My bad, that's the other achievement.
You go get the quest to hunt ingredients. You collect these. You go back into the arena where the quest giver is located. Before handing the ingredients back in to the quest giver, you consume one of these beers. Then you hand in the ingredients.
Voila, achievement accomplished.
I am pretty sure you can just open your inventory and manually activate the "used napkin" to get this achievement. Worth a try anyway - find a player, open inventory, and use the napkin which is in the quest item section of your inventory.
