Since 1986, winemakers have been using Pulsair’s “pneumatage” efficient air mixing process during primary to mix red grape juice quickly and efficiently into contact with the bouyant skin cap.   The process is fast, gentle and helps maintain wine quality during crucial red fermentation.  Winemakers can both improve quality while simultaneously reducing labor costs, reducing maintenance & cleaning cost during harvest and fast year-round blending for any type of tank mixing with compressed gases.

This innovative and proven air mixing process for efficiently managing red grape skin caps during primary wine fermentation and wine blending is used all over the world by hundred of winemakers to make better tasting wines. 

This efficient wine cap air mixing technique works by sequentially 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 gently enhance the infusion of phenolics, flavor, tannins and color into the juice.

The air or gas pulses can be injected into the tank over the top of an open tank with a portable mixing probe, through a racking port ball valve or from multiple fixed or removable air injection ports through the tank walls or tank floor bottom.

This process maintains freshness, reduces bacteria formation and helps expel unwanted wine mercaptans, CO2 gas and reductive volatile sulfur compounds for a more healthy and less reductive tasting wine.

Also known as ‘in-tank pump-over’ or a ‘reverse wine punch down’, the Pulsair ‘pneumatage’ process is the fastest and most efficient method to manage red grape caps. 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.
