In the time I spent in Holland in 2000 I didn't really get to enjoy any craft beer from Holland and at that time I am not really sure there was much of a craft beer scene in the country. We mostly drank Belgian beers and the main Holland beers like Amstel and Heineken.
Flash forward to 2008 and it looks like the craft beer scene in Holland is alive and well although maybe not known to the world outside of the Benelux (or outside of the "ne" in Benelux). I discovered a few of these Holland beers when we visited my favorite bar in Utrecht, Kafe Belgie. I also found a bunch of them at a great bottleshop we found in Utrecht, Bert's Bierhuis.
We also found a good beer scene in Amsterdam, one that I had not really explored in the past. We searched out and found 2 good beer bars and 2 good bottles shops.
