Update…. There was 1 bottle that had firmed up and carbonated. I thought it would be an infection and maybe it was but…. I chilled it for a couple of days and it’s…. Delicious! I need to save this batch!
So, 2 weeks ago I put a sprinkle of CBC-1 yeast in each bottle and made sure they were kept at 19 to 20c. There was a little bit of vegemite smell but this has dropped right away and been replaced by cocoa and roast flavours.
Still no carbonation.
When I originally bottled them I added 1 coopers carb drop per 740ml bottle. This is usually perfect for stout. I assumed that as there had been no previous carbonation the sugar would still be there and the CBC-1 would kick off.
should I try again with some more CBC-1 and add a new carb drop?
The single carbed bottle was so good I don’t want to send the rest down the drain!
Any advice would be great fully received. Thank you.
My advice would be to give it more time…like a couple of months. I had issues with the first few imperial stouts I brewed. One batch I gave up on and dumped. The second one, I was frustrated and nearly gave up, but decided to hide it away and try to forget about it. It had little to no carbonation and no head at all. A few months later, I chilled one and it was fantastic. Carbonated with a nice head to it.
I have brewed this recipe a few times since, but I gave up on trying to ferment it with S-04. I enjoyed the flavor, but getting that stuff to attenuate is a challenge and adding some CBC-1 was a must. I tried US-05 and Nottingham, but really wasn’t too happy with the character of the beer. I think I added CBC-1 to those as well, I can’t recall.
I finally decided to try Imperial Darkness. It finished within a couple of points of where I expected. I only bulk aged it for a month, and decided to forego the CBC-1 and let it do its thing. I was not disappointed. It was actually carbed after a few weeks, but still needed to age. After about 6 months or so, it was just amazing.
I have a few bottles from that batch left, and I also have brewed a couple batches since (both 2.5 gallon batches…one kegged and one bottled). The kegged batch is long gone, but I still have a few from the bottled batch. So, I have a few bottles from about a year and a half ago and a few bottles from February of this year. The older batch has kind of lost it’s character, though it is still a good beer. The one from February is still going strong…in fact, I took what was left to a family get together just last night. Everyone who tried it loved it.
So in closing, Imperial Darkness rocks, and aging this for a minimum of three months after packaging is crucial IMO.
