i've been brewing about a dozen times. but only from kits. doing everything from start to finish. but the yeast is provided. i just assumed it's basically an optimized baking yeast. also when talking to professional brewers they never really get into the yeast but talk about hop all day long. so i assumed that's where it's at.
You’ll get pepper flavors from the most boring grain bill and hop choices you’ve ever seen.
As you get further into brewing, and more expertise, you’ll end up caring more and more about yeast. If you’re chatting with pro brewers, usually if you’re there with a sanitized mason jar when they are harvesting yeast, they’ll give you some of their strain if it’s not something secret. Then end up with way more than they can use.
You can go down the rabbit hole trying to figure out what the best brewers use, like Trillium brewing. There are rumors but they sure won’t admit it, the yeast is the secret sauce, the hops are on the label.
