The Siphon Spray Wort Aerator (BE510) is an affordable piece that helps introduce oxygen to cooled wort prior to pitching yeast for fermentation. Simply attach it to the end of your tubing and transfer to the fermenter as you normally would. The piece will spray the wort into the vessel, enabling improved aeration during the transfer process. Note: Designed for use with 3/8 I.D. tubing
