There is a website called beeradvocate that has a directory and a "BeerFly Guide"

The BeerFly Guide is a part of the website where volunteers can maintain beerbaseed guides for various cities around the world. Dont miss bars and shops. It would be great to have a BourbonFly Guide section for SB.

I could voluteer for enter and keep updated the bourbon information for Japan.

The directory is just a list of all the breweries and bars of any value beer value. Which would be cool to have too.
