Madame is quite the appropriate moniker, as Madame Rose is more than just another one of the sour sisters - she is the mother of them all. This is by no means an insult to the other four sisters, but more a compliment to Madame Rose.
The dark brown red color, tang of the wine barrel aged cherries, and wild yeast combine to create a spectacular sour ale. Madame Rose has a strong sour taste, in the vein of Belgian Krieks.
Personally, I prefer my sours to be sour, and Madame Rose does that perfectly without losing the complexity of the cherry flavor. If Goose Island continues to brew masterpiece sours, I may admit to preferring the sour lineup over the stout variety. Which is saying something.
Madame Rose weighs in at 7.1% ABV, and is available in San Francisco now in 765ml bottles.
