Lutra in a pseudo-lager

[DJL531]

Making a maibock using Lutra. Og is 1.066 and after 9 days we are down to 1.022 and still bubbling. Temp at night gets to 74 and maybe 80 during the day.

What I mean to as if it normal for Lutra to take off like a rocket and even with a steady bubble be going this long? This was an extract brew, not that that should make a difference.

This is 5 days in for a pseudo Pilsner with lutra I fermenter at 71. Cold crashing now because I don’t want it to drop lower but I do think it’s done.

Well, my Lutra got stuck and I have no idea why. I made a US-05 starter and added it in there and it slowly started going again. Almost 4 weeks in I got to the FG I was after, or close to it, and bottled it 4 days ago. 3 days bottle conditioned and it has some fizz and no head, but tastes pretty good. I have another pack of Lutra I will use again, but not sure on what just yet.

What are you using to take your gravity reading?

What are you using to take your gravity reading?

I have a glass hydrometer and I temperature correct the readings.
I don't have my book with me but I noted all the readings I did. I must have checked it 7 or 8 times.

 

[Dgallo]

Just making sure it was a hydrometer, countless times I’ve seen people post about stalked fermentation right around 1.022-1.026 but they were taking readings with a refractometer.

Also Did you using yeast nutrients at all? Lutra seems to have have big nutritional needs but I wouldn’t think that would affect attenuation so drastically.

If there are fermentable left, the us05 will surely take care of them

 

[DJL531]

I did not put in nutrients, but in 12 hours the top was pushed off the fermentor so I thought all was healthy and strong. I did add them to the US05 starter to make sure it was as healthy as it could get.

That is odd. This almost seems like not a yeast issue, maybe a mash issue... I've brewed with Lutra a fair bit an it always takes off in about 30 minutes and finishes pretty dry (1.008-1.012) no matter the gravity and no o2 added. I usually always pitched warm and let it fall to whatever room temp is.

I have to agree. Everything I have read says this fires up and runs like crazy. I didn't make note of this, but I use RO water on nearly all my brews over the last 8+ months. I'm in Baton Rouge and we have pretty soft water with a high sodium content. Looking back at other Kveik yeasts I have used, I never had this problem and most, even those that took 36+ hours to get going (yes, WTF???) finished in 3 days after that and I bottled on day 7. I have another pack of Lutra that will be used in a month or two for a pseudo-lager I am devising. We shall see what that does...

Oh, one more thing and I don't know if this matters. When I took the OG it was crazy high. I took the sample from the tap at the bottom of the carboy. It made no sense. Then I realized I didn't stir the wort after adding the extra water to make it up to 5 gallons. This was an all extract brew with a 3-3.5 gallon pre-boil volume. I forgot all about it when the the next morning I had the yeast 'explosion' and figured it was grinding through all 5 gallons . Maybe it didn't.

 

[beersk]

Hmm Hard to say. I also use Wyeast yeast nutrient. That might make a difference, maybe not. But I always use it regardless. With any of the kveiks, I don't oxygenate. They just don't need it.

<awesome beer pic snipped>

5 days and it's that clear? Wowza. Any tips you can provide? SMaSH Pils?

Nicely done.

I tried 2 lager-like beers with this yeast and they both took a while to clean up flavor-wise and in appearance in the keg. I had high hopes for Lutra but I ended up going back to easy to use lager strains.

Here’s one of those beers.

What are those easy to use lager strains in you opinion?

Augustiner, S23, 34/70 & S189

Those are the ones I’ve had the easiest time with - I don’t have temp control but live in New England and my basement gets between 50-60 in winter and then I lager in the garage in a keg which is 35-45.

I only do lagers in winter, so I was excited for Lutra, but…

 

[Dgallo]

34/70 is so easy. Just use a higher pitch count and keep it sub 60. Nothing more than that

I fermented at 71 it was 9 pounds pils .5 carapils .5 Vienna and I really didn’t do anything it was in an anvil brew bucket and just looked that way when I took a sample.

Not pleased about name being used for yeast
