1 yr old Kveik yeast

[Geoff S]

Been wanting to try Kveik yeast as keeping wort temps down is a pain in the butt, bought some GigaYeast 134 around Dec 19 & promptly forgot about it, pulled it out of the fridge on the 1st this year thinking "too long, kaput" but stuck it in a sanatised bottle with 130g of dry malt extract, shake & put in cupboard, nothing for 3 days then off she went, so, 2 days later a can of IPA, 1.5kg of LDM, a though mixing in coldish water, in went the shaken yeast starter, next morning it's humming away quite nicely, the OG is 1045 & tasted really good, will see how this turns out & will store the tubby stuff for later.

Will be fine. Yeast is hardy stuff you can freeze it and it will kick back to activity.

There's been developments! Came out on day 3. no activity, OK, I'll leave it another day then do a test & see if it's worth bottling, heard Kveik can be ready after 3 days, so, today, day 4 gave it a hydrometer test, very bubbly, not liking & gravity at 1020, liking even less, have had colder temps, 25deg, so this could be why it has stalled, googled up 'stalled brews' & a couple of ideas came up, only one I could use though, 'swirl the wort' did that & back in business! Airlock is off & running, hotter temps are forecast so they might help, but swirling the wort might work if your brew stalls.

Things I'm taking away from this, if the gravity test is fizzy & bubbly the brew could go longer even if the gravity is at 1010-1012 it might drop lower with a bit more time, it might explain bottle bombs even though you have done everything right. I usually leave brews to go 2 weeks before bottling, but that's just me, this Kveik is a new ball game to experiment with.

Well, this has been interesting, it's day 15 & sg is down to 1000, I've testing & retesting each sg test to make sure bubbles are not interfering with the test & it's slowly been coming down, bottling tomorrow, it's been tasting great, I could drink it straight from the fermenter, but that might be just me.

Let us know how it goes GS - sounds good - be interested to see how the Kveik performed mate. Cheers ; )

It's been a week since bottling, had to give it a go, usually when I drink a 7 day bottle I get 'a bit green but good' this bottle was 'Yeah! not bad!' give 'em another week & see how it is, so far the Kveik yeast has been a winner, more experimenting(and drinking)needed.
