My biggest expense so far was buying the 20 quart pot. I already wish I'd purchased a larger one that could hold the whole five gallons. It essentially seems like I'm making tea with yeast added after it cools down. I think I took too long to chill the wort down and I'm worried because the airlock on my tank isn't seeing any action yet. Me and yeast have a tentative relationship. Every time I bake bread I have trouble getting it to rise properly. So we'll see. Also, I forgot to take a before reading with my hygrometer so I won't know the alcohol content of this batch.
I'd recommend Papazian's Joy of Home Brewing.
