1.75 vs 2.5 keg

[hooterjbrew]

I really like doing 1gal small batch brews since I can do them in the kitchen and I can make several at a time and in return they don't take up much room. I would rather keg than bottle as well so here is my dilemma...Found a website that has 1.75 gallon kegs with same size corny lids and ball lock posts, for the same price I can get a 2.5 gallon ball lock keg.





Does anyone have any experience with the 1.75gal keg?


Should I take the 2.5 over the 1.75 for 1 gallon batches in case I want to keg half of a 5gal batch?


Is there an issue with Kegging 1gallon of beer in a 2.5gal keg?





The size of the kegs are only 3" different so Im not to concerned with that aspect of the comparison. Some experienced knowledge would be great!!

Had this posted in bottling/kegging with no feedback.

I personally would go with 2.5 just for the sake of having more room if you want to brew bigger batch. 1 g in a 2.5g keg is fine IMO as long as you purge all the air out right away. I just kegged 1g in my 5g keg and its carbing up just fine

No experience but 2.5 seems more logical. You would be purring the head space with co2 either way so the 2.5 as you mentioned would be perfect to split 5 gallon batches.

I have a few of the 3 gallon kegs. I would also go with the 2.5 over the 1.75, simply for economy of scale reasons. With the 1.75 you'll be getting at the absolute most 14 pints, but realistically more like 12 (after discarding some sediment, testing carb levels). And cleaning, sanitizing, filling, and carbing the smaller kegs will take just as long as the larger ones.

I have a 1.75 I use for take out to parties and such. It fits in a modest sized soft sided cooler. I also have 4 2.5g. I like them both for different reasons. if the size doesn't matter, get the 2.5g.

Only down side is you'll use more CO2, but not that big a deal.

I'd go 2.5gal. You can always put less in, but the amount of effort to step up your 1gal batch to a 2gal isn't difficult at all and will likely take the same amount of time. Once you find a recipe you like, it's nice to have a little extra on tap when you're ready.

Height difference between the two is minimal, but significant if you're putting it in your kitchen fridge. Something to keep an eye on. I wouldn't worry about excessive headspace for the CO2 for carbonation, the amount of CO2 won't be a game stopper, IMO.

Where did you get your 1.75? PM me if we aren't allowed to advertise such (noob). And how good has the quality been?

Adventures in Homebrewing has very inexpensive 3 gallon pin locks, too.
