Mort Subite Gueuze
I had this with a mussels dinner at a restaurant in Couvin Belgium. It was poured into a Mort Subite chalice (every beer I tried in Belgium was served in the correct brewery's glass). It looked pretty nice, copper color with a really long lasting sticky white head. It smelled and tasted slightly sour, but not as severe as a Flanders red. In fact I heard the sour flavor is subdued in this beer by the addition of some sugar after fermentation. I'm not sure if this is true, but there was some sweetness in the flavor. I bought another bottle to take home, as well as a bottle of Mort Subite Oude Gueuze (which doesn't have the late sugar addition). I'll see if I can taste the difference.
