Mr. Beer 740ml Deluxe Beer Bottling System

Mr. Beer’s Deluxe Bottling System includes 12, 25 oz. reusable, shatterproof bottles. These bottles allow brewers to perform a “squeeze test” to ensure the beer is fully carbonated, so the beer stays completely sealed until it is ready to drink. If bottles are opened before carbonation is complete, unwanted oxygen is introduced to your beer, which can cause off flavors and aromas.
