Hoppin' Frog's D.O.R.I.S. the Destroyer is a Double Oatmeal Russian Imperial Stout, and it is stealth and seductive. It pours oily black with no real head, just a little brown foam that vanishes in a hurry. The aroma is hearty malt, espresso and coffee. The mouthfeel is a little thin, but not horribly so. The flavor has all of the aroma's notes and a little hop twang, but no real heat to betray that 10+ percent ABV. I didn't realize how substantial it was, or how quickly I'd blasted through this bomber until I stood up to go down the hall to the bathroom. Be careful with Doris, she'll have her way with ya.
