Pulsair Wine Tank Mixing

Since 1986, winemakers have used Pulsair’s “pneumatage” air mixing process to mix red grape juice quickly and efficiently into contact with the floating skins. 

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 enhance the extraction of flavor, tannins and color into the juice. 

This process maintains freshness, reduces bacteria formation and helps expel unwanted wine mercaptans, CO2 gas and 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.

 

Applications


Wine Cold Soak Management

Pre-fermentation cold soak wine is a technique some winemakers employ for a few days prior to inoculating the ferments for Pinot and other reds. The goal is to encourage more color and flavor extraction from the skins into the juice. In which, whole or crushed berries and juice are put into stainless steel fermentors with dimpled cooling jackets. In addition, Glycol and water is then pumped through the jacket to lower the temperature to the desired point.  Without proper stirring of the wine uneven temperatures and hot spots can compromise the cold soak process. Pulsing compressed inert gases into the tank below the cap with Pulsair is a quick and easy way to bring the juice up over the top of the cap to enhance this process and maintain a uniform temperature in the tank. The Pulsair mixing tank technique saves time, reduces labor costs and keeps the caps loose and broken up into individual berries to make normal cap management.

Wine Pump Over

Wine pump over, also referred to as ‘remontage’ in France, is a process in which red wine juice is pumped from the bottom of the fermentation tank through a hose and then sprayed and splashed over the top of the grape cap must in order to bring the juice in contact with the skins so the color, flavor and aromas can be extracted from the skins into the juice.  The wine pump over process is usually employed in large closed and open top red wine fermenters during the main red wine fermentation process.

Pneumatage, or also simply known as ‘pulsair’, is a similar process in which the wine juice makes contact with the wine cap but differs in the fact that the wine juice is brought up and over the cap through the use of pulsing large burst of compressed air through a stainless steel mixing probe or fixed injection port probes near the bottom of the wine fermentation tank.  The rising bubbles break up the cap into individual berrries and the wine juice spills up and over the top.

While at the high level, the two process accomplish the same thing: cap management, there are so many more advantages to the winemaker during this critical wine making process.

Wine Cap Management 

Pulsair offers wine fermentation accessories used for cap management wine and lees management.
Once we have crushed the fruit, it’s time to start the wine fermentation. White wines need to be protected from oxygen and are usually fermented in a closed vessel. Red wines actually benefit from oxygen exposure during fermentation and are often fermented in open-top vessels.

To achieve the best fermentation, Pulsair offers a wide range of wine mixing systems and agitators,

  • Portable Wine Tank Mixer
  • Oil Free Air Compressors
  • PPC Pneumatage
  • Wine Cart
  • Crush Cart

Wine Blending

Wine Blending is the operation where two different lots of wine are combined. The wine lots can be different single-varietal wines, two already blended wines , at least two wine lots that are the same varietal, or even two wine lots of same varietal and vineyard. 

In order to get the best wine blending Pulsair offers winemakers a simple and efficient method. This fast wine blending process uses bursts of compressed air, nitrogen or CO2 gases sequentially released at the tank bottom to quickly blend two or more different wines.  Winemakers can also blend in other additives to their wines to quickly create their desired wine.

Sturring the Lees

Sur lie aging is the process of allowing a finished wine to continue to sit on the lees in order to extract flavors.

Stirring the lees is a process in which leftover yeast particles that settle on the tank or barrel bottom are stirred up and gently agitated in white and sparkling wines.  This “sur lie aning” process is known to add textures and flavors to the wine.  It is believe that white wines that are fermented and aged in lees are often described as having greater depth, richer, creamer and fuller-bodied flavors.

Pulsair wine mixing tank Systems has simple solutions for stirring the lees in barrels and large white fermentation tanks. The process works by releasing large compressed air/gas bubbles close to the tank floor.  These bubbles gently disturb the settles less and bring them up into suspension as the large bubbles rise to the wine surface.  Pulsair can design custom solutions based on the tank size and specific requirements and goals of the winemaker.

" 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. "
