Recipe adjustment of my session IPA

[stijn26]

Hi,


I currently use this recipe to create my session ipa of 4,3% abv (4% abv before bottling).

Grain:
100% pale malt, mash at 66° celsius for 35 mins

boil for 75 mins:
Chinook 44 gr at 15 mins
Chinook 133 gr at 55 mins
Mandarina Bavaria 133 gr at 55 mins
Chinook 88 gr at 70 mins
Mandarina Bavaria 300 gr at 70 mins

Dryhop for 6 days after primary with 350 gr chinook.


I now want to lower the abv to 4,1% (3,8% before bottling).
At the same time, I want to increase the body and mouthfeel but don't want the flavor of the malt change too much.

As for the hops, they were okay in this recipe. However I want to put the focus more on aroma and flavor. At the same time it should have a nice bitterness to it.

I have come up with this recipe:

Volumes & Gravities
(Note that VAW below is the Volume at Flame-Out (VFO) less shrinkage.)
The, "Clear Brewing Terminology," thread at http://www.biabrewer.info/

Total Water Needed (TWN): 53,84 L = 14,22 G
Volume into Boil (VIB): 50,13 L = 13,24 G @ 1,032
Volume of Ambient Wort (VAW): 38,5 L = 10,17 G @ 1,04
Volume into Fermentor (VIF): 33,5 L = 8,85 G @ 1,04
Volume into Packaging (VIP): 31,02 L = 8,19 G @ 1,011 assuming apparent attenuation of 73 %

The Grain Bill (Also includes extracts, sugars and adjuncts)

Note: If extracts, sugars or adjuncts are not followed by an exclamation mark, go to www.biabrewer.info (needs link)

55,1% Pale Ale (6,5 EBC = 3,3 SRM) 3233 grams = 7,13 pounds
10% Tarwe / wheat (5,5 EBC = 2,8 SRM) 585 grams = 1,29 pounds
5% Flaked oats 295 grams = 0,65 pounds!
30% Maris Otter (6 EBC = 3 SRM) 1759 grams = 3,88 pounds


The Hop Bill (Based on Tinseth Formula)

9,2 IBU Chinook Pellets (11,2%AA) 10,9 grams = 0,385 ounces at 75 mins
15,3 IBU Chinook Pellets (11,2%AA) 38,2 grams = 1,346 ounces at 15 mins
4,4 IBU Mandarina Bavaria Pellets (7,5%AA) 16,4 grams = 0,577 ounces at 15 mins
4,4 IBU Chinook Pellets (11,2%AA) 27,3 grams = 0,961 ounces at 5 mins
7,1 IBU Mandarina Bavaria Pellets (7,5%AA) 65,4 grams = 2,307 ounces at 5 mins
0 IBU Chinook Pellets (11,2%AA) 32,7 grams = 1,154 ounces at 0 mins flameout
0 IBU Mandarina Bavaria Pellets (7,5%AA) 98,1 grams = 3,461 ounces at 0 mins flameout
0 IBU ??? Pellets (11,2%AA) 182,6 grams = 6,441 ounces at mins (Dry Hopped)

Mash Steps

Mash Type: Pure BIAB (Full-Volume Mash): Saccharifiaction for 35 mins at 69 C = 156,2 F

Strike Water Needed (SWN): 54,91 L = 14,51 G 69,6 C = 157,2 F

Hello!

The flavor of this beer will change quite a bit. You are adding three different types of malt, as well as raising the mash temperature significantly. This beer will have a lot more body and be much sweeter than the original. If you're just after increased body, I'd suggest using up to 5% Carapils / Dextrine Malt and keep the mash temperature the same (66C).

As for more hop flavor and aroma, the best result would be to take the 2 additions you're adding at flameout, and instead add them in a whirlpool for 15 minutes after the wort has cooled below 175F. This will prevent a good deal of isomerization and retain much more aroma and flavor.

Hi,


Indeed, after some reading and another topic I already took the decision to just add 5% CaraPils. However I probably will mash a little higher, see what it gives.
I will change the flameout hops to the whirlpool instead. Thanks!

I will post the result in this topic.

Upping the Maris and lowing the Pale with give more mouth and sweet maltiness too

You can go larger on the oats also

That hop bill looks complicated

Why does it look complicated [emoji3]
