In archetypal fashion you and your heroes are sitting around a table in a bar. You are discussing the possible adventure before you. Do you need to take on the Forge of the Dark Machine? You must. How do you prepare yourselves? You ponder over a draught of Dwarven Ale. It’s strong, stout, and resolute: much like the Dwarves that brewed it. You can taste the rich flavors as you dwell on the dungeon delve and feel the foam of the head hit your lips and gauntlet. You could swear this transcended the game.
It did: you had the beer in-game and out-of-game.
Beer is a staple in fantasy; you meet your group at a bar, or there is probably going to be a situation in which you will have a pint with your fellow party members. Why not bring it to the table along with your character sheets? Sure, you could grab any old bottle of whatever and chug it. I personally would prefer the real thing. Think about it. Eladrin Ever-Mead. The Eye-PA of Grummsh. A Pali Pale Ale. Garl’s Gittery-Glug. Brew-hamut the Platinum Flagon?
