds aroma and flavor. The brewer must control its metabolism to minimize bad flavors and intensify good ones; some also choose to add ingredients such as sweet potato to increase aromas.

啤酒爱好者现在可以享受他们迄今为止最狂野的饮料，这要归功于黄蜂携带的酵母。来自英国彼得伯勒的 AB Biotek 推出了 Pinnacle Crisp Sour，这是一种由黄蜂腹部发现的酵母 Lachancea thermotolerans 制成的啤酒原料。

传统啤酒只使用四种成分：谷物、啤酒花、酵母和水。啤酒花增加了独特的苦味，酵母将谷物中的糖转化为酒精和二氧化碳。但酵母也会增加香气和风味。酿酒师必须控制其新陈代谢，以尽量减少坏味道并强化好味道;有些人还选择添加红薯等成分来增加香气。
