Lager yeast
« on: November 28, 2018, 04:43:17 PM »
Hey everyone,

Brewing a bohemian pilsner at the moment. Pitched a yeast starter I made into it on the 17th. Its coming up on 2 weeks in the fermentation fridge now and its only dropped just over a point in gravity. I haven't much experience with lagers but I thought it would have dropped more by now. Does anyone have any insight into this?

Saflager s-23
OG 1.052
Current gravity 1.038
Kept at 10C

Sorry for the obvious question but what temp are you fermenting at?

Whoops didn't see temp.. I'd say a touch low at 10c try 12
As Dempsey said it should be further along. Raise the temperature and check your fridge temp

If it's a lager yeast 10 is more than high enough. That sounds like it's not even fermenting. Bad yeast pitch?

Its STC controlled and 10C is correct. I made a good starter or a least I thought I did. Would it be of any benefit to add a sachet of the same yeast this late in the game?

What have you to lose, pitch another pack but Up the temp to 12. Or try 34/70 yeast at 12c. I know 10c is in the range but do up it to 12.

Why did you make a starter with dry yeast? I'd chuck another 2 sachets in to get it moving.
Also how are you measuring gravity. A spectrometer perhaps? If so that's not straight forward. Take one with a hydrometer

You need alot of yeast for a lager, 3 times that of an Ale so you may also have underpitched. Add more yeast and see if you get an improvement

I had made a starter using dry yeast, I had a good amount of slurry going in. Never got into spectrometers, Ive always used hydrometers.

I added another 11g pack of the same yeast again this evening. Im hoping this will improve it

Just a follow up question but how did this pan out in the end.
