Beer: The unofficial beverage of fall; the elixir of tailgate parties; what we used to wean ourselves from Mama's milk during our first semester in college; the golden amber in our cups we sip while watching our alma mater play a homecoming game. We chug it. We sip it. We pour it in funnels. We then belch its wonderful aroma.
Sake: The warm clear stuff in a tiny cup that keeps our hands warm while we eat cold sushi. We sip it. We shoot it.
Now take that tiny cup and drop it into your beer. That's called a sake bomb.
What most likely started out as a chaser--also known in bartending parlance as a Boilermaker--is a beer/liquor combo: a shot of whiskey, vodka, or Tequila followed by a glass of beer. Then someone had the brilliant idea to just drop the shot of liquor into the beer. This new concoction was christened the Depth Charge, most likely in reference to something in a canister-like container that when dropped to the bottom of a body of water or other liquid has explosive qualities. One of the most famous Depth Charges is the Irish Car Bomb, which is a shot of Jameson Irish Whiskey in a pint of Guinness beer. Much like when you tap your beer bottle against your buddy's to make it foam up, when a shot glass hits the bottom of a glass of beer the same thing usually happens. The beer foams up and the owner of the glass must chug the whole thing to avoid spillage. OK, so it is not a cocktail for the refined. But in the case of sake bombs, there is an alternative, classier, way to imbibe this concoction.
The rules are simple. An empty sake cup is floated on the surface of a tall glass of beer. People take turns filling the sake boat cup with a dash of warm sake. The sake cup gets lower and lower in the glass of beer with each person's contribution. The person whose sake causes the cup to sink must drink the whole glass.
