FW recommends a 15% usage of this flavor. It is a very nice flavor but you will have to experiment and find the strength you prefer. Make up a 10% and a 15% and see what’s closest for your taste. You can then adjust if necessary. Good Luck…
They have two “crunch” cereals on their site, Crunch Cereal and Crunch Fruit Cereal so I’m guessing the Crunch Fruit Cereal is supposed to be like Captain Crunch Berries.
