Their web page is tastyflavors dot biz, they are concentrated drops, no sweeteners added. The only ingredients say "Toffee Flavor, FDA Approved".
It's 1.5 oz for about 4 bucks. You put 4-8 drops in your drink, and says that one bottle will do 160-180 servings. I've been putting about 5 drops or so in and it might still be a bit much.
They have their flavors on the web page, but most of them seem to be fewer than the ones that divinci has, but I can only get suger free divinci vanilla and hazelnut at my grocery stores, vs most flavors of these. I found them in the coffee section of the grocery store. (Sorry, I hate buying things online, so I always try to find them here first)
I only bought one bottle to test, but I think I'll go back and get the southern pecan one and maybe a white chocolate one next.
