[quote=“inhousebrew”]I’d pitch half of a pack for simplicity but just know that one gallons are tough because just a small error can lead to a big difference. Too much boil off and you’ve got a 1.075 wort while too little and you got 1.040. A bit too many hops and you got too many IBUs and you didn’t boil off enough and now your balance is off. You think you hit your one gallon volume but you got a quarter gallon of trub. Stuff like that you don’t really think about.
Not to say you shouldn’t do it because you might as well with the gallon jug. Just have fun with it, don’t be to anal about hitting your numbers up front and attach a blowoff tube every time while fermenting really cool. Also, you might as well mess around with the recipes, do something huge and stupid you wouldn’t commit five gallons too. Use a crap ton of smoked malt for fun, or maybe a new type of hop. That’s what I do with small batches.[/quote]
Good points man. and 100% my reason for wanting to do it. I’m also in the process or learning to use beer smith. So i figure one gallon batchs will be a great way to do both. Guess ill get some water boiling and figure out my boil off rate.
Im not sure how to account for trub. Is a quarter gallon realistic for a one gallon batch? As far as hops will scaling a hop combination from a similar 5 gallon recipe work. I would assume utilization wouldnt be much different?
