Having spent several hours online researching Chaga, I'm very glad Birch Boys finally popped up. The difference in apparent quality between BB chaga and other brands was striking. The 16oz bottle came with a pump and funny little measuring device. Two full pumps dispenses just slightly over their 'serving size' of 4ml. Taste? It's like a very mild Root Beer or Sarsaparilla without the added sugar, and perhaps a little smokiness reminiscent of maple sap as it comes from the tree (when making syrup). Quite palatable. Mixes immediately in a small glass of water with no stirring necessary, just a few swishes. Shipping across the country was fast. With its very eco-conscious harvesting approach, excellent website and fair pricing I am glad to recommend these guys to anyone. A classic American small-business success story, I reckon...
