Pulsair “Pneumatage” wine tank mixers, is an innovative and proven method for efficiently managing grape skin caps during red wine fermentation and wine blending. This extraordinary wine blending technique works by pulsing large bubbles of compressed air or gas near the bottom of the fermentation tank. The rising bubbles provide uniform temperature, keep yeasts healthy, and efficiently wet the cap to enhance the extraction of flavor, tannins and color into the juice. This process maintains freshness, reduces bacteria formation and helps expel unwanted wine mercaptans and volatile sulfur compounds. Unlike other methods, Pneumatage breaks up the cap into individual berries and circulates them in the juice, which keeps the cap in a semi-loose state making it easier and more efficient to regularly manage the cap.
