Pneumatage - Innovative solutions for red wine fermentation & wine blending

"Pneumatage" is an innovative and proven method for efficiently managing grape skins caps during red wine fermentation and wine blending. Pulsair System's Pneumatage process is used by hundreds wineries around the world to automate their cap management or compliment current cap management techniques.

The Pneumatage process works by pulsing large bubbles of compressed air or gas near the bottom of the fermentation tank. The rising bubbles provide uniform temperature distribution, keeps yeasts healthy and efficiently wets the cap to enhance the extraction of flavor, tannins and color into the juice.

This process is an excellent method for flooding wine caps to maintain freshness, reduce bacteria formation and helps expel unwanted wine mercaptans and volatile sulfur compounds. Unlike other methods, Pneumatage breaks up the cap into individual berries and then circulates them in the juice. Utilization of Pneumatage during the initial phases of the fermentation keeps the cap in a semi-loose state making it easier and more efficient to periodically conduct the Pneumatage.

"Wine by Joe uses Pulsair for the vast majority of cap management. From 1.5 ton bins to 35 ton tanks Pulsair efficiently mixes cold soaks and active fermentations with less physical labor. This gentle method of incorporating the cap helps to minimize sulfides and astringent tannins and easily distributes heat and juice. In the future we're looking into applying our Pulsair units with nitrogen outside of the harvest season to mix tanks of wine, further reducing labor by cutting down on pump set up time."

"The Pneumatage mixing process allows us to minimize and avoid the formation of mercaptans and other complex sulfides by adequately aerating the grape juice and caps during fermentation. This helps us control the fermentation process and produce a better tasting wine."

"The PTM Pneumatage unit we have is a great winemaking tool. The time it takes to execute a pump over is reduced to 30-seconds with this portable unit. You can't beat the quick addition of air to our red ferments - keeps the yeast happy, makes us happy!"
