Craft Brewery Improves Product Quality, Cuts Costs 58%
Right-sized nitrogen system handles seasonal demand variations perfectly
The Challenge
A well-established Sacramento craft brewery producing 15,000 barrels annually was facing rising nitrogen costs and operational challenges:
Nitrogen applications:
- Can and keg purging (oxygen elimination)
- Widget beer production (nitro stouts and porters)
- Packaging line pressurization
- Tank blanketing and transfers
- Draft system pressurization
Problems with delivered nitrogen:
- Inconsistent supply impacting quality
- High costs during peak production (summer/fall)
- Seasonal demand variations made sizing difficult
- Multiple cylinder deliveries per week during busy season
- Quality concerns with oxygen contamination
Annual nitrogen cost: $32,400 (delivered cylinders)
“We were going through 8-12 cylinders a week during peak season and maybe 3-4 in winter. The cost was killing us, but worse was worrying about running out during a canning run and ending up with oxidized beer.”
— Head Brewer
Our Measurement-First Approach
Craft breweries have unique seasonal demand patterns that standard sizing calculations miss. We measured actual consumption across a full production cycle:
90-day data logging revealed clear patterns:
Peak Season (July-October):
- Average demand: 68 SCFM (high production volume)
- Peak during canning: 95 SCFM (4-6 hour runs, 2-3x per week)
- Daily usage: 16-22 hours of nitrogen needed
Off-Season (November-March):
- Average demand: 28 SCFM (reduced production)
- Peak during packaging: 55 SCFM (smaller runs)
- Daily usage: 8-12 hours typical
Shoulder Season (April-June):
- Gradual ramp-up: 35-50 SCFM average
- Building inventory for summer demand
Critical insight: A system sized for peak demand would be massively oversized 60% of the year, but too small would create the same supply problems they already had.
The Right-Sized Solution
We designed a system that efficiently handles seasonal variations:
- Primary generator: 80 SCFM membrane system (99.5% purity)
- Smart turn-down: Efficient operation at 30-100% capacity
- Purity perfect for brewing: 99.5% eliminates oxygen contamination
- Pressure control: Optimized for packaging equipment
- Buffer storage: 240-gallon receiver tank smooths peak demands
- Backup cylinder connection: Insurance for rare extreme peaks
Investment: $32,400 installed
- Operating cost: $13,600/year (electricity, maintenance, monitoring)
- vs. Delivered nitrogen: $32,400/year
- Annual savings: $18,800/year
Results & ROI
Financial Impact:
- Operating savings: $18,800/year
- Consistent costs year-round (no seasonal spikes)
- Payback period: 21 months
- 5-year savings: $94,000
- 10-year NPV: $156,000
Quality Improvements:
- Zero oxygen contamination issues (previously 2-3 batches/year affected)
- Consistent nitrogen purity for widget beers
- No rushed packaging due to nitrogen concerns
- Better shelf stability and product consistency
Operational Benefits:
- Package when you want, not when nitrogen arrives
- No delivery scheduling or coordination
- No cylinder storage taking up brewery floor space
- Can take on contract canning work confidently
- Eliminated “cylinder anxiety” during big releases
The Quality Factor
Beyond cost savings, consistent nitrogen improved their beer:
Before: Delivered Nitrogen
- Occasional quality issues from low cylinder pressure
- Rushed packaging when running low
- Inconsistent purge quality
- 2-3 batches per year with shelf-life concerns
After: On-Site Generation
- Consistent purity every packaging run
- Relaxed packaging schedule = better QC attention
- Zero oxidation issues in 12+ months
- Confident shelf-life predictions
- Better customer reviews and lower returns
“The ROI was good on paper, but the real win was product quality. We haven’t had a single oxidation issue since installation. Our shelf life improved, our ratings improved, and we can focus on brewing instead of worrying about nitrogen.”
— Head Brewer
Seasonal Efficiency: The Right-Sizing Advantage
What if they’d bought an oversized system?
A 150 SCFM system (typical vendor recommendation with “safety margin”):
- Capital cost: $52,000 (61% more expensive)
- Energy waste in off-season: ~$3,000/year (operating inefficiently)
- Longer payback, same capacity when actually needed
Our measured approach:
- Perfect capacity for actual peak demand
- Efficient operation at all production levels
- Lower capital cost, faster payback
- Same reliability and quality
Key Takeaway
“Craft breweries have wild seasonal swings. The national vendors wanted to sell us a huge system ‘just to be safe.’ The data logging showed we needed half that size. We saved money upfront, we save on power year-round, and the beer is better. That’s a win-win-win.”
