    Big reason I'm not liking the new Big Mouth Blubbers for aging... too much head space in the big necks. had a couple batches get nasty bacteria on top. Hopping to save them with good 4x meta solution

    I think it alos has to do with wall thickness of the glass

    No joke, I use to top mine right up to the bottom of the cork, or within a 1" of it. Not anymore. With heat they expand and will rise up into your airlock.

    Reminds me of an SAT math question! Lol.

    Carboy B is the largest
    Carboys A&C about -6oz.
    Carboy D is the runt at -10oz
    Final answer!

    I’ve got a 5gal that’s more than 5.3gal actual.
    A 6.5 closer to 7
    And I have x4 54L demi’s which vary but the real drag is one of em has a larger bunghole than the others requiring a different sized stopper. It is what it is tho. Fughetaboutit.

    My LHBS supplier has their own direct glassmaker source. Take the good with the bad. Dirt cheap. But sizes tend to vary.

    I agree AJMASSA - Makes my brain hurt figuring it out.
    And now that runt Carboy 'D' is the next one I have to rack into in a few days. Going to be interesting as the remaining 3 gallon batches cycling through the racking process should have virtually no sediment other than a dusting on the bottom. Time to get my smaller 12, 16, and 20 oz containers cleaned and ready for use.
    Before I rack again I'm going to do a real measurement of that carboy and I think I do have another spare that I should check as well.

    Yeah the bung fits are a real headache too. I keep splitting the small plastic ones that are supposed to fit my screw-top 1 gallon / 4 liter carboys. Need to find smaller bungs for those. So far the ones I've tried are too large and pop back out.

    I have three 6 gallon carboys and all three are different. What I did was put white electrical tape on the side of each of them and fill them a gallon at a time and mark the tape at each gallon poured. some people do etch the glass with markings.
