Yeast and Fermentation / Re: Re-using yeast
« on: July 20, 2015, 09:01:02 PM »
I got a call from the FBI after ordering sulfuric acid.  Despite the fact that the lab I was running was in a trailer, I never hear from the FBI again.

All Grain Brewing / Re: Water for an Oktoberfest?

There was an article in a recent Zymurgy about the water of Munich you might want to read.

Form this artice or a different one, it turns out the calcium needs for lager yeast are less than than ale yeasts so yes get rid of the gypsum as recommended by others and you probably don't need to bump up your calcium chloride to get to ~50 ppm calcium.

I'm not sure why you are worried about too much calcium given that the downside of sodium chloride, salty beer, is generally worse.

If your pH is 3.6 you have plenty of acidity to balance the residual sugar.

What will happen during the boil is somewhat unknown as lactic acid will also vaporize with the boiling water.  I suspect that the pH will go down due to the boil but it likely won't go back down to 3.6.

If you can get your hands on a gallon jug, I recommend splitting the beer between the jug and the ferementer and then pitch a large amount of yeast without doing the dilution and the boil.  You could heat the beer to pasteuriization temps if you want before pitching yeast.

I think anaerobic conditions initially are not essential but that may vary based on the specific strain.  Any reason why you just don't do the fermentation in a plastic bucket?

I think boiling the soured wort to be a waste.

Is the yeast count in "pure pitch" larger than the one in White Lab vials?

Yeast and Fermentation / Re: Accidental lacto infection; help needed

I don't take any particular precautions with kegs and lines that have dispensed sour beers, but I do disassemble and clean them between beers.  Also all my kegged beers are refrigerated.  So far no problems.

No need to throw the equipment away.  Keep them for future sours.

Yeast and Fermentation / Re: Lacto. Frustrations

The commercial lacto are pure strains which can have unusual traits like not producing CO2 or only eating glucose.  The lacto found on grains likely contain many strains and therefore I found produce CO2 and eat most sugars in wort.  When I grow my own lacto, I can really tell that it is just beginning to work when I see a pellicle - I don't purge the headspace with CO2.

You may want to try to taste (and spit out) the starter.

I do a big sour starter ~1/3-1/2 gallon per 5 gallon.  The wort drops below 4.5 with the pitch.

Option 2 is approximately what I do.  What I do differently is make a starter with DME at 1.020 instead of apple juice and I don't boil the wort or beer; I just pitch the ale yeast when the beer has cooled down.

Hop Growing / Re: My Columbus hops smell like an electrical fire!
« on: July 07, 2015, 07:19:57 AM »
Update:  I recently bought some Warrior hops.  They smell like an electrical fire to me too.  I can see why Warrior is used for bittering and not aroma.

Does anybody get else get electrical fire from Warrior?

General Homebrew Discussion / Re: Pineapple Juice in Primary?
« on: July 05, 2015, 08:25:13 PM »
ethyl butyrate smells like pineapple.  Butryric acid smells like vomit.  I'm a little skeptical of the idea that sacch will turn ethyl butryate into butyric acid, but I suppose it is possible.

Yeast and Fermentation / Re: Pedio for barrel aging

Thanks.  I'm going to try adding some maltodextrin and giving the barrel more time.
