Saviah Cellars in Walla Walla, Washington using portable Pulsair TM-1501W mixer for mixing grape cap skins and juice during fermentation in 1-2 ton macrobin fermentation tanks. This air mixing process or 'reverse punch-down' process may be used exclusively or along with traditional punch-down to quickly and safely manage caps during primary fermentation. The wine quality is enhanced by uniformly and gently mixing the cap, reducing the reduction by releasing non-fruit aromatic esters and completely breaking up the cap into individual berries allowing all the juice to come into contact with yeast bodies.
