Give your beer or wine the taste of fine Oloroso Sherry with these oak chips. These are made from real used sherry barrels and have a slightly sweet, nutty aroma. They provide a smooth sherry flavor that is perfect for sweet sherries, many sour beers, and other styles. Recommended use is about 10-60 grams per 5 gallons, with a contact time from a few days to a few months. One 250 gram pack should contain enough chips for five or more 5 gallon batches.
