Going Pro / Determining Wastewater Info
« on: December 25, 2012, 07:01:08 PM »
Hi all,
Getting ready to open up a 3BBL brewery in southern CO and have been trying to get more information on determining estimated BOD, TSS, TDS, etc. counts. The waste water manager is new to the position in our town and is looking for me to provide all the information on what we expect to be sending down the drain since he is unfamiliar with the brewing process. I have been asking around with all the brewers I know and no other brewery I have talked to has ever had to present this information to their waste water plant manager. Does any one have a source or matrix on determining estimated BOD and TSS counts? Ultimately I think that with the small brewery we are opening we will not be sending a lot down the drain compared to the big breweries out there, so basically I just need to educate the guy. But first I need to educate myself...

General Homebrew Discussion / BJCP Certified Stout Competition Announced
« on: November 30, 2012, 03:37:53 AM »
I just received a notification from our local brewery about a Stout Only competition if anyone is interested in participating. They are confirmed with Dave Houseman for BCJP certification. Rules below:

Pagosa Brewing & Grill
Stout-Only Homebrew Competition
for Stout Month 2013
(Sorry, professionally experienced brewers excluded)

In conjunction with our upcoming Stout & Chops Month in February 2013, we are challenging Stout Lovers to create a homebrewed Stout to help us celebrate.

In 2012, we offered 16 different Stouts (8 in-house & 8 guest). The winning homebrewer will have the opportunity to join us and brew a full sized 6bbl batch of their Stout recipe, which will be featured for Stout Month 2013.  The winning brewer will also receive a $50 gift card & bragging rights.

1)   Entries must be Stouts (no Porters, Black IPAs, Black Lagers, etc.)
2)   Entry must be under 8% ABV.
3)   This is an AHA sanctioned competition & BJCP style guidelines will be used for judging:
4)   Creativity of ingredients is encouraged, but not required.
5)   All entries must be delivered by Friday, 1/4/13 to Pagosa Brewing.
6)   For each entry, three 12 oz. bottles are required.
7)   Entries need to be labeled with names, styles & any necessary info.
8)   Participants cannot have professional brewing experience.
9)   Brewers cannot use our house yeast.
10)   All winning recipes will be considered Pagosa Brewing recipes, and at our discretion may (or may not) be brewed by us in the future.

For questions, please email:

Good Luck & Happy Brewing!

All Grain Brewing / Post Boil Gravity Question
« on: November 01, 2012, 01:56:38 AM »
Hi all,
Long time member, first time post-er...

I have been experiencing an issue that has me stumped. I use BeerSmith to formulate most recipes and it auto populates many fields. The one number I can never nail is the post boil gravity / OG. I can mash in and nail my pre-boil gravity (sometimes getting better efficiency than expected), but at the end of a 60 minute boil my gravity is much different than the program estimates - like we are not concentrating the wort as much as the program expects, but still getting the yield expected. For example, on an IPA we recently brewed, the estimated pre-boil gravity was supposed to be 12.45 Plato (1.050). We actually measured 14 Plato (1.057), so we achieved great mash efficiency and everything seemed to be on track, even above expected (hey, I'll take a bigger beer - why not?). So we at this point had a higher gravity wort than the program estimated. However, after a 60 minute boil, the program estimated our original gravity should be 15.15 Plato (1.062) and our measured OG was only 15 Plato (1.061). The batch size in the program and the measured batch size matched. So if I started off with a higher gravity than expected and then boiled down to the same batch size the program expected, you would think that my OG would be higher than the program expected since my pre-boil gravity was higher than the program expected. The program thought I should go from 12.45P to 15.15P (an increase of 2.7P) but I went from 14P to 15P (an increase of only 1P). This has happened several times and I am trying to nail down what is causing it. Some factors to consider:

1) We are brewing in Colorado at 7000 ft, so atmospheric pressure is different than you would see at sea level. We leave a lid partially on to try to get some head pressure.
2) We try to maintain a steady, rolling boil. It can vary since we are brewing outside, but we recognize a vigorous boil is preferred. (Maybe because we are insane hop heads we are not boiling vigorously enough because we fear losing hops in a boil over?)
3) We start the boil with 12.5 gallons and the program estimates we will end up with 11 gallons (10 gallon yield, one gallon lost) which we do.
4) Ultimately I think I have something off in BeerSmith because things just don't add up.
5) Next brew I am going to use a different hydrometer. I have heard the standard homebrew hydrometers can jack things up. Maybe a pro-grade will help? I hope that is it, but not so sure.

Any other thoughts out there?

Thanks / Cheers,
