I'm starting a long-running series of single-hop IPAs. I will be making them in 2.5 gal batches by splitting a 6 gal mash into two boils then ferment side by side. Making two at a time should help me pick out differences in process vs differences in the hops (i.e. batch A and B had X flavor, but C and D are so and so...)
This will be the called "69 IPAs" series and I'm shooting for 1.069 OG, 69IBU and 6.9 SRM. Whether or not I make it to 69 batches over the years will depend on the doctor's orders
For hops, the current candidates are:
- Hallertau Mittelfruh
- Nugget
- Northern Brewer
- Saaz
- Amarillo
- Simcoe
- Citra
- Colombus
- Cascade
* Willamette
* Summit
* Chinook
- some NZ varieties - any thoughts?
* Galaxy
* Nelson Sauvin
* Riwaka
- some British varieties - any thoughts???
* East Kent Goldings
* Styrian Goldings
- any others??????
* Centennial
* Calypso
* El Dorado
* Sterling
* Glacier
* Athanum
Will aim for this water profile found in another thread: Ca-110ppm, Mg-118ppm, Na-17ppm, SO4-350ppm, Cl-50ppm.
Here is the base recipe, adjusted for 5 gal batch size (sorry about the funky qties, I'm working in metric and just set it to imperial to post here)
Amt Name Type # %/IBU
12 lbs 5.5 oz - Pale Malt (2 Row) US (2.0 SRM) Grain 1 90.0 %
1 lbs 5.9 oz - Carared (20.0 SRM) Grain 2 10.0 %
0.62 oz Nugget [11.10 %] - First Wort 60.0 min Hop 3 23.5 IBUs
0.62 oz Nugget [11.10 %] - Boil 40.0 min Hop 4 18.7 IBUs
0.71 oz Nugget [11.10 %] - Boil 15.0 min Hop 5 12.1 IBUs
0.71 oz Nugget [13.00 %] - Boil 10.0 min Hop 6 10.4 IBUs
0.71 oz Nugget [11.10 %] - Boil 5.0 min Hop 7 4.9 IBUs
0.71 oz Nugget [11.10 %] - Boil 0.0 min Hop 8 0.0 IBUs
0.71 oz Nugget [11.10 %] - Dry Hop 0.0 Days Hop 9 0.0 IBUs
One of the tougher issues is how to brew this with the lower alpha varieties. I will most likely do most of the adjustment in the FW and 40m additions, while only slightly increasing the 15, 10, 5, 0, and DH hops, since scaling those proportionally would require a massive amount of hops and make it hard to compare aromatics of the different varieties.
Using Carared for the first two batches but may go to C20 for future ones. Any opinions on Marris Otter in an IPA? (Would probably use it by itself at that point to avoid overpowering the hops, with maybe a pinch of black for color).
Yeast will be US-05 to start. Once I identify some favorite hops and experiment a bit with blending (a vertical tasting would be cool, but not practical given the time it'll take to make all these), I'll ferment a combined recipe with 3-4 different yeasts to find the "mother of all 69 IPAs"
Any thoughts on malt bill, hop varieties and schedule, or anything at all really, are welcome!
Cheers
