I generally do BIAB 6 gallon batches and mash/boil the entire volume, however I have an old 15 gallon conical that I plan on using for hard seltzers. Turns out my wife and daughter (and their friends) really like them as a boat drink.
My plan is to add @9 gallons of tap water treated with campden tablets to the fermenter and add the boiled 6 gallons of sugar/yeast nutrients to that.
My question is....are there any significant contamination risks with this approach? I have topped off smaller amounts with this tap water in the past with no real issues.
