7 Reasons For Boiling [an all-grain] Wort
"To sterilize the wort: As homebrewers, we want as much control over our beer as possible. Beer yeast is (usually) the only thing we want growing in our beer. Boiling the wort kills off any microorganisms that may be in the wort or other ingredients. Sterilization requires a minimum of about 20 minutes of boiling."Back in 2015, here at HomebrewTalk, it was suggested that "If you don't boil, expect the beer to sour ..."
Agreed.
With a high DP base malt, the mash may be done in 20 minutes. A 20 min boil would cover sterilization.
Personally, with Maris Otter (IIRC, it's a lower DP malt) and a malt forward style (Irish Red), I get better results with longer mashes (45 min) and boils (45 or 60 min). |
