I have been a loyal International Delight French Vanilla since it first hit the market, always buying the half gallon size. In the past month or so I've gotten 3 half gallon sized that are unusable...there is some kind of funk to the flavor, not sure if it's the container or what. My husband got the quart size and it's fine, but was told by a store clerk it now has the "funk." What has happened? I used this in more than my coffee...I used it instead of milk in my French toast and to make icing for cakes and brownies. As a loyal user I beg you to please change the recipe back!
