Quick question, what's the least amount of beer I can make in one batch? I want to experiment with different recipes with the last amount of product possible. Two reasons, I can make a lot of recipes without wasting too much product and I can use trial and error to my full advantage. Will be making only IPA's if that's important. Best, Jim
A lot of homebrewers brew 1-gallon batches for the same reason that you state, to experiment. One problem with brewing a small batch is that when you draw a sample for your hydrometer reading (if you will be using a hydrometer, which by the way is an important tool) you begin to lose some of your beer before it is ready (although you can drink the sample for science ). You can purchase a refractometer which uses only a few drops instead of using a hydrometer. Another issue with making a small batch that I've read about is that according to some brewers you won't get full flavor from your hops by boiling them in such a small amount of liquid, although I don't have any personal experience to confirm that. That may be pretty important to you if you are brewing only IPAs. EDIT: here's a link to a search that I did of this forum asking for 'small batch' in the thread title. Maybe there is additional helpful info in there. https://www.beeradvocate.com/commun...=small+batch&o=date&c[title_only]=1&c[node]=8
Answer to your question is about 8 ounces. You could brew 8 ounces of beer I figure and after all is said and done, after racking, after fermenting, after losing trub, after spilling, you'll have about 3 ounces of beer to drink. But that is stupid. Don't do that. Instead consider making 2, 4 or 5 standard gallon brews. I'll tell you why. The ingredient cost of making 1 gallon vs 5 gallons is so little as to be non existent. If $10 is too much money find another hobby. Your QC program is not robust enough to scale up 8 ounces to a whopping 5 gallons, much less 2 gallons. 5 gallons. 2 gallons. 1 gallon. Same mount of work. Efficient Nothing wrong with mini batches. I wish we had the option when i started. But micro batches are really not any solution to the problem of cost, time and volume. If 2 gallons is too much, being blunt here, find a new hobby. Cheers
Some folks are content to make 1- or 2-gallon batches. However, if saving time on brewday is important to you, making wort for a 5-gallon batch doesn't take 5x time over making a 1-gallon batch; maybe 1.25x, if that. You could split a 5-gallon batch however you want into separate fermentors and add different yeast and/or dry hops (where IPA’s get much of their oomph) to each fermentor and have (5) 1-gallon batches, (2) 2.5-gallon batches, and so on. That would give you feedback on different yeast/hops combinations.....although with the same grain bill.
I brew mostly 3 gallon batches because I like to experiment and have variety. I sometimes will brew a 1 gallon batch to test a new beer that I don't want a lot of. Whatever works for you!
There are a few people out there who brew single bottle batches. Too small for me, but you can do it if you want.
Despite all the comments about 1 gallon amounting to the same amount of work as a 5 gallon batch, one thing to consider is that doing 1 gallon experimental batches can all be easily done on a stove top - including mashing and boiling - and using common kitchen pots. Also no chillers are really necessary since the pot can be placed in a sink-full of cool water with ice cubes added. If your experiment is to determine the effect of using different hops, remember that when you later decide to make a five gallon batch, it's not quite as simple as multiplying the hop ingredients by five. The relative hop utilization is dependent on the amount of water used. Hop utilization calculations can help in this regard.
I have a one gallon kit. For me, it's mostly a space issue. I live in a small apartment with next to zero storage. Hopefully one day I can move up to 5 gallon batches, but for now, this is what I have to do. Additionally it's been good at teaching me the fundamentals without too much of a monetary or time investment in case the hobby ends up falling by the wayside.
I've been making 1 gallon batches for the past few months mainly due to storage issues and for experimentation. I'm still on the fence as to how long I'll keep doing this until reverting back to full scale. It is allot of fun and cuts your brew day / bottling day in half. It's also good to attempt styles I've never brewed which I can always scale up if they work out. Downside as people have noted already are things like taking samples for gravity readings etc. It is such a minimal amount of beer that you're eating in to. Also bear in mind you might get 1 gallon in to the fermenter but post fermentation it will be a little less. On my last batch which was an IPA, I lost more than expected to hop absorption leaving me a little short on what I got in to the fermenter. This was quite irritating and something you wouldn't really worry too much about on a bigger scale but it does matter on a smaller scale. If it's all the same to you though I'd say, give it a go and see how you get on! G
About 10 years ago, I recall someone used a coffee maker to brew a small batch of beer, more or less as a proof of concept. I don't recall the details, but the concept it proved to me is that small batches can be done.
Technically, as small as you would like. It would be absurd, and the cost of your time scales down with a bigger batch while cost of ingredients either stays the same or also scales down per bottle, depending out equipment,, ingredients, space, and planning, but you do you. Personally, I don't fuck with less than a 3 gallon batch.
I do one gallon batches all the time when I want to try new ingredients, efficiency be dammed! Sure it produces a small yield and the physics and chemistry will vary from doing a larger batch but it is a good place to start understanding what various ingredients have to offer. And if you brew something that sucks you only have to suffer through a six pack or so of it.
My main issue with really small batches, other than the small return for work put in, is that the impact of weight and volume measurement errors are amplified proportionally. That said, I've brewed batches from 1 gallon to 15 barrels, with a few sizes in between. For me, 5-ish gallons is the homebrewing sweet spot.
For those interested in 1 gallon batches, I recommend tracking down and checking out old Basic Brewing Video episodes. James and Steve have done a bunch of 1 gallon batches over the years, including both extract and all grain. They have tips and tricks for doing them as efficiently as possible, also. Cheers!
IF you really want, you could go smaller than 1 gallon batch, but TBH, that's as small as I care to go. If you have a bad bottle for whatever reason (didn't clean right?) there's another to sample. I would say it depends on your exact reasoning and what you hope to get out of making tiny batches. If you're looking for the effects of different mash bills, well, you'll have to go small. On the other hand, if you want different hops or yeast experiments, I would say mash larger, then break down to smaller boils or pitches. Question: are you doing all-grain or extract? that also can make a difference as to what is better and possibly the smallest efficient batch.
