Fermentation Process for Home Brewed Beer

Video Transcript

Hi! I’m Eddie Leal, and we’re going to continue on with the fermentation process. Once we add the yeast to the wort in the fermentation tank, the yeast begins feeding off the sugars creating the alcohol and CO2 content. Basically, what this is is the primary fermentation. This basically take between 4-7 days, depending on the beer style that you’re brewing. What we did here is we pumped the water into our fermentation tank. Basically, we’re pumping the wort from our brew kettle into our fermenter, and while we do that we cool the wort down. Now, the wort is approximately about 200 degrees when we’re bringing it from our brew kettle. What we do is we bring it down; we cool it down to our fermentation temperature. We mainly make ales here so, so I ferment at 68 degrees. So, basically when we cool that wort down, we cool it down to 68 degrees and we fill our fermentation tank at 68 degrees. During that time period, we keep it at 68 degrees here. This is the temperature control, and this will keep it at that fermentation temperature. After those 4-7 days, after the primary fermentation, the beer will sit in this tank from 1-2 weeks, depending on the beer; even longer if it’s a lager. The stronger it is the more alcohol is present, so it’ll take longer for it sit in the tank. That time period, what’s happening is the beer is aging inside the tank, where all the flavors are starting to balance out, so it takes about anther 1-2 weeks after the primary fermentation for the beer to balance out and age. If it was a lager, it even be longer.
