Brewing a 1 gallon (All Grain) batch

Thanks, I just did a batch today and got lucky. I used 2 gallons and it worked out alright but I like your formula and I will save it. Thanks again.

 

0.15 Gallons per ounce of hops is really a lot, even for leaf hops. I suspect your Trub loss parameter is compensating for some missing parameter and/or perhaps for understatement of another parameter. But if it's dialed and works out for the types of batches you typically brew, that's the important thing.

 

Yeah you're probably right. It's kind've been my average over 50+ batches. Not sure how it came about really but it's developed in a spreadsheet formula and become more consistent over time. For the record, in the example given I start the boil with 1.65 gallons, end with 1.15 and roughly 1 gallon of that sans trub goes into the fermentor.

 

Not to derail the thread, but the basic question seems to be adequately answered, so a follow-up question...

Fermenters for 1 gallon batches - a one gallon glass jug seems to be cutting it way too close, so what do people use? I'm interested in the small batch approach as a means to experiment and work on technique.

 

The glass jugs I use for my one gallon brewing have a line on them which states one gallon and if you fill to that line there is plenty of room left in the jug. I do use a blow off tube until the bubbling stops, then switch to the three part bubbler.

 

Yep, they hold proly 1.25 gallons. Blowoff tube and fermcap will be your friends.

 

Five liter wine jugs work fine if you don't have too crazy of a krausen and you only fill up to a gallon.

 

I use the Mr Beer fermenters and they work great for 1 - 2.5 gal batches. They are inexpensive and easy to work with.

 

I do one gallon and ya I have to make sure not to fill the jug up to high. I did an FBS clone recently and filled it a tad too high and the airlock blew off twice. Hardest mess ever to clean up, I had to use a utility knife to scrap chocolate wort off the white walls.
