General Homebrew Discussion / Black IPA recipe formulation question/problems
« on: September 06, 2012, 10:56:04 AM »
Hey all,
I have a question about recipe formulation. I am currently in the process of creating a Black IPA (CDA, whatever, you know what I mean). I usually use a combination of calculations by hand from Daniels’ “Designing Great Beers” book and the BrewPal App on my iPhone because I am OCD. But this time I am having some decent discrepancies and would like your opinion before I go any further…

I use 10.5 gallons for my calculations for final batch size (usually try to run off 12 gallons of wort from the Mash/Sparge, assume about 1.0 boil off over 60ish minutes and lose about .5 elsewhere)

68% assumed brew house efficiency

Target OG; 1.060 Target IBUs: 60 (ish)

My planned recipe is-

2 row pale malt (80% of grist): 20.5 lbs
Crystal 40L (10%): 2.7 lbs
Chocolate malt (5%): 1.7lbs
Midnight Wheat (5%): 1.2 lbs

Columbus hops (14.6%) 4 oz @15 from flameout
Nugget (12.2%) 2 oz @ 15 from flameout
Columbus 2 oz & Nugget 2oz @ flameout
Columbus 2oz & Nugget 2oz @ Dryhop, 7 days

The problem is with my IBU/GU ratio. I would like it to be less than 1.0, but above 0.9 …
The BrewPal program has my OG (for the above listed grain bill) at 1.064 and the IBUs to be 63 for a ratio of 0.98 which I am happy with. But, when I do the calculations I use OG of 1.060 and get 85 IBUs for a ratio of 1.4, which I is a little more than I am looking for…

So, does anyone have any suggestions or thoughts about which one is right and if it’s even significant? I’m not worried about the slight difference in OG but the IBUs seems pretty far apart. Thanks!

Equipment and Software / mash tun upgrade
« on: November 03, 2010, 06:46:03 PM »
I was wondering if anyone had advice as to the best way to upgrade my system, specifically my mash tun...Currently I brew 10 gallon batches with a 20 gallon brew kettle, and two 10 gallon modified rubbermaid coolers as HLT and Mash Tun. The mash tun maxes out around 30lbs of grain and a 1qt H20: lb grain ratio. My question is; Should I buy a false bottom for my 20 gallon boil kettle (turning it into a mash tun) and buy a Blichmann 15 gallon brew kettle, or just buy a generic 15 gallon kettle/false bottom combo? It seems like they are pretty close in cost when you consider the Blichmann has all upgrades standard. Any thoughts? Also is there anything I'm not thinking of, I know that now I will need to apply heat to the Mash Tun during the mash to maintain temp since it's not insulated like the cooler. Thanks in advance.

Beer Travel / Beer in France
« on: June 21, 2010, 12:02:22 PM »
Hey Everyone,
 I'm going to France (Paris then the south Toulon/Nice area) and was wondering if anyone has any recommendations for places/styles of beer to try or good tours, anything BEER...etc...Yes I know France is "for wine". Also, I am planning on going to Au General La Fayette while in Paris (as listed in All About Beer's 150 places to drink a beer). I'd appreciate any tips,
        thanks,
      Adam
