I moved suddenly a few years ago and in the chaos that followed some brews didn't make it - this experiment among them. Although it did not survive and I was not able to see the originally intended comparison through to fruition, I want to note for posterity's sake that the Kveik Voss batch smelled absolutely stunning the last time it was seen alive.
I don't know if I can easily replicate the heat conditions in my new location but I may someday try to do a JAOM with Voss again because that seemed VERY promising.
3.5 lbs clover honey
1 large orange cut in 1/8ths
1 whole clove
1 small handful of raisins
1 stick of cinnamon
A pinch of nutmeg
Water to 1 gallon
3g yeast - one with Kveik Voss, one with bread yeast
Both batches started at OG 1.134
GoFerm by package instructions
Fermaid O: 2g
Fermaid K: 2.3g
DAP: 4.3g
While we're all cooking out here in Paso's summer heat, I decided I wanted to try throwing one of the hot-friendly Kveik yeasts in the backyard, like several other brewers have tried before.
I eventually settled on trying to find out what would happen with Joe's Ancient Orange Mead (JAOM) when given a hot ferment Kveik - but especially with such a ubiquitous recipe, I really needed to brew a second batch with the bread yeast used in the original instructions so I'd have a point of comparison.
I decided to use the bread yeast as originally instructed - without any rehydration or nutrients. Kveik Voss, however, I decided to give real nutrition. Albeit, that nutrition would be completely front-loaded, because I'll be out of town for a couple days early on in this ferment and unable to use a staggered nutrient schedule.
Although the Kveik batch will sit in the backyard summer heat wrapped in a towel (hopefully slightly better heat retention, especially overnight), the bread yeast version will sit inside, which is air-conditioned most of the time to about 74F.
07/22/2021 - brew day
Brew up two batches using the JAOM recipe listed above, pitch the bread yeast (dry) and the Kveik (rehydrated, plus nutrients), and we're off to the races. I was somewhat shocked to find out that both my batches started at the same OG, even though I did not make a single honey must and split it like I probably should have, I made two separate batches (cause it seemed easier to weigh out the honey that way, given I'm still trying to figure out the best way to weigh smaller amounts of honey out of the 2 gallon buckets).
08/13/2021 - gravity & ABV
1.033
13.26% ABV
1.022
14.70% ABV
In my opinion, odds are extremely high that both of these are done fermenting. I'm going to take the Kveik batch inside now so that if the gravity hasn't moved in a few days I can rack without disturbing the lees again like I did today.
09/22/2021 - 2 month mark (racking day by the recipe)
Marking this day out in advance so I don't have to check the recipe again for how long I'm supposed to wait lol
