Can’t believe I forgot to mention this most momentous of beer week events: the sour beer fest. Lambics, gueuzes, krieks? Heck yes. Brouwer’s is serving up over 40 sours including Verhege Duchesse de Bourgogne, a rich, Belgian red ale that is aged for 18 months in oak. (Brouwer’s shows its reverence for the duchess by hanging her portrait on the wall at the mezzanine level.) There are three from Lost Abbey, some New Belgiums and Russian Rivers, a bunch of Cascades. It’s a sour-lover’s ultimate event. Stop by.
