For aeration mortar, with 5 µm stone pore

Special aeration connector head with porous stone. Connect with 7mm PVC pipe for

use. The wort flowing through it will form tiny air bubbles through the pores of the stone.

Adequate oxygen saturation of the wort is a prerequisite for fermentation.

Cleaning: after use, immerse in boiling water.

Never touch the stone with your hands, as it will clog the fine pores!
