AGREED 100% This is a bad thing all around! They will eventually monopolize the market forcing us to purchase lower quality over refined products... I will no longer purchase from these two (once fine) establishments. Hopefully the remainder of our beloved small, home brew supplier 'DON'T SELL OUT!'
I use 2.5 gallons of tap water for the boil. When topping off, I use jugs of purchased purified or distilled water. Almost frozen.. This also helps cool the wort quickly. I never had an issue.
