Rocka Rolla Woman for a Rocka Rolla Man

Here's another Magic Hat beer that was a pleasant surprise. The Roxy Rolles smells so good, I thought that maybe I mis-judged amber ales altogether. While that might be a little out of hand, this is really a good beer.

In fact, it is so good, that I thought I would like to clone this and keep some around. The ingredients from the Magic Hat page are simple: Pale malt, Caramunich, and crystal malt. With an ABV of 5.1% and the gravity of 14.5 Plato (1.059 SG), I determined that the FG would be 1.022. Is that right? I would think you could get the FG down to at least 1.016, if not 1.012. Maybe my ABV calculator spreadsheet is incorrect. If anyone has a simple method of determining ABV from OG and FG, that would be helpful. I'm using two equations to get there.

It would appear from this fellow beer blogger, that they have changed the recipe, though. Looking at the hop profile, which is 20 IBU, the same as the Jinx, I was kind of confused. They use CTZ hops in the jinx, and Brewer's Gold and Simcoe for the hop profile on the Roxy Rolles. It only takes about 0.75 oz BG hops and 0.25 oz of Simcoe (at 15 minutes) to go over 20 IBU. Then I remembered how hoppy the aroma was and thought maybe they dry-hopped the beer with Simcoe. The above article confirms this. Also, I can make more sense with the older recipe's IBUs.

Rocka Rolla Ale (a Magic Hat Roxy Rolles clone - sorta)
5 gallon boil

8.0 lbs Pale Malt
2.0 lbs Crystal Malt 90*L
1.0 lbs Caramunich

1.00 oz Brewer's Gold @ 60 min.
0.25 oz Simcoe @ 15 min.
0.50 oz Simcoe dry hop in secondary

California Ale V Yeast

O Gravity: 1.058
IBU: 35
SRM: 23

I went with the California Ale V yeast because I like the American style yeast more for hoppy beers. I will check how my Jinx clone turns out, though, and if I like the London Ale yeast, I will go with that. Oh, and the name of the beer is a play on the original as well as the title of a Judas Priest song and album.
