Welcome to Caane"s beer tips site
Dont brew to hot, anything over 26 sucks, and will slightly change the taste of beer.
Use ice to start a brew in summer, low yeast pitching temps keep the temp down a little
Brew in a larger bucket than you fementer filled with water im warmer months to keep the temp down, and if still to hot add a frozen 2-3ltr coke bottle every few hrs.
