Many breweries and beverage producers are expanding into RTD (ready-to-drink) beverages to diversify their offerings and better utilize existing equipment through contract packaging.
Unlike beer, RTD beverages are typically blends of water, flavors, sugars, and functional ingredients, with carbonation levels ranging from still (0 volumes) to 2–3 volumes CO₂. These products often have Total Package Oxygen (TPO) specifications between 50 ppb and 2 ppm, depending on sensitivity and shelf-life requirements.
Maintaining tight control of dissolved oxygen is critical to producing a stable, high-quality RTD product.
Why Dissolved Oxygen Matters in RTD Beverages
Excess dissolved oxygen can lead to:
- Oxidation of flavors and aromas
- Color degradation
- Reduced shelf life
- Inconsistent product quality
In traditional brewing, oxygen is naturally reduced during fermentation and managed through proper tank practices. However, RTD production introduces new oxygen risks, especially through blend water.
Common Deaeration Method: CO₂ Sparging
One widely used approach is carbon dioxide sparging using a carbonation stone.
Pros:
- Uses existing brewery equipment
- Simple to implement
Limitations:
- Requires large volumes of CO₂
- Long processing times (often 8–10 hours per tank)
- Can become a production bottleneck
For growing RTD operations, this method can significantly limit throughput and increase operating costs.
A More Efficient Solution: Membrane Deaeration
Membrane contactors have been used for over 30 years in beverage and water treatment applications. Many large breweries already rely on them for high-gravity brewing and dilution water deaeration.
Key advantages:
- Inline, continuous operation
- Works across a wide range of temperatures and flow rates
- Achieves very low dissolved oxygen levels
- Provides on-demand deaerated water
This allows producers to eliminate long tank processing times and dramatically increase packaging capacity.
ROI of Deaeration Systems for RTD Production
Investing in a dedicated deaeration system can deliver fast returns through:
- Improved product quality and consistency
- Reduced CO₂ consumption
- Increased production throughput
- Lower labor and tank utilization time
For beverage producers scaling RTD production, deaeration is not just a quality step—it’s a capacity unlock.
Choosing the Right Deaeration Approach
The best solution depends on:
- Production volume
- Oxygen specifications (TPO targets)
- Available utilities (CO₂, vacuum, etc.)
- Desired level of automation
Modern deaeration skids and membrane systems offer a compact, efficient way to integrate oxygen control directly into your process.

Frequently Asked Questions: RTD Beverage Deaeration – How to Control Oxygen and Improve Shelf Life
Deaeration is the process of removing dissolved oxygen from water or beverage blends before packaging. In RTD production, it is typically applied to blend water to reduce total package oxygen (TPO) and improve product stability, flavor, and shelf life.
Acceptable oxygen levels vary by product, but most RTD beverages target TPO levels between 50 ppb and 2 ppm. More sensitive products—such as those with natural flavors, vitamins, or functional ingredients—require lower oxygen levels to prevent oxidation and quality degradation.
Dissolved oxygen can be removed using several methods, including:
- CO₂ sparging (carbonation stones)
- Vacuum deaeration systems
- Membrane contactors (membrane deaeration systems)
Membrane deaeration is often preferred for RTD production because it provides continuous, inline oxygen removal with faster processing times and lower gas usage.
While CO₂ sparging is simple and uses existing brewery equipment, it has several drawbacks:
- High CO₂ consumption
- Long processing times (often 8–10 hours per tank)
- Inconsistent oxygen removal
- Reduced production capacity due to tank downtime
These limitations make it less efficient for high-volume or growing RTD operations.
Membrane deaeration systems offer several advantages:
- On-demand, inline operation (no long tank holds)
- Lower dissolved oxygen levels for tighter quality control
- Reduced CO₂ usage compared to sparging
- Increased throughput and production efficiency
For many beverage producers, membrane systems provide a faster return on investment by improving both product quality and operational capacity.
