“What material is used for the carafe, and how does the cork stopper with a silicone seal help preserve the freshness of the coffee concentrate?”

1-1 of 1 Answer

• The carafe of the OXO Brew Compact Cold Brew Coffee Maker is made of borosilicate glass. The cork stopper with a silicone seal helps preserve the freshness of the coffee concentrate by creating an airtight seal that prevents oxygen from entering the carafe. This prevents the coffee from oxidizing and losing its flavor.
