Equipment and Software / Re: Stainless steel vs aluminum kettle?
« on: March 06, 2012, 11:03:03 AM »
There is another important factor in the selection of material type for kettles and that is heat transfer coefficient. 

Depending on how you are heating your wort and kettle, that should be an important factor.  I formerly heated my kettle on a gas burner.  An aluminum kettle has a far better coefficient of heat transfer than stainless steel.  That means that you will heat your wort quicker in a aluminum kettle. 

Martin, I don't agree with this.  If you look at the Overall Heat Transfer Coefficient the conductivity of the metal is the lowest resistance in the circuit.  If you heat with fire, the gas to metal has the highest resistance, the liquid is the next highest.  If you run the numbers, there is negligable time difference.  I actualy ran a test for 2 pats I had that were the same size and geometry. One was SS and the other was AL.  The SS kettle got to a boil faster!  I expected the AL to be a little faster.  I think it was due to more bubbles in the AL acting as insulators (rougher finish) and more loss of heat through the side walls in the AL.

Aluminum will spread the heat better so you avoid hot spots. 

This explains what I am talking about.  The example is very good.

Drew's idea looks to be a good one.

Everyone needs to think about the work that goes into judging 750 beers.  There was a local competition this last weekend that had 1034 entries.  There were 5 sessions over 3 days.  It was a lot of work, but a lot of fun also. The judges also came from Ohio, Indiana, and Illinois in fair numbers.  There was one guy each from Texas, and California (featured speaker John Palmer).

You will not get the participation from all of the states in the area if there are other judging center close by.  I am thinking of going down to Indianapolis to help with the judging, just need to sign up and do it.

Look on pages 36-37. Yes it is a Northen Brewer derivative. It does have a minty aroma in some beers.  I have used it in the past.  A local pub uses it in many of their beers, sometimes for bittering too.

The Pub / Re: AHA Pub Discount
« on: March 05, 2012, 07:18:39 PM »
How does one go about getting their local brewery on the discount program?  My local(ist) brewery has started making some pretty good beers.  I've been buying growlers there lately for home consumption.  They only have a tasting room with beers to go.  No food.  They have a BA member sticker in their window.  It would be nice to get a buck or two off per growler as an AHA member.  Is there some place I can direct them to look for more info?  The other two breweries on the island already participate.  It would be nice to have all three onboard.

Don't know about Hawaii, but a lot of states don't allow discounting the alcohol.  Here, the discounts are just on the food portion of the bill so if they have no food, a discount might not be possible.

They can discount the T-shirts and other gear in the gift shop then.
Edit - if they have a gift shop.  But the real reason to open a brewery is to clean things and sell T-shirts.  ;)

- develop a capping system that takes into account the history of a brewer's performance in NHC - start at a cap of 3 entries for brewers who have never made it past round 1; bump up to 6 if brewer has made it past round 1 but not placed; unlimited if you have placed (or some variant). Probably would require some type of database system to manage that could possibly be subsidized by higher fees and requiring AHA membership. Or cap entries for non-members first, then graduate it up for members based on their history.

Well that would be good for me, but how about the current "homebrewer of the week" Dave Motter if rule this was in place last year?  He did pretty well for a first time entrant.

This from the last question in the series.

I entered my first NHC in 2011 and was humbled with 2 medals and was part of a 3 way tie for Ninkasi (losing due to first round points).
 
I submitted beers into 10 categories and advanced 4 to the final round, taking Gold with my American Amber Ale and Silver with my English Mild Ale.  I made it to the semi-finals in the Samuel Adams longshot competition with my Dopplebock.  It was pretty cool getting feedback from Jim Koch, although a free trip to GABF and having it brewed by SA would have been better.

If there is a forum meet up this year, I will try and not wander off right before hand.   :P

Every thing that you mentioned would be good to have. Turkey fryer, chiller, and pump would be good.  Do you have outside hose bibs at the condo? You will be outside with a turkey fryer, and you could hook up to those and run the spent water into the grass or plants once it cools off.

Chillers are easy to make, consider that to save a $ or 2.

Good luck and don't be too disappointed if you don't do very well or the feedback looks it was written by a hallucinating junkie as most judges seem to leave feedback like that. Hope your beers will be judged by the rare lucid ones.
Cheers!

Have you ever judged a flight  category 19, Strong Ales in the morning?  That will do that to you!

Using Gordon Strongs 3 entries to 1 medal ratio, if you want to be confident that one of your beers will get a medal, 9 entries is not a lot i.e. 3 advance and 1 places in the 2nd round.

Things have changed a lot since I went to my first NHC in 2003.  I have entered the last 3 and the competition is getting pretty tough.

The conference location will be an issue in the future, it will need to be in a bigger convention city with good sized hotels that can handle a bunch of people.  I remember when the NCAA final 4 was plangyed in 20,000 seat arenas, or smaller.  It used to be at Kemper arena in KC often when the NCAA was headquartered in KC.  Not anymore, it is in larger cities with a stadium large enough to seat a huge crowd, adn the hotels that can handle that.  Not saying it will be that big, but the needs of a larger conference will force changes to where it can be.

I saw the H1 to H3 and the T1 at the museum in Greenwich some time back.  Have they been moved?
No, they haven't moved.  The clock collection at the British Museum covers clock history but there are some nice examples fo the evolution of navigation clocks.

OK, got it now.  The H1-3 are very large and intricate.  The T1 looks like a 6 inch diameter pocket watch.

They also have some other timepieces on display at Greenwich, including the current atomic clock that keeps Greenwich Mean Time (or at least a display of the time to about 8 places to the right of the second place - most were a blur).

Beer Travel / Re: Mainz, Germany Brew PUbs or Beer Halls?
« on: March 05, 2012, 09:35:17 AM »
There is a Brewpub in Mainz.  Forget the name, sort of SE of the Altstadt at the base of a hill.  Food was good, but all the beers had a mild house flavor, that was a little lactic.

I would use the harvest date and then the temp and packaging type used in in storage, at least that is what I have done in Promash.

Ziplocs are not O2 barrier bags BTW.  The foodsaver vacuum packing material is said to be O2 barrier.

Saw Gordon at a the WEB competition judging this past weekend.  Someone asked if he had entries in the NHC, and he smilled and shook his head no.  At least that is what I remember.

The burner I have is simmilar as to the actual burner, but a different stand.  I use a converted keg, and really don't have issues, but I don't go full bore either. Don't know of I would melt AL with the flame sttings I use.
