lager question

Postby dartedplus » Mon Dec 16, 2002 5:29 pm

With this latest batch being my first lager, I have a question...or two.

First, my laundry...errrr....lager room is at a cool 49*. Does a lager have a slower, less active primary ferment than an ale??? I have a bubble every 3 seconds.
Second, since it is a bottom fermenting yeast, when I leave behind all the schmeg when I transfer, will I be leaving too much viable and necessary yeast behind, or will the live active yeast be in solution????

curious

Lager answer (maybe) ...

Ed,

Greetings, I recall that 45F is the optimum temp. for most lager yeasts, I say most , there are exceptions. I live in SC, so in the heat of the summer our house stays at around 68-70 (centrl air) and I don't have access to a chest freezer with temp controller (yet anyway, working on it) I ferment my lagers at room temp with no adverse effects. I do know that in the winter when my garage stays at a comfy (lager temp) of 45-50F I put my carboy out there and the fermentation does slow, so I think you are on the right track.

All in all I don't get too concerned that my lager yeast is at room temp, Good luck and let me know how you make out OK. "Don't worry have a home brew".
Regards,

Paul.

lager fermentation...

Postby HomeBrew » Tue Dec 17, 2002 3:04 am

I haven't made a great many beers using a lager yeast, but I do believe that they ferment at a slower rate than an ale yeast. Whether this is primarily a phenotype of the yeast strain or a consequence of the colder temperature (would an ale yeast be that much more vigorously evolving CO2 at 49F?) I don't know; I suspect it's a combination of the two.

I assume you're asking if you'll carry over enough yeast during transfer to a secondary for conditioning? Or even during transfer for bottling? The answer is yes. Short of filtering the beer, it's extremely difficult *not* to carry over adequate yeast during any transfer stage, even if it's bottom fermenting.

Good luck!

lager/steam beer

Postby fitz » Thu Dec 19, 2002 5:10 am

lager yeast does not have to brew at lower temps.
I try to use lager yeast in the winter, and ale yeast when the temps are warmer to "try" to keep the yeasts at their optimal temps. However,there used to be a very popular style, and with homebrewing, is making a comeback, called steam beer. Californians used to brew lager beers at ale temps, because they didn't have refrigeration, and the brewmasters were from origins that always brewed lagers. They found they liked this version, and so did many others. I myself like beers of all shapes and sizes, especially european and homebrews.
