So...we do a 60 or 90-min boil. Several things happen there......DMS precursors evaporate, color changes, hops get isomerized and the water get sanitized.
Now....how come many brewers use simple tap water as top-off water? Isnt there a chance to introduce bacteria into the wort?
Some people even say: "if you can drink it, you can brew with it". Might be true....but worth the risk?
Any thoughts on this?
Shall I always boil top-off water to be on the safe side?
Or shall I just buy bottled water? That is surely filter and clean enough to go straight into the fermentor without boiling, right?
