Well, I brewed this up again for this year. My goals were: to thicken it up. To get maple this time. Less oak.
I also wanted to bump this up a little higher than 9%... I got way more than I bargained for, as I tried a new method for brewing this.
===============================================
---Fermentables---
14.0lb 2-row
2.5lb Oats
1lb Oven Toasted Oats
1lb Coffee Malt
1lb Chocolate Malt
0.5lb Carafa III dehusked
0.5lb Roasted Barley
1.0lb Maple Syrup @7-14 days after pitching
---HOPS---
@60min: 1 oz Cluster
@30min: 1 oz Willamette
@5min: 1 oz Willamette
---MISC---
@5min: 4oz Cocoa Powder
@7days: 4 oz Cacao Nibs & 2 Vanilla beans (I'll boil both in ~150ml water for better extraction, cooled and tossed in)
@3-4 days before bottling: 4oz Whole Bean coffee (bourbon barrel peruvian)
Mash at 154 for 60min
150 min boil
So biggest changes, I bumped the grain bill up to 20.5lbs. I went with about a 1.3qt/lb ratio of (diluted) water which I treated with Gypsum, CaCl and Baking Soda.
I have a friend who advised me on doing a double mash, no sparging and a long boil.. So that's what I tried. I basically bought 40lbs of grain and did the entire mashing process twice and only drained out the water I put in. With the calculations I did, I was going to get about 4 gallons out each time, and that is exactly what I got. I started the boil with 8 gallons, boiled for 2.5 hours and I ended up with around 5, which I was hoping for 5.5ish, but that is fine.
The initial calculations had my dialing in a 1.116 OG... It WAY exceeded that. I ended up with a 1.138 OG which blew my mind. I figure I got about a 90% efficiency with this process which is crazy. I think 70% was the most I had previously had on my system with any other beer, granted, this was an entirely different process than I'd tried before. The strange thing was I had read other people using this method and getting far less efficiency. Either way, I would have liked a lower OG, but I'm not too upset at this point.. I'll wait to see how it turns out.
When I pitched, I had put in a starter that began with 1L, that I decanted and stepped up to 2L a day or two later, crashed overnight, and decanted the next day before stirring up a couple hours before pitching.
Last year I added the maple syrup around high kruesen and I never got any noticeable maple-I still don't, and I just had a bottle that's been aged a year now. So I want to add this a little later this time to ensure it doesn't ferment out. I might be pushing my luck though, as I'm just worried about bottle bombs the addition of priming sugar when I bottle a couple weeks later... Anyone have thoughts on that?
@7 days (1 week after pitching), I'm going to try boiling the nibs and beans in 150ml water and adding that this time. Last year I did a tincture that I added them to 2-4oz bourbon 5 days before I added them into the beer. The flavor was fine, I just want to try a different method to see how it works for me. Depending on where the gravity is at at that time, I may or may not add the syrup. Haven't made a decision on that yet.
@14 days, add a tincture of 4oz bourbon that I have had soaking in 1oz oak for the last month or so. Last year I did 7/8oz in 2oz of oak.. I got too much oak. The bourbon was pretty smoky on it's own which I guess I didn't really realize. I also pitched the entire thing in last year.. This year I will just do the bourbon only. I might add another couple ounces of just bourbon too. I didn't get any taste of bourbon last year. I don't know if I will this year either just with how high the alcohol climbs haha.
@4 days before bottling I will add the coffee beans. Had good luck with that last year, and I love coffee flavor. I'm excited to try these beans I found as well, hope they taste as good as the name implies.
So as for the fermentation process, it's been 2 days. I never got a high kruesen and I don't remember if I did last year either. It was highly active for 24-36 hours, but it's dialed back today. I haven't taken a reading, but I do hope the gravity has dropped. I only created a starter with enough yeast cells to account for the 1.116 OG, so I'm worried I underpitched. I used Wyeast Irish ale yeast as the company I bought from was out of WLP004, which I was a little disappointed about-I've always had good luck with it. They sent me a 004 that was packaged in January of this year, and past it's expiry date.. I pitched that along with my starter because I would have thrown it away otherwise. Figured it couldn't hurt.
So let's say this weekend I check and fermentation has slowed and the gravity is still up there.. What are my options? I've never had a stuck fermentation. It's in a 65* environment, but the temp on the glass is in the 70s with active fermentation going on. Do I make another starter and add it? Just throw a straight package of yeast in? Yeast energizer? Looking for a backup plan ahead of time in case that's the situation I am in.
Anyway, hope this info helps anyone who's been watching this thread and looking for answers. I'm excited about this beer, even if it does reach a peak 15-16% haha... It will definitely be a celebratory beer to keep for awhile if so.
