We do not fill growlers from other breweries for quality control reasons. We pre-fill all our growlers. First we clean, sanitize, and purge oxygen from the growler. Then we fill slowly from the bottom up to ensure the max fill. Then we purge the head space with CO2 to eliminate any oxygen that might remain. All of this is done to maintain the highest quality beer possible. When you fill from the tap, there is a lot of waste from foam and you don't get a maximum fill. If you return your empty growler and do not want another to replace it right away, we will gladly give you a wooden token that can be used for a future growler fee or receive $5 off of your total bill.
Contact us directly if you are looking to purchase more than 6 growlers at one time. We offer a reimbursement for glass fee if growlers are returned within two weeks of event.
