Stash tea company is a privately-held company headquartered in Oregon, a suburb of Portland. They sell only the finest specialty tea with 100% natural ingredients, and happen to be one of the largest tea companies in the United States!
The company derives it's name from an entertaining aspect of tea folklore. In early centuries tea was a valuable commodity traditionally transported by clipper ship. The ship's captain often was presented with some of the finest teas for his personal use. This supply was his "stash", stowed carefully as his "private reserve". Today the term is still used to denote anything put away carefully because of its preciousness.
