The recipe says 60 min boil, but has anyone tried or recommend taking the boil a bit longer to 75 mins or maybe even 120 mins? I've heard with bigger beers like barleywines and imperial stouts people prefer to do longer boils cause its supposed to develop more complex caramelization, and more of a rich character.
Heidi Gray on Jul 2, 2020
BEST ANSWER: Depending on the initial wort volume and boiling setup, I will often boil longer to bring down the final volume. I typically determine how long (75 / 90 minutes) before I start so I can stay to within the recommended hops time. Not sure how much it adds to the 'complex caramelization', but I always enjoy the end results!
Any suggestions on mash time, 60 minutes? 90 minutes?
Rick Hausauer on Aug 3, 2018
BEST ANSWER: Hello Rick,
I did a 60 minute mash. However I normally do a pretty slow spare which has helped my starting gravity quite a bit. Also, you may consider adding air to your wort just prior to pitching your yeast. This has helped my attenuation greatly. Good luck and have fun.
I brewed this on Aug 12th and it's still fermenting as of right now (Nov 21). Is this normal? I used the cellerscience British yeast.
Juan B on Nov 21, 2023
BEST ANSWER: Three months is a pretty extended time for a beer to ferment. Even a big imperial stout. I normally do not rely on the airlock to tell me if fermentation is complete. I usually look to see if the kreusen has fallen. The thick foamy layer on top of the beer will thin out and you can usually see the part or all of the surface of the beer with foam absent. If I really Want to confirm I will take a sample and measure the gravity with my hydrometer. I’d like to see an Imperial Stout finish with a gravity under 1.030.

Better than expected
I was a little worried when I was going to make this beer as I'm still fairly new to all grain brewing. I don't think I put enough water in for the mash (I've figured out the right calculations now) but somehow it still came out great. I might order this one again and actually let it age in the bottle, they went fast.

Won 3rd place in my brewer's league SRM 30+ competition
I brewed this with my favorite fresh ground coffee. It turned out excellent. In fact is has become my all time favorite. It won 3rd place in a competition with 17 entries. I will definitely be brewing more of this. A lot more.

Amazing Stout
I have brew this beer many times. I love the heavy Imperial Stout. I have several times infused other flavors into this beer. The last time I juiced up pomegranate and added it to a secondary ferment to experiment.

Awesome Stout
Brewed this up a month or so ago...it's conditioning in the keg now, plan is to not tap it until this winter... we'll see how long that lasts. The beer tasted phenomenal when it was transferred to the keg...I've brewed a lot of Morebeer's all grain kits and they always come out awesome !!!

Great Beer
I've bought this recipe 3 times now. It's a great beer to build on. I've done barrel aged with 2 of them and I'm now doing a Mexican Hot Chocolate.

Delicious robust flavor, gets better with age!
This is a really nice beer! Best to let it age for a few months (goes without saying, I know). Try putting it on oak chunks that have been soaked in bourbon for an extra treat!
