Is this the most efficient Double IPA ever brewed?
“When we knock it out to the whirlpool, that’s when we add Incognito®. Very easy to add product. Liquid hop extracts that readily want to get out of the container. We’re really happy with it. We were able to get an additional 2 HL, compared to the beer without Incognito®, which was huge. So not only are we sitting with two additional hectoliters of wort in the whirlpool, but instead of 15 kg of hop matter in the bottom of our admittedly undersized whirlpool, there was just 5 kg of hops and some Incognito® that is now in the beer.
So it’s gonna be easier for us to get that into the fermenter and not incur losses there. We got more into the whirlpool and I know we got more out of the whirlpool. Generally when you do hoppy beers, our hop cone likes to collapse, and cover the lower valves, from which we can collect wort. We were able to go all the way to the bottom and collect dry, that usually doesn’t happen. That was big!”
“Based on our previous experience with using Spectrum, we have decided to add it early this time. If brew day is day zero, then we added Spectrum two days after the brew day and then the pellets went in right after, which is the next day, so day 3. We didn’t add Spectrum as early as we wanted to, but also not as late as last time. After that, we added our BBC and T90 pellets. So for our Double Apocalypse (reference beer), we had a total of 20 g/l dry up, which is 80 kg that go into 40 HL fermenter. We decided to go for a 50/50 split, so we kept 40 kg of T90/BBC pellets in the dry hop and then went for 5 kg of Spectrum. That was a very different approach than what we have been doing so far. Most of our past approaches were Spectrum heavy, but this time it was way more balanced. Also, this Spectrum was one of the easiest Spectrums to add to the fermenter. We purged it, added our Spectrum and had some de-aerated water that we then mixed in to get out any remaining extract that had clung to the sides of the vessel, which we then put into the hop gun and later to the fermenter. We repeated the same process with our traditional T90 and BBC pellets.
We dried hop warm so we let the fermentation finish out and any hop creep finish out. Then we cooled it down. We did our standard conditioning time, only because we couldn’t squeeze it any faster, even though we probably could have turned the spear over faster. In the end, we got more beer in cans than what we are all so used to having. On the last Double Apocalypse (reference beer), we got 31 HL and on this one we got 35.8 HL unpackaged beer, which is a big difference. Admittedly, the yield on our Double Apocalypse was a bit lower than it should have been – it is usually 32 Hl of beer. But, we are comparing those two beers, because everything is the same - the same bulk silo delivery, and the specialty malts are from the same pellets. If we are going to compare like for like, that was the difference. But in any case, we have never brewed a Double IPA with more than 35 yields out of 40.
Those are the numbers; and numbers don’t lie!“
Feedback from Amundsen's internal team
"The feedback that we got from the team has been that this is a highly drinkable Double IPA, it drinks pretty well for a beer this size - which is a big compliment. It is a nice internal win for us to have the team to be on board with 8,5% Double IPA, instead of 4% ones. As brewers, we don’t add a lot of hops to the whirlpool as our brewer’s gut or heart tells us to because we would lose a lot of yields, which becomes exponential on the big beers. For the big beers we struggle to even get a post-boiled dilution. If you’re going to go heavy on the whirlpool edition, you might as well just say goodbye to that. Not that everything is about yields, but it hurts to go through the steps of brewing a beer and allocating a whole fermenter knowing that we are only going to get a fraction of what we could have from the whirlpool, then have it sit in the cellar for a couple weeks, only for the packaging to tell us that there’s not enough beer to go around for everybody. We try to get as much as we can out of every brew and Incognito® definitely helps with that a lot. Not only does it help to get out more, it allows us to add the amount of hops that we really want to use in the first place. We would love to use the whirlpool hops at around 5 – 7 g/l range, but usually only use around 3,5 g/l."
