Ambassador Barrel Aged Sour Ale

Not much information available as it is a very limited release beer:
10 I.B.U.s
One review on Beer Advocate:
Ordered this one at __________ not really knowing what it was. Thought it might be a sour…
…and it is. Pours a murky, faded golden yellow. Minimal head that fell to a slight collar.
Aroma is tart fruit, some wood and faint spice. Lemon and orange zest, with some green grass.
Flavors are nice. The fruity sourness balance is pretty darn good. Kind of sweet up front, then the tartness starts to pucker, and a quick gut punch of sour comes in. What I like about this sour, and I’m not a sour beer guy, is its finish. Dry with a hint of sweet ‘n’ tart to leave the palate cleanly. Good carbonation lifts the residue. Ready for another sip. May be a touch heavy for a summer day.
