Roastaroma is an herbal tea made with roasted barley and chickory, plus a few other flavors.  They changed the formula 5-10 years ago; I have gotten used to the new one, but I was disappointed at the time.  If you like coffee, but you cannot have ANY caffeine, you need this product.  Keep some in your bag and the glove compartment:  you can have a decent hot drink anywhere there is hot water.  It's strong enough for a pint or more of tea. I buy mine by the 6-pack from Amazon.
