Each flavoring is packed in a 4 oz bottle. The recommended usage for beer is on the label and listed below. For wine we recommend adding to taste. Fruit Flavorings are best added as late in the process as possible to help preserve as much fruit flavor as possible. If using for wine, add to ''bottle ready'' wine one week or so before planned bottling, stir gently and let the wine sit for 7 days before actually bottling.
