Bottle from Taniguchi. Huge diacetyl nose, with lemon and banana. Estery, but butter is huge. Cloudy golden with a lacy head. Sour lemon and yogurt flavor, with diacetyl accompaniment. The tart, sour edge actually kind of works, though I am sure it was not planned. There is a very long-lasting astringent finish as well. The tangy quality is quite nice, like a Berliner. The nose and the finish are horrible. All kinds of things are wrong with this beer. Still not past drink by, so I think this was an issue at the brewery.
