If you want to remove alcohol from mead, the best way is to boil off the alcohol. Since alcohol has a low vapor pressure, you can use that to your advantage. Pour the mead into a pot and heat it to around 175 degrees F (79.4 degrees C). Maintain that temperature and let the mead continue to boil for 15 to 20 minutes. The alcohol will be released into the air. Afterwards, cool the mead before drinking. The downside to this process is that you lose some of the characteristic flavors of authentic mead.
