Yeast and Fermentation / Re: Next improvement Oxygenation
« on: February 16, 2014, 05:17:30 PM »
IMO if you are repitching yeast or making big beers you definitely want to make sure they have sufficient o2 whether from o2 tank, shaking, etc.  If you are making normal strength beers (1.056ish) and not reptiching  dont worry about it much

Definitely go with sanke, you will be fighting an uphill battle to get places to take cornys.  Also if you have a good pump you can CIP a sanke easily and not have to pull the spears every time.

Cornys really suck, 5 o rings vs 1 on sanke and many more places for a possible leak.  Sanke couplers have built in check valves as well

Wow 25 candidates

Yikes, hopefully this process smooths out

It's much smoother than last year.  Within an hour of registration opening there were tons of complaint posts in the forums so I'd like to give a big thumbs up to the staff and process so far.

I think getting the actual number of entrants/entry count is awesome.  Data is king and the fact that they ran the numbers a bunch of ways is truly awesome.  Props to Janis and the aha staff making this happen.

Definitely good luck in cat 14, I gave up entering that one when I got a 47 in first round but didn't pass the minibos, same beer won many other awards around the same time.  This was when it was only single bottle for first round so it should be better now.

The 1st person I heard from who got their results had entries in Seattle, but he was also a volunteer last year.  I picked Sacramento as my first choice with Seattle as one of the alternates and got into Sacramento (also judged 1st and 2nd round last year).

My email was caught into the Promotions folder on gmail, so make sure you check there if you use gmail.  From address is if you are searching your spam folder with subject of "Action required: Registration Confirmation"

Maybe this year we can arrange a more formal AHA Forum meetup at NHC and put faces to names.

Just like the past two years, my forum name will be on my badge

The registration and payment went off without a hitch for me.  The only issue I am noticing is where I choose where I want to judge.  I don't want to judge in Chicago (where my entries are going) I want to judge in Zainsville... How can I register to do that?  The form only lists the Chicago judging sessions.  Thanks.

I recall reading something about this before.  After the entry deadline is closed I believe you will be able to sign up on your chosen site as a judge/steward.  I'm in the same boat as you, entering Sacramento but will judge in Seattle

The article says that the 7% will be given a shot at abandoned registrations
Can't find the article Jim, point me to it.

Thanks, thought it would be on the main page. Well, now we know the demand as far as number of brewers.

Edit - clubs e-mail list is asking if anyone has been notified. None so far. Anyone?

I know 1 person so far that has received email, I also know other people from same region who did not receive it yet.    Based on my small data set I'll speculate that people with last names starting with A received their email and every hour another letter should go out.

Kegging and Bottling / Re: Carbonation and perceived bitterness
« on: February 10, 2014, 11:44:59 AM »
Yeast definitely are bitter.

I've never noticed yeast being bitter by themselves, but I'd aay that in bitter beers the yeast are absorbing some iso-aa or they are sticking to the outside of the yeast cells

General Homebrew Discussion / Re: Hop Utilization
« on: February 10, 2014, 09:07:48 AM »

The way I understand it, the amount of hops pulled from a bale to analyze for acid is minimal. THAT sample on THAT day was X % acids. Saying that the little ounce or pound bag that we buy is X% is just a generalized idea.

There are varying calculations for determining the level of IBUs in the wort post boil. I don't know which one your software uses, mine has options. Tinseth or Rager, I use Tinseth in spite that he's an Orygonian.

I would guess that my actual hops are what the package says they are, give or take 10%. My projected target IBU in the wort is probably within 10% of what the computer says, plus the 10% variance from the hops. Minus who knows how much that is lost in fermentation due to off gassing and attaching to yeast and dropping out.

I can honestly say that I have no idea how many IBUs are in my finished beers. The only way to know would be to send it to the lab.

So, saying that our beer has X amount of IBUs is technically inaccurate if it's based only on an IBU calculator. But, if you use a calculator, change the drop box AA numbers to what your package says, measure accurately, add them at precise times, chill the same way each brew, etc... you will have a good baseline to work from to make adjustments in the future.

In the end, I don't sweat the small stuff. I call it what the calculator says. Works for me.

Just to add to it, they only spot check something like 1 bale in 5 or 10.

For all grain on my half barrel system, Tinseth is pretty good for beers less than somewhere around 70 IBU calculated. All of the calculators overestimate at higher IBU levels. I know, some of my beers were tested. When you see some brewery advertise 200+ IBU, you can say it was a calculation, not measured.

You're right on the number of bales they check on both bit my memory escapes me which is which.  One of the tests is the USDA stems and seeds check and the other is for lab analysis. 

Bales should be reasonably uniform though, the hops get moved around enough they get mixed up pretty well during all the steps from picking to baling.

Also pellet hops should have a more accurate AA% on them because 5-15 bales are blended to produce the pellets.  They also can go and retest them after thr fact easily.

I had a couple like those, I pulled them and drilled the hole a bit bigger and used a normal as one instead

I've done that, it really wasn't too difficult to do. I took pictures years back when I did it but I'm not sure where they are.  Since I used a digital a/c unit I figured out what resistance the temp probe returned at a high and low temp and matched resistors to those and use a relay to switch between the resistors.  So when I want the ac running I make it think the temp is 85 and when I want it off it thinks it is 65.

I have mine hooked to a manifold I built with PVC and solenoids for each of my brewhemoth fermenters.
