Expansion on Perceived Bitterness

card2

In order to better illustrate the perceived bitterness relationships, I have written a short javascript calculator that does the math.  This way, you can adjust the ratios between Original Gravity, Final Gravity, and IBUs to see how they affect the BU:GU ratio, Apparent Attenuation, and Perceived Bitterness as described by The Mad Alchemist.

I hope you find this calculator helpful.  Have fun brewing!

In the below calculator, we’ll use the estimated IBUs, Original Gravity, and Final Gravity to calculate perceived bitterness using Ray Daniels’ BU:GU Ratio from Designing Great Beers and then using the formula created by The Mad Alchemist, which also factors in Apparent Attenuation.

Brewing Session Beers

At the August 2014 meeting, I presented a brief educational discussion on brewing “Session” beers.  Below is an edited version of the presentation, including the portion in which I described using math to compare the perception of bitterness between two beers.  If you have any questions,please feel free to comment below.

Meeting Themes and Mother’s Day

mday-art

Hello, Zymurgists!

We’re quickly approaching the Mother’s Day Festival and we still need folks to volunteer to man the booth with Randy.  He’s volunteered to set up, but we have very few people volunteering to sit and drink beer and talk brewing with interested people.

This is one of our highest-profile events of the year, so let’s try and make a good showing of it.  If you plan on being at Mother’s Day, please contact Randy or comment below and plan on spending some time in the booth. Even if you’re not sure when you’ll be available, letting Randy know he’ll have some hands to help talk brew with people will help a ton.

If you’ll direct your attention to the left of this post, you’ll see I have posted the meeting themes for the rest of the year.  This should help you plan ahead to brew for meetings or just prepare for a meeting.  In addition, if you find you’d like to teach a breakout session, contact Mr. Becker through the forums.

Thanks for helping to promote craft beer in Southwest Missouri!

We need volunteers!

We have two events coming up quickly, and we need some homebrewers to join us in promoting our hobby!

On May 3rd, Todd and the crew at The Homebrewery in Ozark will be hosting an event in honor of the AHA’s Big Brew Day. If you are interested in being a participating brewer, please email todd [at] homebrewery [dot] com and let him know. This event is coming up very quickly, so please email him soon if you are interested in brewing.

On May 17th, Mother’s Brewing Company will be hosting their 4th Ever Mother’s Day Festival in their backyard. ZOO Members who will be at the event should contact me or Randy West and let us know. Randy is organizing our effort at the event, but you can also email me at homebrewzoo@gmail.com if you are interested and I will relay your information to Randy.

The event runs from 2-8pm, but we specifically need volunteers for set-up and tear-down.

For both events, please wear your ZOO gear if you have it. Let everyone know we’re out there.

Thanks,

Ben

Big Brew Day is May 3rd!

If you are planning to brew for Big Brew Day on May 3rd at the Homebrewery, please email Todd Frye (todd@homebrewery.com) and let him know which recipe you’ll be brewing and how much of that recipe you’ll be cooking up.

For information about the recipes, see the American Homebrewers’ Association Website here:

Have fun brewing!

April 2014 Meeting Minutes

4-15-14

@ The Home Brewery

11 in attendance

7:50 Open

In order to expedite meetings the old business/treasury report/most updates will be done online, unless there are specific interests in certain subjects.

Also we are asking that home brew be labeled with at least brewers name and style of brew. This can be anything as simple as masking tape and sharpie.

8:05 Mother’s Day @ Mother’s is coming up as well as Big Brew Day. If you have interest in either contact one of the officers.

8:07 Keeping up with the website. This is a tricky one, as we all have lives (somewhat) outside of the club. Ben is working with Keith W. to help bring it up to speed.

8:10 Saison themed education portion and tastings with Chris B.

8:25 Close for social period.

7:58 Treasury Report

7:59 Competition Update:

“Art of Darkness” should be completely closed out, all awards given, and all information handed out.

Spring Competition: styles have been selected and posted. Working on ideas for the name, also dates (possibly March 15th or 22nd)

8:00 Beerfest:

Working out who will be present and bringing brews with. (After: the event was a success with great ideas on years to come. Generated lots of “buzz” <–Pun intended, and even made the paper with Keith B.’s Cider. Here is Ashton and Bruce displaying their badges http://imgur.com/cIVLduW )

8:05 Barrel project update:

Barrel was filled, but still needs 15 gallons of liquid for top up. If you are interested please contact Chris Becker.

8:11 Honorary Members:

Aside from the guys at SBC we also thought it would be nice to do the same for a few of the people at Mother’s. Also we thought it would be good to present them with the ZOO t-shirt.

8:13 Growing pains and the Educational portion:

We have decided to keep the themes of each meeting, ie. beers to bring for that month ( not mandatory). But, move the educational portions to a different section. So those interested will be less distracted from others that may not be. Also, only having 1/4 of the years meetings containing an educational portion. This will allow them to be more in depth and personable. More to come.

8:16 Amendment to the Constitution:

Passed by well over a 2/3rds vote http://imgur.com/wN6bIYK

8:23 Brief discussion about the newsletter and a Recipe of the Month. More to come on that topic.
