I wound up emailing him. I wasn't looking to clone it exactly, I was really just looking to get some of the overall citrus character. Anyway, here's what I wrote:
Hi,
I've been really impressed with the citrus character in the St. Bretta beers I've tried. I love the zesty, slightly tannic character. I want to brew a little sessionable Saison, and I'd really like a push in the right direction to get that character.
Looking over the photos on your sight I saw that you zest and juice the citrus. I also saw pics of rinds in the kettle.
I'm thinking of zesting and juicing about 1/2 pound of oranges/tangerines (5 gallon batch at 1.040), and adding the whole mess in (juice, zest, rinds and all), during the hop stand along with a half oz of Galaxy and a half oz of Goldings. Letting that steep at 160* for 10min before cooling and pitching.
Does this sound like a good approach? I'm wondering about the juice, if maybe I should leave it out? And if 2 pounds is a bit heavy handed.
Thanks for any help you can give,
Jack
And what he wrote back:
Hey Jack,
1/2 pound sounds good to me for what you're looking to accomplish.
We use the zest and juice but stay away from the rind as it adds astringency and bitterness. Zest very finely!
Cheers,
Chad
I also found that Hill Farmstead's Brother Soigne had a similar citrus character, so I sent him an email:
Hi,
I recently got to try a bottle of Brother Soigne, and I have to say, I thought it was one of the tastiest beers I'd every had! I loved the long-lasting citrus character and vaguely tannic quality.
I'm planning to brew a low gravity, citrusy Saison. I spent a long time browsing the web seeing if Shaun Hill gave away any of his secrets/brewing techniques. No suck luck. But I did see on a Reddit interview that you'll give advice on recipes. So, here's what I'm planning, can you give me a shove in any direction? I'm most curious about how to deal with the citrus.
Anticipated OG 1.040
5 gallon batch
75% Pilsner Malt
10% Rye Malt
10% White Wheat Malt
5% Acid Malt
90 min boil
15 IBU bittering addition at 60min
5 IBU Styrian Goldings at 10
Cool to 160*, add 2 pounds oranges/tangerines (zested and juiced, adding all parts) plus .5 oz galaxy and .5 oz Styrian Goldings
Steep 10 min,
Cool to 70*
Pitch saison and brett.
Any help would be hugely appriciated!
Thank you,
Jack
He said this:
Looks like a great recipe to me!
Just make sure you have plenty of healthy and viable yeast cells and that you oxygenate well!
Send us a bottle =)
But searching around the internet I found an article or two where Shaun discusses ICU's (international citrus units), his own way of measuring the citrus character in beers. There wasn't much info, but for the one or two beers he listed the ICU's, you could figure back how much zest (by weight) he adds (but not when). Using his calculation, my batch had about 5 times (if memory serves) how much citrus zest he uses for beers with a strong citrus character, (tho I'm guessing he adds the zest at knockout, not 160* like I did.)
Anyway, the recipe I posted is coming out well, but like I said, it's not exactly a clone. The citrus is in the right range. However, if I were to do it over I might use a little less at knockout so that I could have more predictable results. Also, the brett character in this batch is really shining, I'm not sure if that's the result of the Acid Malt or the Saison strain in the blend (WLP670).
Hope some of that helps!
