Production process of cyperus esculentus craft beer

The invention provides a production process of cyperus esculentus craft beer, belonging to the technical field of beer fermentation. The production process of the craft beer comprises the following steps: raw material treatment, saccharifying, filtering, boiling, whirling, cooling, canning, fermenting, supplementation of materials for fermention, and carbonizing. The sugar-liquid separation of cyperus esculentus is realized by utilizing a physical oil squeezing technology and a chemical liquid separation technology; the product characteristic that a beer body has high aroma is realized through a fed-batch fermentation technology in the later period of fermentation, and a wider application scope of cyperus esculentus in beer brewing is provided. 本发明提供了一种油莎豆精酿啤酒的生产工艺，涉及啤酒发酵技术领域。本发明的精酿啤酒生产工艺包括：原料的处理、糖化、过滤、煮沸、回旋、冷却与入罐、发酵、补料发酵和碳化。本发明利用物理压榨出油和化学分液技术，实现了油莎豆的糖液分离；通过发酵后期补料发酵技术实现了酒体持有高香气的产品特征，为油莎豆在啤酒酿造中提供更广泛的应用。
