Ingredients / Re: Sourcing Phosphoric Acid

Lactic Acid:
Typical Concentrations in Beer:
0.2-1.5 mg/L

Perception Threshold (in neutral solution):
0.04 mg/L

So, 0.2-1.5 ppm would be what is normal in beer anyway - perception would depend on the base beer. For comparison, I dosed Coors Light at a rate of 1.5 mg/L lactic acid in an off flavors presentation I did and about 50% of our club members picked it out correctly.

This is good to know, thanks Amanda. Maybe ill douse a yuengling to tone my taste buds.

I also added a pump bleeder valve to the chilling system yesterday. That thing is sweet.

I was thinking about adding bleed valves to my pumps, wanna take pics of how you did it?  I have real problems waiting for my pump to push water all the way threw 50Ft of herms and then another 20ft of hosing.  Bleed valve would probably fix the problem.

Anyone have any experience with this product?  I used some in my last APA batch and i am fairly sure it made it water and insipid.  I dont have any non-clarity ferm-ed APA of the same batch ATM, but will do a side by side when possible.

Well, our brew day went OK today, but there are still a couple of things we struggled with.

First, does anyone have suggestions for getting wort pitching temp down faster? We have a wort chiller for our 10-gallon kettle, but it still takes over an hour to get from boiling to below 80 degrees, and I'm getting concerned that we're risking our luck when it comes to infection.

Secondly, we had a lot of hop additions (including a 2 oz Mosaic addition with 1 minute left in the boil), and we clogged the filter at the bottom of our kettle. The most-frustrating part of that was the fact that we were forced to siphon, and then left a large amount of hops behind in the trub/sludge at the bottom. Does anyone have any best practices here as it relates to adding hops at the end of a boil, or even experience with large hop additions, and keeping them from causing a stuck transfer process?


#1 can be a tricky problem, because if your source water is hot or you dont use a pump you are stuck at the whims of gravity.  Having water flow through the chiller faster will help but in the end with a immersion i always just chilled for about 15 minutes(which got my wort to 85-90 F, and then transferred to my bucket and pitched the next day.  As long as your sanitation practices are righteous you should have no infection issues with this method.

#2  Hop Spider.  You can make one with a PVC collar and a nylon bag, or just buy a SS one. I have this one for my 5G system.  Zachs products are awesome.  Id buy the biggest one possible.  You put the hops int he spider and when the boil is over just pull the entire spider out.  No more hops sticking up your valve!

Results of the First Brew on the new 1BBL system

All MO Pale Ale fermented with a French Ale strain.

all the hops are from a local farm.  Tastes kind of dank and the hops arnt in your face.  The head doesnt persist  sadly.  Either way its rather drinkable

An old friend who brewed the best Oktoberfest I have ever had in my life swore he had the best results lagering in a keg when the keg was in the fridge horizontally.

The keg horizontally makes a lot of sense, less distance for all the crap to fall out.  The problem would be the second you move the keg its all gonna go back in to suspension though....

Do you want to ferment it in a corny or cold condition it?

4 Wires makes me think its 240V not 120V.  The green attached to the housing is def the ground.  If i where you id find a 3 wire cord, hook the ground up and randomly start touching the hots to the wires and see if you can map out which is which.


The cubes most readily available to me are Hungarian.  Ive heard hungarian Oak is the prefered oak for vintners but is very expensive.  Ill have to give them a try the next time i brew a batch of oaked beer and do chips in the other.  See which we prefer!

Correct, and it sounds like a gong when it bows back and forth.

While I am a huge fan of the restaurant-grade made in America BP-series Polar Ware kettles with factory welded fittings (see page #2 of this PDF:, I am not a fan of the economy line.  You can do much better for the money.  Bru-Gear offers a nice kettle at that price point.

What do you not like about their economy line?

YOu get what you pay for.  In the PW economy live i have seen a lot of thin bottomed pots that oilcan like a sonofagun.  Id prefer to not have a drum for a pot personally.
