I've seen pretty much no press about this. There are seminars at the Park Plaza, but across the river at the Royal Sonesta Hotel is the Craft & Fine Spirit Showcase from 11-1 & 2-4. It costs $25 to get in. I went yesterday, and the place was empty. Since it is Saturday, there will probably be more people, but due to the lack of advertising, there probably won't be many people.
Too much good stuff to list, but some of the most interesting things that I've never had before were by Koval who had some interesting organic whiskys and cordials and Dunc's Mill who had an elderflower rum.
