Maybe mash 8 gallons, split into 2 = 4 gallons per carboy
I can dedicate a fridge to this. But I don't have it set up yet... the BYO article didn't mention this !
But even then, high gravity fermentations can become explosive. 6 gallons of beer plus 2 x 1 pint of yeast slurries in a 6.5 gallon bucket does not leave enough headroom.
Agreed !
Split over 2 buckets or use a larger (wine) bucket, they're around 8 gallons, perhaps?
The wine buckets are around 10 gallons. I hate them because they are so leaky, air wise.
I currently have:
3 x 6 gallon Better Bottles. I dislike them because they flex if you move them and they are hard to clean through the narrow opening. But they work.
2 x 3 gallon Better Bottles. They don't flex as much as the 6 gallon version, but still hard to clean.
2 x 7 gallon Bigmouth fermentors. They flex, but at least you can get inside to clean them.
Several 1/4 barrel (7.75 gallon) Sanke kegs. I'm about to weld a 4" TC ports on them so they can be used as fermentors.
Several 1/2 barrel (15.5 gallon) Sanke kegs. See above.
I could also borrow 5 gallon carboys from friends.
How much does headspace matter when fermenting a big beer like this ?
I wonder why the recipe directions don't mention the 2nd yeast or the possible need for feeding.
If I/we brew this big wort, how do you feed it ? Or do you think that Anchorage Brewing starts with a smaller wort and then feeds it ?
It's not impossible to ferment a 1.164 wort from the get go, I've had wonderful RISs in that range, but it's surely pushing it, and the risk of it stalling is always looming.
I'm here to learn. Tell me more. What yeast did you use ?
Now if you're going to feed this, you can start out somewhat smaller as you'll be adding more wort (and nutrients) toward the end. But you need to plan for that, it's a different process.
Feed it wort ? Brew more every week ? Can wort in a sterile jar ? I have a pressure cooker and I canned wort for starters way back when...
Also, I'd try very hard to prevent oxidation during the feeding phase. Whenever taking samples and adding wort, I'd leave the lid on, and use a 2nd access hole, so you can stream CO2 in while tinkering with the samples and feeding. But that's me.
I thought oxidation wasn't an issue while yeast were actively fermenting ? I thought they would gobble up any excess oxygen that was available ? Isn't that one advantage to bottle conditioning over forced carbination ? Though this beer will need to be force carbinated.
I could easily weld or solder extra ports on the Sanke kegs. Would also help for pushing the final product into a serving keg. But... you can't see what is going on inside.
Sounds like this will take more prep than I was anticipating. Also sounds like this is a great learning opportunity.
