always have a game plan. My worst brew days were spur of the moment brews, with not really enough time to do everything. Get preped the day before. I like to get all my equipment pre washed and layed out, ready to go. Measure out hops, and put them in there marked bowls, ready to toss in. Have water ready and measured. Grind all grains. Etc......I like to be able to wake up, walk into my brew room, and just start going at it. The plan is in place, and everything is ready to throw in.
Another good tip is when you are done, CLEAN EVERYTHING. Dont put it off for a few hours, or whatever. When grain, hops, and wort dry, its like concrete. Especially the mash tun. Clean it out while its still hot, comes out crystal clear. Same with boil kettle. I wash it out as soon as i put the lid on my bucket. The dried hop residue around the top lip is a ***** to get off.
Sanitation is important, but people take it too far. There is no reason to make up 5 gallons of star san for brew day. I usually make up a half gallon in a small pail, and fill my star san squirt bottle. Brew day doesnt consist of much sanitizing. Fermenter, air lock, bung, and thats about it. I do like to dip my hands in the star san whenever im gonna touch anything that needs sanatizing. I love having a squirt bottle full, as well. You can squirt everything you want. Hit the rim of the bucket, and the lid before you close it up. And so fourth. You will use most of your star san at bottling.
Be patient. This one is almost impossible. But let your stuff be, and let the yeast do there work. I think a lot of people will disagree, but most beers can be bottled in about 10 days. I do a lot of ipa's. I will fe3ment for 7 days, dry hop for 3, then bottle. If i got time. They usually will be carbed in 3-5 days. Of course it will get better with time, but most session beers are fine and tasty in this time frame. Bigger beers, malt forward beers, and ciders i let go about twice as long.
I wish someone had told me all this stuff when i started. i had to learn from mistakes :/
