Coopers DIY Beer 740ml Oxygen Barrier Home Brewing Beer Bottling Set, Qty. 15, Brown

Coopers DIY Beer Deluxe Bottling System includes 15, 25 oz. oxygen barrier, 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.
