Interesting. Other marketing moves such as the Guinness Toast and Guinness Extra Cold (do I have the name correct?) must not have effectively maintained their sales.
A pint of Guinness has long been one of my favorites. At my old spot in western Massachusetts I put down so much of the stuff I would probably have to estimate total volume in kegs rather than pints. I don't know if Brew 39 will be available in the Seattle area but I'll give it a try if I see it. If you try it, as I'm sure you will, let us know how it is.
