It's not enough for brothers Pat and Dan Conway to make award-winning beers; now they want to save the planet too. They've implemented a wide-ranging system of "Zero Waste Initiatives." That's their fancy way of saying they do smart stuff like using the brewery's spent grains to grow shiitake mushrooms and as feed for organically grown beef. They also recycle nearly all of their cardboard, glass, and paper. Also, they fuel the pub's free, biodiesel shuttle bus (affectionately called the "Fatty Wagon") on used cooking oil. They even employ earthworms to produce natural fertilizers for the herbs used in the pub's kitchen. But nearest and dearest to the hearts (and palates) of real food fans, they've made their entire eatery smoke-free. If that doesn't merit a toast, we'll eat our biodegradable hat.
