Tasting Stale Porter: Soured Double Stout

Not what I had in mind when I blended a bit of sour beer into some stout nearly two years ago (Guinness FES is what I had in mind). I didn't consider what would happen when the lactic acid bacteria and super-attenuating Brettanomyces strains took hold in the lush, smoky stout.

All the roast, toast and smoke is still present. With it there is sharp, sour smelling funk. All present in the mouth along with solvent/plastic. The body torn to shreds. Thin, sharp and sour.

If you've had Madrugada Obscura from Jolly Pumpkin (who are usually great), this is like that. That austere sour character is not meant for stouts. Maybe I will try to mix a little bit into fresh porter to see if it gives a bit of complexity.
