5g Lager w/ 1 pack of yeast?
Hi All, I bought a brewer's best "European Bock" kit. For a 5gal. batch they provide one 12g package of Brewferm Lager yeast. I just built a small ferm chamber so I can keep it at the right temp (this will be my first lager attempt). Should I rehydrate the yeast as the packet instructs and pitch, or would you make a 2L starter first (I have a stirplate). I've read you should pitch a lot of yeast for a lager, and 12g of dry yeast doesn't seem like enough to lager a 1.064 beer. However, I've read here you really shouldn't make a starter with dry yeast since it's packaged at the height of it's viability and a starter could "weaken" the yeast. What do you think?

I don't make a starter when using dry yeast. I'd rehydrate and pitch.

the respected mr malty yeast calculator says 2.3 packs dry yeast for lager??? FWIW I think I would get another pack of yeast especially if you are intending to ferment at the cooler end of the range.


or rather than making a starter...make a 2 gal batch and pitch that slurry into the 5 gal batch...bam!

I do realize this isn't really an option as you are kit brewing. Maybe contact brewferm and ask them WTF?

I'd make a starter, 2L is probably enough as that's all I ever make. Some will say it is not.

Making lagers has taught me one thing. They need a metric ton of yeast. Take your calculated yeast value, then double it. Then maybe double it again just for fun.

Fermenting over 1060 in the lower 50 degree range requires your body weight in yeast.

Didn't I say that somebody would say it wasn't enough!

Crap, thanks for the replies. I had a feeling you guys would say that. I brewed it and rehydrated the dinky "sachet" of yeast per the instructions and pitched it. I guess we'll see what happens. I can tell you nothing's happening yet. I would have made a starter if I had more time....and I was more patient.

What temp did you pitch at?

beerman0001 09-30-2012 10:17 AM

And yes you can make a starter out of your dry yeast you would have needed to make a 3l for this lager. It is just sooo much easier to just buy to packs of dry rehydrate and pitch.

Thanks all for the replies.

It got to mid 60's I'd say,pitched, then threw it in my ferm chanber at like 55.

It's been 2 days since I pitched and I'm seeing almost no activity. Maybe a bubble every minute or more. I'm thinking I should buy some more dry yeast and pitch it, what do you think? 2 packages? Should I re-oxygenate, or is there still enough Oxygen in there?
