AlcoTECH

Alcohol Adjustment Technology

AlcoTECH alcohol adjustment technology allows you to fine tune your wine to produce the perfect blend at the required alcohol level.

AlcoTECH alcohol adjustment functions on the principle of low temperature evaporation under high vacuum, coupled with modern distillation technology at Tarac’s Nuriootpa facility in South Australia.

Vintage and blending options are available, allowing winemakers to fine tune individual components throughout any stage of the winemaking process, creating tailor made winemaking solutions.

AlcoTECH provides additional options to current technologies available.

Key Advantages

• No loss to aroma or complexity (statistically proven results)
• Competitive pricing
• Laboratory testing of samples prior to processing to determine desired alcohol level
• Only small portions of blend volume required for treatment – typically less than 10% of total blend
• Fast turnaround – able to treat a large blend in approximately 24 hours
• Environmentally friendly system with all residual products remaining at Tarac, freeing up tank space and reducing loads on winery waste water systems.
• Vintage option allows you to manage alcohol blend at the crusher. It removes the need for post vintage alcohol reduction and reduces attenuated ferment characters, dilution of flavour and possibility of stuck ferments.
• AlcoTECH outputs create blending options, where portions can be blended to alter alcohol, phenolic and acidity profiles.
• Maintains Label integrity Program (LIP)

The AlcoTECH System

Vintage Option

Allows the winemaker to balance the alcohol/wine concentration levels from the first crush of the Vintage.  When performed on early wines and used as a blending option on high Baume juices, it allows the winemaker to achieve desirable alcohol content in finished wine.

 

Vintage Option Wine produced early in vintage has all EtOH removed.  Wine at 10% EtOH used at crusher to lower Be.

Impacts Achieved lower probability of stuck ferments reduces attenuated ferment characters desirable EtOH% achieved early, aids Classification no dilution of flavour compared to condensate or LSJ additions maintains Label Integrity program (LIP) provides integration of the blend at pre-fermentation stage no need for post vintage EtOH removal

Example

• 10T of grapes crushed and fermented to yield approximately 7.5KL of wines
• 7.5KL of wine treated to remove ethanol to yield approximately 6KL of 0% wine
• 6KL of 0% wine added to 54KL of juice at 15Be -> 13.5Be in final blend of 60KL
• 60KL blend fermented to dryness producing a wine at around 13.5% EtOH (instead of 15%)
  
  

Blending Option

Allows the winemaker to fine tune the phenolic, acidic and alcohol content of finished wines.
