材料：麦芽5kg、酵母适量、酒花（干花）适量。
1、准备材料。

2、将准备好的5kg麦芽磨碎，当达到既有磨碎的淀粉，且麦芽表皮保留较完整结构的状态时即可。

3、糖化：将磨碎的麦芽均匀倒入糖化罐，加入15L热水混合，使温度控制在66-68℃，同时调节PH值在5.2-5.4。糖化时间约1小时，使淀粉完全转化为麦芽糖。

4、收集麦汁：完全出糖后收集麦汁，这个过程需通过多次洗槽，将藏在麦芽里的麦芽糖洗出来。洗糟后测量糖度在14.5P左右，收集到的麦汁取适量用于酵母活化，其余送去煮沸。

5、 煮沸：将麦汁倒入煮沸罐煮沸，同时加入适量酒花，该过程持续约1个半小时，煮沸后糖度约为17-18P。

6、冷却：将煮沸的麦汁迅速冷却到适宜接种酵母的温度，约23℃。

7、发酵：将冷却后的麦汁转入发酵罐，充氧15-30mins，并加入适量酵母，温度控制在17-19℃，发酵约7-14天。

8、最后，只需要慢慢等待酵母工作完成后，便能享受那口味醇厚、唇齿留香的啤酒了。

啤酒的种类很多，其生产工艺也不尽相同。北京金汉森啤酒技术公司采用的是德式的酿酒法，自酿啤酒的方法如下：麦芽要粉碎之后，进入糖化锅相应比例的料水，在糖化锅里糖化做碘检，碘检合格之后送去过滤，之后要洗糟，再煮沸，再回旋沉淀，进入发酵罐之后，在加酵母，充氧。每天测糖度，当糖度降到2-3度时封罐。低温储酒1-2星期，送去啤酒过滤。出来的就是啤酒了
