Help Converting Brewery (Pipeworks) Recipe

[bmwwd6]

I recently reached out to Pipeworks Brewing out of Chicago asking about their recipe for Blood of The Unicorn (Imperial Red Ale). They responded with the following:

60% 2 Row
17% Munich
7% C80
6% Special Roast/Special B
4% Rye
2% Flaked Oats
.5% Midnight Wheat
3.5 % Dextrose

Hopped to ~60 Ibus (following are amounts for a full 7bbl batch and are in pounds)
2.5 Chinook @ 60

1 Chinook @10
1 Zythos @ 10
3 Falconer's Flight @ 10

5 Falconer's Flight @ 0
5 Zythos @ 0
2 Chinook @ 0

Dry hop on day 7 with a combo of those three at a total of around 12 lbs per 7 bbl

Mash at 150 for 1 hr

8.5% ABV

We use safale US-05

I have only been brewing for a year and am inexperienced when it comes to scaling recipes down and converting them. I was hoping a more experienced member could help me out. I figure it would be easiest to scale it down to a 5 gallon all grain batch and then convert it to extract. I'm not sure if this matters, but I boil the most wort volume my pot will allow which is usually 4 gallons and utilize late extract additions. I appreciate the help, and I just wanted to share the recipe with the community. It's a great, complex beer with a ratebeer score of 98!

I've never done this before. So if anyone notices some errors, please let me know. I used the given grain percentages and 72% efficiency to get the ABV to 8.5%. I used the 60 IBUs and relative amounts of hops to get the hops additions.

Commercial breweries (at least all the ones I know of) do a whirlpool and a rest afterwards at the end of their boil so those 0 minute additions would contribute to the ibu of the beer.

The amount of utilization is debatable. For example, the brewery I work at does 15 minute whirlpool and a 15 minute rest before knocking out into the fermenter. We calculate our 0 minute addition as a 20 minute (the wort is still hot enough to isomerize the alpha acids but we don't see as much extraction as we would for a 30 minute addition. I speculate this is on account that the wort in the whirpool isn't as turbulent (applying as much energy to the hops) as it it would be if it were boiling).

It would be helpful to learn how long their whirlpool times and rest are as well as what formula they use to calculate their ibus (assuming the 60 ibu they give you is calculated and not tested).

Also special roast and special b are completely different malts...not sure why they would give you the recipe like that.

Hope this helps!

I'm just trying to get as close to the real thing that is practical. If beersmith says its ~60 ibus that should be close enough. Did satph's beer smith scaling look correct to you skibb? If everyone agrees it looks as accurate as practical, could someone help me convert it to extract?

When I get home I can double check and run the numbers through beer smith for ya

Thanks appreciate it! I'm concerned the specialty grains in this recipe need to be mashed and won't work well being steeped? If this is the case let me know and I'll save this brew for when I go all-grain.

I emailed them back asking about the Special Roast vs Special B. He made a typo, they use Special Roast. I sent him the rest of the recipe and he said it looked good. He also added that the Midnight Wheat goes in at the end right before the vorlauf begins.
