thanks Misager
You answer put it into better simple perspective.
You use a seperate pumps to get the hot liquid to the mash tun, and the wort to the boil. Is this so that you can contoll the speed?
What is the optimal GPH for the pumps? Im in the aquarium hobby and have used lots of pump through the years some ranging from 20gph to 2000gph.
You don't even need to worry about that.  Just get the March 809 HS pumps,which are the standard pumps for homebrewers.
That is what I would say, Denny.

I also have water in both the mash tun and the HLT, added the night before.  The mash tun is preheated with a bucket heater, so that I just add the pre-crushed grain to begin the brewday early in the morning.  The HLT fire is lit a little before the step to mash out, so it will be at temp for the sparge.  Once the brew kettle has enough wort to cover the bottom, that burner gets lit.  These steps cut some idle time from the brewday.

All Grain Brewing / Re: Tannins
« on: May 22, 2011, 05:04:06 PM »
"Tannins" is a pretty broad class of compounds. Some tannins are a normal part of beer flavor and body. Excessive tannins could be perceived as astringent.

You definitely run a risk of overextracting tannins when either your sparge temp is too high, or if your sparge temp is lower but your pH is too high.

Get the mash pH set in the desired range 5.2 -5.6 or so.

Adjust the sparge water to the same pH using Phosphoric Acid (what I use) or Lactic Acid.

Then there are no worries.

 It's a shame you won't be trying the ribs.

Austin and some of the towns in the area are the home of brisket, but it is a shame you won't be eating that.

We always like the Gingerman if we are downtown.  Really like the Live Oak beers and some from Real Ale. 

Several new brewpubs have opened since we were there last time, so I can't report on those with any knowledge.

I think maybe we need to read it with a sense of humor, I'm sure it was intended as a joke.  And also remember when picking out your six pack who gave people a free chance to go to beer camp.  Just sayin'. ;)

It's kind of funny to me though, that whoever this is makes very good points in some answers about the difference between home and pro brewing, and then in other questions completely ignores that difference.  For example, the autolysis question - the conditions at the bottom of a giant tank are a lot different than in the bottom of a 5 gallon carboy.

Not the same person responding to all questions?

The same guy had predicted that the world would end in 1994.  Had a math error. 

Having lived through many end of the world predictions, I am not too concerned.  The whole Y2K stuff had more veracity than this.

All Grain Brewing / Re: Rice hull question
« on: May 20, 2011, 05:01:22 AM »
When one of the mashes of the 'Old Cantankerous" stuck, the second got a dose of rice hulls.  About half a bale of rice hulls went directly in the mash for 10 barrels of beer.  They had those on hand, for some reason.

Mario Andretti was the spokesman for STP with his Indy car. No?

King Richard

That depends on the time and place of your reference.

I remember Andy Granatelli, and Mario won in Andy's car in 1969 after the turbine cars failed the 2 previous years.

Beer Travel / Re: Arkansas, Chicago, NYC

Last time we were in Chicago we went to the Map Room (a favorite), Revolution Brewing (very good), and Haymarket ( this one had some excellent beers and food, but what is up with all of the big screens?).

Hopleaf is good, but pretty far north.  My wife does not vote for Piece, as the pizza is not that good and the best beers are always out when we are there.

Owen and Engine has gotten some good write ups.

We enjoyed Publican for a lunch, and it is along the Gastropub lines, but more Gastro than Pub.

Some of you might remember this one too. "You can trust your car to the man who wears the star. The big red TEXACO Star." And of course a gallon of gas for a quarter.

Cheers!!!

Yeah I bought gas for a quarter a gallon.  Those  were often silver quarters, which I read recently would buy 2 gallons of gas at the price of silver and gas recently.

Bought gas for $3.82 in Kalamazoo this AM, and it is $3.81 now back home.

Hydrogen is an attractive fuel.  One drawback is that it either has to be stored in cryogenic tanks if liquid like the shuttle, or stored at high pressure to get the energy density one wants.  The fuel cell vehicle I drove had 3 tanks to store the hydrogen at 10,000 PSI.  They had to allow for expansion around the tanks as they grew considerably when filled.  The range was only about 200 miles, if I remember correctly.

Hydrogen can also be burned in an IC engine, which was what one BMW show vehicle did.  Or you can burn it in a rocket, like the shuttle main engines, or the upper stages of the Apollo rockets, the J2 engines.

General Homebrew Discussion / Re: Benefits of a 90 minute boil?
« on: May 17, 2011, 05:27:15 AM »
Caramelization happens at elevated temps.  This only happens when you have boiled off most of the water.  It starts at 230F and must go higher for some of the larger sugar chains, > 300F.

So if you boil down first runnings in the kettle or a pan you can caramalize.  If you boil all the wort at ~212F, you don't caramelize.  Are there elevated temps at the metal-liquid interface that can cause small amounts of caramelization?  That I don't know.

This scheme would collapse if the "Man" was not keeping the water powered cars off of the market.


Had some one tell me that at Big Brew.  Really.   8)

Well... fuel cells

hydrogen + oxygen → fuel cell → electricity + water

and

water + electricity → hydrogen + oxygen

Shuttle Endeavor is using the first part to generate electricty and potable water on orbit as I write this.
Electricity generated by solar panels can store energy as hydrogen - to be used to generate electricty via fuel cells when there is no light (at will).  

Or by direct combustion of the hydrogen and oxygen.
I had mentioned to the guy that I actually have driven a fuel cell vehicle.  Really, I have driven one.

He was talking about the tank of water and some gizmos to turn the water into fuel (i.e. hydrogen).  The probelm with this is water has been already "burned".  There are some laws of thermodynamices that say what the guy was talking about is essentially Perpetual Motion.  The conversation was along the lines of something for nothing.  The supposed inventor had guys show up on his door step in black suits and sunglasses.

What you talk about will work, as the energy comes from the solar panels. That does not violate any laws of nature.

Edit - this was fill your tank with water, all of mankind's problems solved.  Nothing about the source of energy.  Google "water powered cars".  It is entertaining.

"Speculators are driving up gas prices!"

"Greedy Big Oil is driving up gas prices!"

I'm so confused!

All Grain Brewing / Re: Crystal malt and corn
« on: May 16, 2011, 11:12:13 AM »
If you look at cream ales as an ale breweries take on a pislner, you want to keep the color light and the finish somewhat dry.  The one I made uses some carapils and flaked barley for the body and creamyness.  A little 2 row and corn are the rest of the grain bill.
