More Beer Without More Tanks: How a Brewery Centrifuge Can Increase Cellar Capacity
Share
As brewery production grows, the next bottleneck is not always the brewhouse.
Sometimes it is the cellar.
Beer may be ready from a fermentation standpoint, but the tank remains occupied while yeast and suspended solids slowly settle.
That waiting period affects more than clarification.
It affects:
- Fermenter availability
- Production scheduling
- Beer recovery
- Packaging timing
- Overall cellar capacity
This is where a beer centrifuge can change the production model.
The Redwood Craft Beer Centrifuge uses high-speed disc stack separation to remove yeast, cold break, protein particles, and suspended solids much faster than natural settling, while helping minimize oxygen pickup during clarification.
For growing breweries, the value is not simply clearer beer.
It is the ability to move beer through the cellar faster and get more production from the equipment already in place.
1. More Beer Without More Tanks
When production demand increases, the first reaction is often:
We need more fermenters.
Sometimes that is true.
But before adding more tanks, it is worth asking whether existing tanks are being occupied longer than necessary because beer is waiting to clarify.
Traditional gravity settling can keep beer in fermentation vessels for additional time after fermentation is complete. The Redwood Craft Beer Centrifuge is designed to shorten that clarification stage, helping breweries increase fermenter utilization and overall cellar efficiency.
That means a brewery may be able to move finished beer out of the tank sooner and prepare the fermenter for the next batch.
The result is not a larger cellar.
It is a more productive one.
Why this matters
Adding fermentation tanks affects more than equipment cost.
It may also require:
- Additional floor space
- Glycol capacity
- Piping
- Controls
- Cleaning capacity
- Installation work
- Future maintenance
If faster clarification can improve tank turnover, the brewery may be able to increase production capacity before expanding the cellar.
2. Package Beer Earlier
Natural settling works, but it takes time.
For breweries with growing production schedules, waiting days for beer to clarify can become a constraint.
A disc stack centrifuge uses centrifugal force to separate yeast and suspended solids from the beer much faster than gravity alone. Redwood's centrifuge is designed for continuous clarification and is available in capacities ranging from 2 to 15 tons per hour.
That allows clarified beer to move to the next production stage sooner.
Depending on the brewery process, that may include:
- Conditioning
- Bright beer storage
- Filtration
- Packaging
The operational benefit is simple:
Less time waiting for clarification means more flexibility in production scheduling.
For breweries packaging on tight schedules, earlier clarification can also make it easier to coordinate tank availability with the canning line
3. Reduce Beer Losses
Yeast sediment does not contain only yeast.
It also contains beer.
When beer is allowed to settle naturally, some finished product can remain trapped in the yeast slurry and be lost during tank transfers or dumping.
A centrifuge separates suspended solids from the beer mechanically, allowing breweries to recover more saleable beer from the clarification process.
Redwood's system is designed to remove:
- Yeast
- Cold break
- Protein particles
- Fine suspended solids
Residual yeast concentration after separation can be reduced to approximately 2 million cells/mL, depending on beer type and operating conditions.
For breweries producing at scale, small improvements in recovery can become meaningful across repeated batches.
The objective is not simply to make beer brighter.
It is to move more of the beer you already produced into the finished package.
4. Improve Batch-to-Batch Consistency
Natural clarification can vary.
Settling behavior may change depending on:
- Yeast strain
- Beer style
- Temperature
- Tank geometry
- Time
- Solids load
A centrifuge gives the brewery a more controlled clarification step.
Instead of relying only on time and gravity, the process uses mechanical separation to consistently remove suspended solids from the beer.
That can help improve:
- Clarity consistency
- Production repeatability
- Downstream process stability
- Packaging preparation
For breweries producing the same brands repeatedly, this consistency can make production planning more predictable.
It can also reduce the variation operators have to manage from batch to batch.
5. Protect Fresh Hop Aroma
Clarification speed matters.
But for many craft breweries, beer quality matters even more.
Oxygen exposure during processing can contribute to:
- Loss of hop aroma
- Faster flavor deterioration
- Reduced freshness
- Shorter shelf life
This is especially important for hop-forward beers.
The Redwood Craft Beer Centrifuge is designed to reduce oxygen pickup during clarification through a combination of:
- Low-shear feeding
- CO₂ inert gas protection
- Deoxygenated sealing water
- Pressurized sealing structure
Under recommended operating conditions, dissolved oxygen pickup can remain below 5 ppb.
The low-shear feeding system is also designed to minimize turbulence and help protect hop aroma, foam stability, protein structure, and mouthfeel.
This matters because clarification should not solve one production problem while creating another.
The goal is to remove solids while preserving the beer characteristics the brewery worked to create upstream.
6. Why Low-Shear Handling Matters
A centrifuge operates at high rotational speed internally.
But that does not mean the beer should be handled aggressively on the way into the separator.
Excessive turbulence during product transfer can affect:
- Foam stability
- Aroma
- Protein structure
- Mouthfeel
That is why Redwood uses a low-shear feeding design to reduce unnecessary turbulence during product transfer.
For delicate beers, especially hop-forward styles, this helps support product quality throughout the clarification step.
The clarification process should be fast.
The beer handling should still be gentle.
7. A Centrifuge Can Reduce the Load on Downstream Filtration
A centrifuge does not automatically replace filtration in every brewery.
The right process depends on:
- Beer style
- Clarity target
- Production method
- Downstream equipment
Some breweries use centrifugation as the primary clarification step.
Others place the centrifuge before filtration to reduce solids loading and extend filter life.
The important point is that clarification should be evaluated as part of the complete brewery process.
A centrifuge can change not only tank turnover, but also the workload placed on downstream equipment.
8. More Automation, Less Operator Intervention
Cellar efficiency is not only about tank availability.
It is also about how much operator attention the process requires.
The Redwood Craft Beer Centrifuge includes:
- Automatic PLC control
- Variable frequency drive
- Automatic sludge discharge
- Automatic CIP
- Automatic vibration monitoring
This allows the separator to operate as a continuous automated clarification process rather than a highly manual production step.
Routine cleaning is also supported through the integrated automatic CIP system.
When Does a Brewery Centrifuge Make Sense?
A centrifuge may be worth evaluating when:
- Fermenters remain occupied while beer waits to clarify
- Production demand is increasing
- Cellar capacity is becoming a constraint
- Beer losses from yeast sediment are becoming significant
- Clarification results are inconsistent
- Packaging schedules require faster tank turnover
- Low dissolved oxygen is a production priority
- The brewery wants to delay or reduce additional tank expansion
Redwood's centrifuge range supports capacities from 2 to 15 tons/hour, making the technology relevant to growing craft breweries as well as larger commercial operations.

Before Adding More Fermenters, Look at Tank Utilization
The question is not:
Do we need more tanks?
The better question is:
What is keeping the tanks occupied?
If fermentation itself is the bottleneck, additional cellar capacity may be necessary.
But if tanks are spending significant time waiting for natural clarification, improving the clarification process may create additional production capacity without immediately expanding the tank farm.
That is where centrifugation becomes more than a beer-clarity tool.
It becomes a production-capacity tool.
More Beer. Faster Tank Turnover. Better Product Recovery.
A brewery centrifuge can affect several parts of the operation at the same time:
More Beer Without More Tanks
Improve fermenter turnover and get more production from existing cellar equipment.
Package Beer Earlier
Clarify beer in hours instead of waiting days for natural settling.
Reduce Beer Losses
Recover more finished beer from yeast slurry and improve production yield.
Consistent Beer Quality
Create a more repeatable clarification process from batch to batch.
Protect Fresh Hop Aroma
Reduce oxygen pickup during clarification to help preserve freshness and delicate hop character.
For a growing brewery, these benefits can make clarification a strategic part of production planning rather than simply the final step before packaging.
