From Main Street Brewing in Vancouver comes their “Cantus Fermus” a beer that uses the dregs from the bottle of a Cantillon.  The beer pours a orangy colour with an off white head.  The aroma consists of a nice funk, tartness, fruit and a good yeast backbone.  The flavour is of lemon, tangy citrus, funk, yeast, candies, sweetness with some similar Cantillon notes in the finish.    The alcohol content comes in at 5% with an IBU of 3.  The bottle was number 138 and bottled on October 0, 2015.  I think this bottle with do some good with some aging but the beer is quite interesting as it is!

Commercial Description:  Our award-winning Cantus Fermus is now available, while stocks last, in 750ml bottles on the retail side.
