材料：麥芽5kg、酵母適量、酒花（干花）適量。

1、準(zhǔn)備材料。

2、將準(zhǔn)備好的5kg麥芽磨碎，當(dāng)達(dá)到既有磨碎的淀粉，且麥芽表皮保留較完整結(jié)構(gòu)的狀態(tài)時(shí)即可。

3、糖化：將磨碎的麥芽均勻倒入糖化罐，加入15L熱水混合，使溫度控制在66-68℃，同時(shí)調(diào)節(jié)PH值在5.2-5.4。糖化時(shí)間約1小時(shí)，使淀粉完全轉(zhuǎn)化為麥芽糖。

4、收集麥汁：完全出糖后收集麥汁，這個(gè)過(guò)程需通過(guò)多次洗槽，將藏在麥芽里的麥芽糖洗出來(lái)。洗糟后測(cè)量糖度在14.5P左右，收集到的麥汁取適量用于酵母活化，其余送去煮沸。

5、 煮沸：將麥汁倒入煮沸罐煮沸，同時(shí)加入適量酒花，該過(guò)程持續(xù)約1個(gè)半小時(shí)，煮沸后糖度約為17-18P。

6、冷卻：將煮沸的麥汁迅速冷卻到適宜接種酵母的溫度，約23℃。

7、發(fā)酵：將冷卻后的麥汁轉(zhuǎn)入發(fā)酵罐，充氧15-30mins，并加入適量酵母，溫度控制在17-19℃，發(fā)酵約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、唇齒留香的啤酒了。

啤酒的種類很多，其生產(chǎn)工藝也不盡相同。北京金漢森啤酒技術(shù)公司采用的是德式的釀酒法，自釀啤酒的方法如下：麥芽要粉碎之后，進(jìn)入糖化鍋相應(yīng)比例的料水，在糖化鍋里糖化做碘檢，碘檢合格之后送去過(guò)濾，之后要洗糟，再煮沸，再回旋沉淀，進(jìn)入發(fā)酵罐之后，在加酵母，充氧。每天測(cè)糖度，當(dāng)糖度降到2-3度時(shí)封罐。低溫儲(chǔ)酒1-2星期，送去啤酒過(guò)濾。出來(lái)的就是啤酒了
