Okay, took a chance...
Uncorked the glass carboy, and poured a splash into a 12 oz. brandy snifter...
Color: rich, clear amber
Legs: medium to medium thick
Nose: so heavy on raisins anything else is lost
Taste: huge raisin to start, slap upside the head of black cherry at the end
Finish: silky and warm.
Went back, and gave myself a healthy pour.
Thoughts: This is a tawny port deprived of cask-aging. From the way I'm feeling, I'm going to guess at an ABV of 20%-25%. This stuff is strong!
