Default Austin Homebrew Rogue Imperial IPA clone not an Imperial IPA?

I was going to brew a batch of this IIPA this weekend but as it turns out it's not an Imperial IPA. It's even a little light in the SRM department to be considered an American IPA.



15 lbs of American 2-Row (the site says 16 but they only gave me 15)
1 oz Newport 60 min
1 oz Cascade 30 min
1 oz Sterling 15 min
1 oz Amarillo Dryhop

According to Beertools.com:
OG: 1.070
FG: 1.013
SRM: 5.14
IBU: 53.4
ABV: 7.5

Anybody else notice this?

Something looks off. I just checked out the site. Like you stated, the site says the kit comes with 16 lbs of grain. By the looks of the mini mash, you should have around a pound of another grain. Maybe some crystal or munich. I can't imagine an IIPA with just 2-row.

As to your calculations, do you have it set for 5 gal? I just plugged 15 lbs of 2 row into Beersmith and got an estimated OG of 1.082.

AHS has excellent customer service. I'd PM or email Forrest and see if there was a mishap.

When I run those numbers, I get about 1.078 (my efficiency is set at 70% but I usually get a bit higher) and 64.5 IBUs. Definitely in the IIPA range to me.

I guessed at the AAUs of the Newport hops at 14%- I know they are usually pretty high. If yours are lower, the IBUs would be lower, of course.

Yeah, maybe if you're doing a 5.25 gallon batch and your efficiency is 70%. Mine is a little higher. If your efficiency is 70%, you may want to make a 5 gallon batch if getting the OG up some is important to you.

Most beers are made entirely from 2-row barley.

The type in IIPA happens to be an English pale ale malt. I assume AHS is using a domestic type.

The hops are wrong, and not enough.

Yea...I know what beer is made of. Read what I wrote. I just haven't seen too many IPA's or IIPA's made of ENTIRELY 2 row.

FWIW, DFH 90 min is 100% 2-row.

Looks ok, though I'd ask them to send you the extra pound of malt.

Clone recipes are hit and miss - there are too many process and system-specific variables to guarantee that a homebrewed recipe will taste like the commercial version. I prefer to start from a good base recipe and then tweak it over several brews until I achieve what I set out to.
