I brewed a 10 gallon batch of American IPA today! This is Batch #127.

The recipe's very similar to Sierra Nevada Torpedo Extra IPA that I've made before, with a few subtle substitutions like Warrior instead of Magnum as the 60 minute bittering hop and some Amarillo thrown in at 5 mins as I was a bit short on Magnum.

I thought I'd try something slightly more malty/biscuity so instead of 2-row and just Crystal 55L, I used Weyermann Pale Ale Malt and some Vienna and then dropped the amount of Crystal 55L. If you want something truer to style, replace both with 2-row at 95% and Crystal to 5%.

I also wanted something closer to 6-6.5% ABV instead of 7%+ so grain amounts were reduced accordingly. This is what I call a 'balanced' IPA with an OG:BU (original gravity to bittering units) ratio of 1:1.

Was targeting an OG of 1.060 and got 1.058 because I sparged a little too long (collected 14.25 gallons instea of 13.9). I could have boiled longer to compensate but I didn't bother. Other than that everything was bang on.

Ingredients:
18.0 lb Pale Ale Malt 3L (Buy at: Amazon, MoreBeer, HighGravity, AiH, NB, OBK)
3.0 lb Weyermann Vienna Malt (Buy at: Amazon, MoreBeer, HighGravity, AiH, NB, OBK)
0.7 lb Crystal Malt 50-60L (Buy at: Amazon, MoreBeer, HighGravity, AiH, NB, OBK)
2.0 oz Warrior Hops (15.4%) - added during boil, boiled 60 min (Buy at: Amazon, MoreBeer, HighGravity, AiH, NB, OBK)
1 Whirlfloc Tablet (Irish moss) - added during boil, boiled 15 min (Buy at: Amazon, MoreBeer, HighGravity, AiH, NB, OBK)
1.6 oz Magnum (14.4%) - added during boil, boiled 5 min (Buy at: Amazon, MoreBeer, HighGravity, AiH, NB, OBK)
1.0 oz Amarillo Hops (8.2%) - added during boil, boiled 5 min (Buy at: Amazon, MoreBeer, HighGravity, AiH, NB, OBK)
2.4 oz Crystal (3.3%) - added during boil, boiled 5 min (Buy at: Amazon, MoreBeer, HighGravity, AiH, NB, OBK)
24 g Fermentis Safale US-05 dry yeast (Buy at: Amazon, MoreBeer, HighGravity, AiH, NB, OBK)
1.2 oz Magnum (14.4%) - added dry to secondary fermenter (Buy at: Amazon, MoreBeer, HighGravity, AiH, NB, OBK)
1.6 oz Crystal (3.3%) - added dry to secondary fermenter (Buy at: Amazon, MoreBeer, HighGravity, AiH, NB, OBK)
2.0 oz Citra Hops (11.1%) - added dry to secondary fermenter (Buy at: Amazon, MoreBeer, HighGravity, AiH, NB, OBK)

Notes:
Add 500mg potassium metabisulphite to 20 gallons water to remove chlorine/chloramine (as required).
Water treated with brewing salts to: Ca=110, Mg=16, Na=16, Cl=50, S04=265
(Basically Randy Mosher's ideal Pale Ale numbers with slightly less Sulphate).
1.25 qt/lb mash thickness. Single infusion mash at 150F for 90 mins. Mashout to 168F.
60-90 min fly sparge with ~6 pH water. Collect 13.9 gallons in the boil kettle.
Boil for 60 minutes. Lid on at flameout with 0 minute hops, start chilling immediately.
Cool wort to 66F and aerate well. Ferment at 66-68F until complete. Dry hop for 7-10 days.
Rack to brite tank (secondary), crash chill to near freezing (if possible), add 1 tsp of unflavoured gelatine dissolved in a cup of hot distilled water per 5 gallons of beer, and let clear for 2-3 days.
Package as you would normally. I keg and carbonate on the low side (around 2 to 2.2 volumes of C02) to minimize carbonic bite and let the hop/malt flavour come through.

If you prefer to use liquid yeast, either of these is an excellent choice as they are the same clean fermenting Chico strain as US-05:

Wyeast 1056 American Ale (Buy at: Amazon, MoreBeer, HighGravity, AiH, NB, OBK)
White Labs WLP-001 California Ale (Buy at: Amazon, MoreBeer, HighGravity, AiH, NB, OBK)

You'll need to use 4 packs/vials or make an appropriate starter. For more information see Chapter 6 of How to Brew and Appendix A of Brewing Classic Styles.

Extra info:

Here's my water adjustments using EZ Water calculator found here: http://www.ezwatercalculator.com/
Goal: Target Mosher's ideal pale ale numbers- Enough sulfate to bring out the hops without overdoing it.

Randy's "ideal pale ale" numbers are:

Ca: 110
Mg: 18
Na: 17
Cl: 50
SO4: 350

(I use these for all APAs, IPAs, IIPAs, American Ambers, American Barley Wines)

Code:
Starting Water (ppm):               
Ca:   8.9            
Mg:   2.2            
Na:   16            
Cl:   6.1            
SO4:   27            
CaCO3:   32            
               
Starting Water (ppm):         
Ca:   8.9      
Mg:   2.2      
Na:   16      
Cl:   6.1      
SO4:   27      
CaCO3:   32      
         
Mash / Sparge Vol (gal):   7.3   /   9.2
RO or distilled %:   0%   /   0%
         
Total Grain (lb):   21.7      
Non-Roasted Spec. Grain:   3.7      
Roasted Grain:   0      
Beer Color (SRM):   8.6      
         
Adjustments (grams) Mash / Boil Kettle:         
CaSO4:   9   /   11.34246575
CaCl2:   2.5   /   3.150684932
MgSO4:   4   /   5.04109589
NaHCO3:   0   /   0
NaCl:   0   /   0
CaCO3:   0   /   0
Lactic Acid (ml):   0      
Sauermalz (oz):   0      
         
Mash Water / Total water (ppm):         
Ca:   108   /   108
Mg:   16   /   16
Na:   16   /   16
Cl:   50   /   50
SO4:   265   /   265
Cl to SO4 Ratio:   0.19   /   0.19
         
Alkalinity (CaCO3):   32      
RA:   -54      
Estimated pH:   5.37 (this spreadsheet for me is always about 0.2 too high, actual numbers measured closer to 5.2 which is bang on)


So I'm pretty close to his numbers. S04 is a bit low (265 instead of 350) but that's fine and is how I prefer it.
