As soon as you walk in the door at the Taza factory in Somerville, you are hit with a chocolate aroma that will tell you you're in for a treat. Here, they craft stone ground chocolate unlike any you've tasted before. It's rustic, delicious, and so full of flavor, those other bars will be left in the rear view mirror.The owner discovered the chocolate on a trip to Oaxaca, Mexico, learned the technique and today is following the process of using granite millstones to grind the organic beans into flavors that range from coconut to chilpotle chili to their best selling salted almond. It's all dark chocolate-so it's good for you right? The beans are sustainably sourced and after a tour of the process, there will be no doubt that thinking about where your food comes from is definitely a good thing.
