Equipment and Software / Re: How much pressure?
« on: June 15, 2013, 01:54:09 PM »
To my knowledge Sankey kegs do not not have PRV.
It is the keg dispensing coupler that has it.
The keg couplers used for filling and cleaning do not have PRV.

14.9 Psi in pressure vessel is still a lot of pressure.
I tell you this from my own experience.
I was cleaning 15 BBL bright tank.
I was depressurizing it from bottom port.
When tank had about 1-2 psi pressure (by pressure gauge) I decided to open a 4" top port.
Lucky me that my head was not over the port because 4" end cap shot up like a bullet.
It is not a lot of fun when there is 4" piece of metal flying around you.

Needless to say I make sure that there is no pressure before I open any pressure vessel now.
That is true that Sanke couplers have a PRV, but we pressurise through the coupler. The guy who died with the plastic keg was using it on a sanke stand, which was set at a pressure that a sanke could take.

A little pressure over a large area equals a big force.

In addition, I did a Smoked Porter with grains smoked over crabapple, and it is too clean and one dimensional smoke. Pear is tasty. I have some mulberry that I have to use for either pork or malt (Or try both if enough wood is on hand). Oak is also good, used in Graetzer and Schlenkerlas eiche.

There are some smoking sites that give rough guidelines for woods to use. Nut and fruit trees are the usual suspects.

It is always good practice to take the safe route with pressure vessels.

What is the factor of safety on the design? Are there fail safes?  Sanke kegs are designed for 600 psi, Cornies say 130 psi, and we serve at say 10 psi which gives a safety factor of 60 and 13. Cornies and Sankes have PRVs also. We all know the amount of kegs that will be around, but we are familiar with those, so we don't even think of risks. I don't think much about thrones in the basement, or even the water heater in the basement (see Mythbusters).

Not trying to say it is all ok, I know of cases where fermenters have blown. What is the safety factor, back ups and certification? That is what I would ask.

I have never added anything to my water. I will try the gypsum an CaCl2 in the glass and see if that works.
Let us know the outcome of gypsum and CaCl2, please.

Beer Travel / Re: Chicago in October?
« on: June 15, 2013, 07:08:01 AM »
We go to Chicago a fair amount, so or favorites are.

The Map Room.
Haymarket. Pete Crowley's place.
The Pubican. More of an expensive Gastropub, but very good.
Sheffields for BBQ and American Craft beer.
Goose Island brewpubs are OK
Jake Melnicks is not too far and is OK.

The Rock Bottom at Grand used to be a good plan B when Pete Crowley was the brewer. Don't know now.

Piece is OK, but often their beers are not on but they have guest taps. Too crowded for us.
Local Option seemed expensive just after drinking at the Map Room. Very Metal!
Owen & Engine was OK. British Pub atmosphere.
Hopleaf had good beer, the food was a little lacking (too much time in Belgium makes one critical of the Frites).

The Lagunitas tap room my be open at the new Chicago brewery by then.

If you are staying at the Allegro(one we have stayed at), there is a Blue Line station in the Thompson Center. Red line is at State Street. Those 2 lines get you to most places.

A must for beer and food is the Girl and the Goat. Excellent food and a thoughtful beer list. You can eat at the communal tables early or at the bar without reservations, otherwise a very long wait. Now there is the Little Goat across the street with a simpler menu.

I had some soapy issues on my IPA and a smart person here on the 4M suggested addig a small amount of gypsum to the beer glass and it worked at scrubbing out much of the soap character. I now add gypsum to my mash for every IPA. Seems to have fixed the issue.

I wonder it it's the Calcium or Sulfate doing that? Or both?
If one had a soapy beer, and adding gypsum to the beer glass fixed it, one could try CaCl2 in another glass. If the second is fixed it is the Ca, if not fixed it is the SO4.

Any pressure vessel that hold over 14.9 psi have to be certified.
Do not play with fire.
+100.  An employee at Redhook brewery was killed last year by an over pressurized keg.
it was a plastic keg, just to be clear. Sanke kegs are designed for 600 psi.

You will have 3 of the best beer fueled days ever.

to be fair, parking in SF is redickulus.

true, I don't even think that Chicago or NY match SF for parking prices.
$35 for a half hour made me shake my head. Garage in midtown Manhattan. I was on foot.

Don't know hotel rates.

Dam spell check does that every time:). Also thanks for the insult on grammar "Jeffy"
I have been fighting with autocorrect also.

You sometimes see 150 ppm listed as an upper limit.

BTW - It is Sulfate, not sulfide.

Keep the kettle. You might start reducing first running a. You might start doing decoct ions, or cereal mashes. You might do a big batch and want to split the boil. You could use it as a grant if it has a valve.

Do not ask how many pots and kettles I have in the garage!

I always have some magnets around when pitching. A strong rare earth keeper magnet comes with the stir starter.

Similar to oxidation?
yes all early signs of oxidation.
