Well, based on this thread, my next project is a son of fermentation chiller, which I should have it complete by this weekend. I just find it interesting how some things about brewing you find out way too late in your brewing career, that could have changed the whole game. Like temperature control, yeah they say to keep it around 70F, but I didn't know how critical it would be. That and the fact that I've made about 15 batches (extact and all grain), and I've made a starter for most of them, and I even built a stir plate. But I didn't realize it till last week that I'd been following the wrong instructions on a yeast starter, I've only been making 500 ml starters! Whoops! I suppose it just depends on the brewer. Yeah it's fun to get people started in brewing beer, and yes, you do end up with beer as a result. But it is when you come to the point where you are not satisfied with mediocre tasting beer, and you are on a mission to make that great beer, and you won't be satisfied until that point. I am even a little nervous about giving away some beer to a coworker, because it has a little too much esters because of a high fermentation temperature, even though I don't think he would notice or care.
