This is one of the additional quests you can do during Yule Festival if you have a Brewery building in your settlement.
Note: The objective map markers in this quest are currently (December 18, 2020) a bit buggy so don't trust them.
The brewery is a mess and Tekla has vanished. Investigate what happened.
Talk to the guy named Alwin that can be found inside the brewery. He will tell you that you should find Ake.
To find Ake you need to leave the settlement and head east to Grantebridgescire.
You will find Ake standing on top of a cliff.
Talk to Ake, he will not initially want to do what you tell him to do, so it will be necessary to pour some sense into his head.
Beat him in a fistfight.
Head to a nearby bandit camp which can be seen from the cliff - Utbech.
The barrel is located inside a round hut.
You'll need to carry the barrel to Ake's boat. You should head west away from Utbech until you reach a road, then follow the road south to the river. Put the barrel down next to the boat.
This will end this quest, you will receive 140 tokens and "Ake The Brewmaster" is now an available opponent in the "Yule Brawl" quest.
