since i am beyond bored and still waiting for supplies to come, i thought about doing a smaller batch (2.5 gallons or less) and use priming sugar for the carb. so i go to the calculator and its asking for co2 volume.. i have no clue. i threw in a couple different number just to see and i was getting 1.5oz to 2.1oz... not a big difference but,, since im here i thought id ask.. what is that? how do i calculate it? there are a few other things (that i cant think of right now) i was looking around at other calculators to get a better idea of what to do with this,,oh yeah! mash/water ratio stuff. i think im going to end up around 6.5lbs of grain, so 2 gallon of mash water. so i transfer to ferment vessel and sparge a half of a gallon? i remember going through some of them (calculators) and they want to know how much it will be. idk. im guessing 2.5 because thats all my ferment will hold. its not real important.. im making this with extra stuff from another "real" batch i will be doing in the future.. this one is going to be stuff i have around the house. 18.25oz of quaker oats.. 5.35oz of raisen bran!!!! vannila almond baby!!! .5oz of both vienna and munich malt 4lbs of 2 row. 4 different kinds of hops added at different times. i'll call it, GOAT SODA. from all the oats in it and i am a big fan of "the big lebowski". he orders a couple of "oat sodas" and im goatee so,,,,,,could end up being the greatest beer know to man!!!! or a bucket of shite.. probably the later of the two. its a quarantine beer. what do you want? but anyway,,, whats the co2 volume of what i expect to 2.5 gallons of shite?
