Oxygenation Bung for Barrel Aging
Overview
The AirBung™ is a precision-engineered oxygenation bung designed to bring oxygen control into the craft of barrel aging. Built from white oak and featuring a thin polymer film (TPF), an AirBung lets distillers manage oxygen ingress independently from evaporation control. It turns a passive element of aging into a tunable variable.
Key Features
- Oxygen-Selective
Uses an ultra-thin polymer film with customizable thickness and surface area to precisely control oxygen flow. - White Oak Construction
Built from traditional materials while offering modern functionality. - No Power or Equipment Required
Installs like a standard bung; no pumps, hoses, or electronic controls needed. - Full Maturation Cycle Compatibility
Functions consistently throughout the entire aging process.
Technical Advantages
Decouples Evaporation from Oxidation
Preserve spirit volume while achieving oxidative benefits.
Custom Flavor Development
Fine-tune oxygen ingress to influence aroma, texture, and finish—tailoring each cask to your target profile.
Improved Barrel Consistency
Reduce variability in oxygen exposure across barrels for more uniform results.
Yield Protection
Minimize angel’s share losses without compromising maturation quality.
Faster Time-to-Market
Accelerate flavor development while maintaining depth and balance.
How It Works
At the core of the AirBung is a polymer-based system that selectively allows air (oxygen) to pass. Adjusting the membrane’s thickness and area lets distillers set an oxygen ingress rate tailored to each cask. This provides unprecedented control over maturation, enabling innovation without disrupting standard workflows.
Who It’s For
The AirBung is ideal for:
- Craft distilleries seeking flavor consistency
- Researchers running controlled barrel trials
- Producers looking to optimize yield and maturation time
- Innovators aiming to modernize traditional practices
Ready to Integrate
AirBung is available in multiple configurations for 5- to 52-gallon barrels. No special equipment is required—just swap the bung and start recording results.
