Is that decaf or not
If you have ever gone into to Starbucks or one of the other coffee stores and insisted on a decaf, but without seeing the person making the coffee personally, so what do you do. You have two choices grin and bear it or insist on checking them making the coffee.
However, fortunately there is something coming to the rescue for you doubters, Silver Lake Research have come up with these decaf beverage test strips. Put this is coffee and it will tell you decaf or not decaf, unless you have a latte, syrups of sugar in your drink.
