Though it is fairly easy to brew beer, there is still the possibility that you might make some simple mistakes that will destroy your batch of beer. Let this post be a warning to you before you get started on the brewing process.
Always thoroughly clean your brewing kit and other brewing supplies before you get started. Bacteria in your wort can wreak havoc on the fermentation process and ruin the flavor of your beer. Cleaning your supplies will also ensure that there isn’t any unwanted substances or objects in your beer. I love my cats very much, but not enough to drink cat hair beer (I wouldn’t be surprised if someone has tried this).
Don’t forget to add the yeast to the wort. Yeah, you laugh about it now, but I have heard from many sources that forgetting to add the yeast before sealing the fermentation bucket/tank is a fairly common mistake made by home brewers. Without yeast, you will end up with a batch of flat non-alcoholic beer. Yummy.
Don’t syphon directly from the bottom of the fermentation bucket. During fermentation, a lot of sediment settles along the bottom of the bucket and if you hold the syphoning tube too close to the bottom, it will suck it up and move it into the bottling bucket. In many wheat beers, moderate amounts of sediment may be desirable but many people freak out when they see floaties in their beer. The sediment in beer will not harm you, but it might taste a little chunky going down.
Lastly, avoid the temptation of prying open the fermentation bucket before it is time to bottle/keg the beer. This also helps prevent bacteria and other flavor destroyers from entering the beer. Just trust that you took all the right steps leading up to the point where you sealed the bucket and let the yeast do what it does best.
