General Homebrew Discussion / June BJCP Exam Results
« on: November 19, 2015, 06:47:30 AM »
Today I opened an e-mail with the results from an tasting exam I sat for after the NHC. It seemed to have gone well, even though 2 weeks in CA and the NHC put some pressure on the study time. My goal was to score at least 80.

The good news was that I scored 85. That made me very satisfied, my first tasting score on the legacy exam was 67. So I learned between exams, and the allergies were not acting up.

Now I need to retake the written, which will be the 2015 guidelines. That is the bad news, as there will be much study required for this old guy.

The Pub / Constellation Brands Buys Ballast Point

The $1Billion price blows the $1k*bbl/year benchmark out of the water. Which brewery is next?

Yeast and Fermentation / Wild Yeast from the UP of Michigan.
« on: November 12, 2015, 07:25:41 AM »
This was an article that had a few things that hit on a few personal levels. I have had a beer fermented with one of the wild yeasts, and it was pretty nice. The reference to Eagle River meeting Lake Superior made me smile, as there is a small inn with a fantastic bar there, one of our favorite places - The Eagle River Inn and Fitzgeralds, known as "the Fitz".

I got 4/5. Missed the Geo. Washington question.

General Homebrew Discussion / The Hop You Hate
« on: October 15, 2015, 09:32:18 AM »
In another thread Denny talks of his dislike of Fuggles. I know Gary Glass shares that opinion.

I can't stand Nelson Sauvin, I get cheap foxy white wine out of it.

Mrs. R absolutely hates Simcoe, she will make a face and say "Cat Pee".

We all have different tastes, we are not alike.

What the hop you dislike and never ever will brew with?

The Pub / Bell's First Beer Fermented in the Cypress Vats From Stroh's
« on: October 06, 2015, 12:53:51 PM »
I will be at the AHA Rally on Sunday at Bells and will have a pint of this. Might even write a review.

Ale made with Chevallier malt, fermented in the 100 year old cypress fermenters that were originally used at Stroh Brewing.

The beer.

The malt.

Events / YCHHOPS Hop and Brew School Review.
« on: September 05, 2015, 09:15:04 AM »
We went to Hop And Brew School put on by YCHHOPS,

This was 2 days and cost $200 per person. Was it worth it? Absolutely,  it exceeded expectations, and I will attempt to explain.

Once you are checked into your hotel, transportation out and back to the event is provided. At the event you are provided 3 meals a day. There were also tubs of commercial beer and a kegerator if you are thirsty. Many were thirsty.

The morning sessions were presentations by the likes of YCH personnel, Patrick Smith (Loftus Ranches), Stan Hieronymus, Gary Glass, Denny Conn, and Ann George (USA Hops). These were all very good.

The afternoon sessions were field trips. The first day was to see the pelletizer operation in Sunnyside WA, and then the extraction facility and warehouses just down the street. The supercritical CO2 extraction facility look like rocket science, and it did use high temperature and pressure to extract the lupulin resins. Simcoe is being harvested now, and trucks were delivering bales in the warehouse area, the smell was wonderful. A brewer's cut was made in front of us, and we got to grab some Simcoe out of the bale.

The second day was a tour of Perrault farms facility, which is new. They had to expand the processing plant as more acres have been added to their operation. We saw trucks being unloaded and the bines placed into the picker, and then saw how the cones were separated from the bine and leaf material. We then went to the kilns, saw the bottom plenum, then went up the stairs where it was hot and humid and our glasses fogged up.

Then it was off to the experimental field with Jason Perault, who explained the breeding program and toured us through the rows of single plants, then an area with 7 plants of each experimental variety. We got to pick and rub cones from random experimental plants, including 291, and 438 (Ron Mexico).

The last part was sensory, where we smelled small sample jars of aroma compounds. Then it was samples of hops and asigning values to aroma descriptors.

To sum it all up, I came away with a much deeper knowledge of hop farming and how hops are processed and distributed. The experience was high in the fun department too, and well run. Mrs. R and I came away with the impression that the YCH personnel and the Perrault family truly enjoyed hosting the event.

I rate this just under the NHC as far as a fun and educational beer experience. We will go back some year.

Can't make NHC some year, go to Hop School.

Have questions about hops and hop farming, go to Hop School.

Your wife asks what you want to do for your birthday, and it coincides, go to Hop School!  8)

Beer Travel / Boulder CO and Sedona AZ
« on: August 24, 2015, 11:40:34 AM »
A road trip to meet several other couples has been planned for October.

Never been to Boulder, so we are staying 2 nights, and know we should go to Avery, Upslope. We are staying in an AirB&B near the Pearl St Mall, so Mountain Sun will be a stop too. Any others? Non beer related recommendations are welcome too.

Sedona, well I have driven trough there many times starting back in 1984, last time was 10+ years back, and I know it will have changed. We have 4 nights there. Any recommendations? Will probably go to some of the Natioinal Parks and Monuments to make use of the new Senior Pass I have, got to get my money's worth.  8)

Flagstaff will be a stop for lunch one day. I know it has changed. More breweries today.

Sad, but Fred was full of life, and was a pleasure to have a conversation with.

The Pub / "The Martian"
« on: July 27, 2015, 05:03:06 PM »
Searched for this and did not find a reference to "The Martian" by Andy Wier. Finished it last week, very good story of an astronaut stranded on Mars. Pretty good on the technical parts. Story is involved, and full of points in the plot where the Martian environment almost kills him. A good read.

It is being made into a movie, Matt Damon as the lead, Ridley Scott directs.

Ingredients / Downey Mildew and Michigan Hops

I am seeing some on my hops. It has been really wet here. This is one of the reasons hop growing left the Midwest for the PNW. In recent years hop growing has started to come back to MI, approaching 500 acres this year.

There was a discussion on how to transfer beer and minimize staling in the beer here.

Sean makes the statement that if you have a DO meter you become shocked as to how much purging is necessary to achieve low levels. How much is that?

There are procedures to purge vessels of toxic or explosive gases. If you search for "pressure cycle purge equation" you will get hits to some links with information. Without going into all the details and the derivation, you can estimate how many purge cycles you need to reach a level of gas concentration.


N=Number of purge cycles
Clow=Lower concentration target
Coriginal=Original concentration, so for air that is 0.21
Plow=Low pressure, 14.7 PSI absolute for our application
Phigh=High pressure for the purging, I use 30 PSI gauge, so 44.7 PSI absolute

For our case.

selecting a sequence of 0.1, 0.01, 0.001... we can calculate the number of cycles. Round up for your application.

Concentration   #purge cycles.

0.1   0.6671342451
0.01   2.7375696785
0.001   4.8080051119
0.0001   6.8784405452
0.00001   8.9488759786
0.000001   11.019311412
0.0000001   13.0897468454
0.00000001   15.1601822787
0.000000001   17.2306177121

So to get close to 1 ppm (0.000001) you need 11 purge cycles. State of the art canning and bottling lines have about 50 ppb TPO or less.

That will use a boatload of CO2 for an empty keg, so the technique of pushing sanitizer out saves on CO2. If the head space is purged 5 times at 30 PSI, then the headspace will have about 1000 ppm O2. The headspace is small, so there is not a lot of waste for that process.

I hope this helps.
