The Dirty Yeast

stoutmaker

Took advantage of the weird winter warm up here in Green Bay. This time of year my basement is usually around 45F. Which is a bit too cold for a good lager ferment. But this winter it’s been sitting at 52. Perfect.

So, from a followers suggestion I brewed up a Kolsch. It was a good choice for a couple reasons. First was the temps. I could still brew while my heat box was full. Second because I am currently on a SmasH beer kick and third because I can use this beer for the Germanfest contest in Milwaukee.

Very simple recipe here.

  • 8lbs pilsner
  • 1oz Mt Hood
  • S-33 yeast

I have used the S-33 yeast before, but do not remember it being as “dirty” as this.

This is over week later after pitch. But I’m not worried about it at all. I’ve seen much much dirtier looking yeast. (Like the Kveik. That looked like I fermented a mud wrestling pit)

It will clear. You can tell from the second pic that it already is. Look at the bottom half compared to the top half. I will give it a 2 more weeks to drop and then get it moved to keg. Once in keg it’s easier to move to warm and back to the fridge to condition.

Next week I will be doing a some work on the wine side of things. And maybe another Mead?? I dunno.

Stay tuned.

Hot day lager brew

Took a road trip to John’s house for a 10 gallon split batch of Mexican Lager. Started in the morning before the heat got up there.

Almost forgot the recipe

10 gallons yet unnamed Mexican Lager

  • 11 lbs Vienna
  • 3 lbs pilsner
  • .75 lb 60L crystal
  • 4 lbs flaked corn
  • 2oz Tettnang @60 (see below)
  • .5 oz saaaaaz @30 (see below)
  • 34/70 lager yeast

(the recipe called for only the 2oz of 6% Tettnang hops, but the ones we had were only 3.7% so we threw in the extra 7% Saaaz to make up a few of the IBU, plus will add some flavor at the 30 mark)

Oh,, this was also going to be a taste experiment. John is fermenting as a usual lager would call for.  And I’m going to use the same 34/70 yeast in my half, but just gonna let it roll at my basement temp of 63 degrees and keg it up at my usual 4 weeks.

Bad Yeast

Last month I brewed up what I was calling the “work beer”

Just a simple little beer with 2 row, flaked oats and crystal with a pack of Montueka hops.

Normally a simple little beer like this gets brewed and drank with out much attention. But this one had a few issues.

The first thing funny with it was something that had already mentioned in it’s original post. The hops were full of junk. Yea I’ve had hop packs with the occasional leaf in it before, but this was beyond that. But I didnt get a picture of it, and didn’t really have anything to do with the second problem.

I had gotten some outdated liquid yeast from the shop to use. Done this several times before and no problems.

Now when I say out of date, I’m not talking a year or anything.. this was just a couple of weeks past date.

Because it’s just a low grav 3 gallon I did not do a starter, I just pitched the whole vial as usual.

After 2 days of not a bubble or that normal yeast krausen layer I removed the airlock to get a quick sample to see what was going on.

I was immediately met with the stench of something between wet siliage and dead nightcrawlers. Obviously something is not right there. The sample shows no drop in grav so I give it a slight stir and let it go till the next day.

Next day still nadda. So I pitch a packet of 05. The 3 day lag kinda worries me.. but still think it’s gonna be ok.

After about 2 days it should be up and rolling fairly well,, but it’s not.

Yes there is some fermenting action happening.. but very slow. And a inch thick layer of what looks like vasaline. Not your normal krausen. I again open the top and get the same dead nightcrawlers smell.

These pics don’t really show what it truely looks like. The pics look fairly normal, or close to normal.. but no way. It was a gross gloopy clump.

But it was doing “something”. So I let it go. After about 2 days the thing started to grow “legs” or something. Long stringy things hanging down from top to bottom.


This pic was when it just started, and this makes it look almost fine,, but got worse pretty damn fast. No real fermenting action, just growing stringy legs and was starting ooze an oil slick on top.

I did wait for about 3 weeks. But it smelled so bad and just kept lookin like it was ready to crawl out of the carboy.. I just dumped it.

I dont think it was a sanitation thing. It didnt act like a good ol infection.. I think the yeast was just dead, spoiled and decomposing. And I don’t think making a starter would have “helped”. Sure it would have saved this batch because I would have seen the yeast was junk, but it wouldn’t have saved that yeast.

What ever died in that vial must really been bad, if it almost killed of the 05 yeast as well.

Welp can’t win them all. The next batch in the same carboy is already under way. No problems.

Its a Soriachi Ace hopped so hoping to get some pickle action out of it.
