1 ) Forget advice about not drinking homebrew whilst brewing. A brewer needs inspiration.
2 ) Eat a breakfast burrito prior to brewing. Sustenance is important for the brewer that excels.
3 ) Remember that the only style guideline that matters is... Crap, can't think of one that matters.
4 ) Avoid setting the dog on fire. Non-adherence to this can cause the spousal unit to curtail brewing activities and you'll end up rethinking point of advice #1.
5 ) Buy a headlamp. Brewing in the dark sucks.
6 ) Don't grab hot items of equipment with your bare hands.
7 ) Leave plenty of space between your nonheat tolerant equipment and your 640,000 BTU burner.
8 ) Be prepared. Have extra thermometers, hydrometers, pint glasses, cigars, and breakfast burritos on hand.
9 ) When brewing outdoors, brew in a covered space. Boiling wort attracts snow clouds. Even in July.
10 ) Send homebrew samples to me. That will allow me to give much more detailed and individualized advice. This is likely to be a very iterative process, so keep my address handy each time you package your beer.
