Let me start out by saying that don't have much experience with true lambics. I never know what to expect from these extremely wild beers they range from the sweet to the acerbically tart. I've never had an unblended lambic before. The closest I've tried is the gueze style(blended). Iris comes from the Brasserie Cantillon in Brussels. Pours a hazy honey orange with a moderate off-white head. The nose was sour with green apple and grapes and cheese. The taste is wildly tart and funky. Starting with an assertive sour mustiness then dry oak. The end is of citrus peel and sharp cheddar cheese. The finish is old and dry. Far too tart for my taste, however, it is complex and intriguing. This an interesting lambic to reflect over.
