The second fill for the Newfermenters Barrel Project Jack Daniel’s bourbon barrel is going to be a Robust Porter and will be filled in early November, 2021.

Key Dates For Filling

Friday, October 1, 2021
Payment of $15 per participant to be submitted to to secure a spot in the barrel.

The payment helps cover the cost of consumables used in filling, emptying, and maintaining the barrel. It takes a lot of CO2 to flush a barrel, push beer out of 11 kegs into the barrel, and push it back out into kegs at the end. Also things like StarSan, stainless steel nails, etc…

Tuesday, October 19, 2021
Approximately the last day to start fermenting and expect primary fermentation to be complete before the target filling date.  Past guidance suggests that bigger beers can take 17-18 days to fully ferment to final gravity.

Weekend of November 7/8, 2021
Target date for filling the barrel.  All beer should be finished fermenting primary and brought to Bill’s place in Torbay. Details for keg dropoff and barrel filling will be sent closer to the this date.

Key Dates For Emptying

TBD – Too far in the future yet.


This recipe is an adapted version of Port Rexton’s T-Rex Porter shared by Alicia in the Newfermenters Facebook group.

As described on the Nitty Gritty Details page, the recipe has been scaled to a brewhouse efficiency of 75% and it targets 6 US gallons post-boil to allow for some volume loss during transfers, some hydrometer samples to be pulled, etc… Feel free to scale to your own system as required.
