I've been brewing a long time, and I learned most things the hard way. What would be the one tip that you would give to a newer brewer to save them from having to learn things the hard way? For me, it would be that you can mix up a gallon of star-san sanitizer and store it. Put some in a spray bottle, and instead of dunking/soaking, just spritz items to wet them thoroughly. Plus, you can and use and reuse. What is it that you know now that you wished you had known back then?
