To be delivered tomorrow. I have been reading the instructions, and I know I will need several gallons of water, but I have no idea how much I will need. The instructions say to add 4 liters of water to the primary fermenter, add bentonite, add the juice, then fill the fermenter to the 6 gallon mark with more water. So, here are my initial questions: 1. How many gallons of concentrate are included in the kit? So I will know how much water I will need. 2. Should I use bottled drinking water? Tap water? Our water here is pretty hard. I want to make sure I have enough water on hand before starting. Thanks. I am very new to this. Just finished my first kit, bottled a week ago, so trying to get this one going while the garage is still warm enough.
