General Homebrew Discussion / Re: Another Acetaldehyde Question
« on: February 10, 2011, 08:17:02 AM »
I don't have much experience with lagers, but when I think acetaldehyde I think the fermentation wasn't quite finished.  That could be due to any number of things affecting the yeast's ability to finish in a "normal" amount of time.  Was the time you spent bringing the temp down in increments, in lieu of a longer d-rest?

That's generally true, but light lagers apparently are more prone to some other causes.  Some more details - this was brewery fresh yeast - approx 700mL of 3 day old slurry in 12gal of 1.050 OG wort.  Fermentation activity as judged by hydro, krausen and CO2 activity ceased at approx 12 days (1.012) which just shy of 1P per day - a good rate.  I let it go a few more days, then raised to d-rest for 4 days before beginning my crashing.

You can get by with a smaller starter is you have a stir plate, <2 Liters on mrmalty.  That is one thing that I now wouldn't do without.  Put it on your wish list.

+1 - and if you're relatively handy, you can build one for ~$30-$40!

General Homebrew Discussion / Another Acetaldehyde Question
« on: February 10, 2011, 07:44:49 AM »
Trying to pinpoint the cause of my recent bout of acetaldehyde in my Czech Pils.  In six years and thousands of gallons of beer, I've never experienced this flaw before, so it really has me awestruck, especially since I make a pils or dortmunder about every 4-5 batches. 

Granted, this beer is just shy of 6 weeks since brewdate and the green apple appears to be working its way out based on samplings...but I'm wondering if cold crashing my pils prior to kegging is the culprit???

I primaried for 3 weeks+ 5 days before kegging, but the last during the last 4 days, I brought the temp down from drest at 60-62 down to 40, dropping 5df each morning before work.  But crashing before kegging is not a regular practice for me - I usually don't get around to it and just keg at drest temp and then throw the kegs in the lager fridge.

Anyhow, I ferment in a 14.5 gal conical, and when I crash, I put sanitized foil with rubberband around the stopper so as not to suck back in the liquid in the airlock, but I got to thinking - did doing this with the pils cause the beer to suck in so much air that it caused oxidation which led to acetaldehyde, or am I fretting over 'green' beer that will lager away fine over the next month?

But I thought Frizzle Fry was much better than Sailing the Seas of Cheese.

Really?  I guess there's just something nolstalgic about 'Cheese for me - brings back memories of heading offshore at full throttle on my friend's dad's boat for deep sea fishing blasting "John the Fisherman" .

Unfortunately, a lot of my CDs got jacked by my first roommate in college, but I have some downloaded on itunes.

I always liked the EP that had the covers of Pink Floyd on it.

"Wynona's got herself a big brown beaver
And she shows it off to all her friends.
One day, you know, that beaver tried to leave her,
So she caged him up with cyclone fence.
Along came Lou with the old baboon
And said Recognize that smell?
Smells like seven layers,
That beaver eats Taco Bell. "

the first thing I thought when I saw this thread, was "ah, a fellow primus fan".

I have to think that's all this is about.

All Grain Brewing / Re: Vienna Lager water profile...
« on: February 04, 2011, 08:39:29 AM »

Is there any concern here? Is not the Ca a bit low for yeast health in this profile?


agreed - shouldn't it be over 50ppm at least?

awesome - not my next brew, but the one after is vienna - I'll be using the info here - thanks guys!

apologies lonnie, I'm hijacking here:


actually, maybe just adding a touch of gypsum is all I need:

Ca 23
Mg 4
HCO3 37
Na 21
Cl 70
SO4 36

doesn't wheat need to be mashed?

I'm pretty sure they are talking about a partial mash

Missed that part!  Carry on  ;)

like bluesman, I try to keep my house IPA on tap at all times.

I also brew either helles or pilsner throughout the year.

Marzen, porter, vienna, dunkel and witbier are 'seasonals'

Every June I brew 2 of either barleywine, RIS or Old Ale, whichever I am low on in conditioning.

then there's a half dozen or so of "i'm in the mood for" recipes.

Kegging and Bottling / Re: Acetaldehyde post bottling
« on: February 01, 2011, 08:18:50 PM »
very germain to a recent issue I noticed:

I racked my czech pils into a couple of kegs the weekend before last, and had an extra half gallon or so that did not fit so I put the remainder in a 2L soda bottle and force carbed.  However, in switching from the keg to soda bottle, I let a lot of splashing occur inside the bottle.

came back a day later to see how my green beer was doing, and boy was it ever green - acetaldehyde city.  Yet a toke off the keg revealed only a very faint hint, that i would expect from 2 day old light lager.

I make light lagers all the time, same yeast, and never have had this issue, but I also rarely taste the beer before a month lagering - point is - I think you will be just fine given some time (and I hope the faint note I got will go away as well).

Cheers!

damn - I started watching it last night at 11PM, but I made it all of 10 minutes or so into it and crashed.  It was good (what I saw of it).

I'm sure they will re-air it.

It was about 10:15 start to finish. <snip> Hope this one is worth it.

Oy, you can say that again!
