Froth Technologies: Scaled Yeast Quality and Production Confidence

Real-time fermentation intelligence helps New Zealand’s only domestic liquid yeast producer increase yield, save labor, eliminate guesswork, and deliver consistent results to brewers nationwide

Customer Snapshot

Company: Froth Technologies

Location: New Zealand

Focus: Liquid yeast production for craft breweries

Team Size: 3-person production team

Production Model: Continuous, multi-stage yeast propagation

As New Zealand’s first and only domestic liquid yeast producer, Froth Technologies is dedicated to unlocking local flavor through fermentation. By cultivating wild and proprietary yeast strains sourced from New Zealand’s natural environments, Froth Technologies supplies brewers with fresh, high-quality yeast pitched directly into fermentation tanks—eliminating the need for additional propagation at the brewery level.

Despite being early in their growth, Froth Technologies quickly became a critical supplier to the country’s craft beer scene, earning national awards and industry recognition. But scaling a biologically sensitive process with a lean team introduced new operational pressure.

The Challenge: Maintaining Precision in a Continuous Fermentation Workflow

Froth Technologies’s yeast propagation process operates as a three-stage, continuous system—from lab culture to initial propagation to final production tanks. With multiple batches running simultaneously and each stage tightly dependent on the next, timing and consistency are everything.

Before adopting Sennos, Froth Technologies relied on manual sampling twice per day, collecting gravity, pH, temperature, dissolved oxygen, and cell data to estimate fermentation progress. While effective in snapshots, this approach left long gaps between measurements.

“You’re working with a living organism inside a stainless steel tank,” explains Ryan Carville, Co-Founder at Froth Technologies. “Without continuous visibility, it’s hard to know whether you’re pushing things too fast, too slow, or missing early warning signs.”

Key challenges included:

• Limited visibility between manual checks
  

• Conservative tank scheduling to avoid risk
  

• Occasional batch losses due to late detection
  

• Weekend and off-hour site visits for peace of mind
  
  

The Sennos Solution: In-Tank Intelligence, Always On

Froth Technologies implemented the SennosM3 modular fermentation monitoring system across their production tanks, using Sennoslink as the operational interface and SennosIQ for fermentation intelligence and benchmarking.

The SennosM3 sensor array continuously monitors:

• Density (gravity) to track fermentation progress
  

• pH to ensure yeast health and detect anomalies
  

• Temperature & pressure to maintain optimal growth conditions
  

• Dissolved oxygen during critical propagation phases
  

All data streams directly to Sennoslink, giving the team real-time visibility from anywhere, with historical data automatically organized by batch and process stage. As more fermentations were logged, SennosIQ layered in benchmarking and intelligent alerts, allowing Froth Technologies to compare current runs against proven profiles.

“Instead of guessing what’s happening between samples, we can see the full fermentation curve unfold in real time,” says Carville. “That changed how confident we are in making decisions.”

The Results: Higher Yield, Less Labor, Greater Confidence

With continuous in-tank monitoring, Froth Technologies was able to tighten their production timelines and push tanks more efficiently—without increasing risk.

Measured outcomes include:

• Up to 15% increase in yield per batch, equivalent to approximately $30,000 (NZD) annually
  

• 5–6 hours of labor saved per week by reducing manual sampling and site visits
  

• Fewer dumped batches, thanks to early deviation detection
  

• More consistent yeast quality, batch to batch
  

Sennos also reduced the need for weekend commutes. Instead of driving 30 minutes to check a tank, the team could review fermentation status remotely and make adjustments with confidence.

“Now we can see exactly where the fermentation is at, even from home,” Carville notes. “That’s better for our process, our sustainability goals, and our work-life balance.”

Consistency That Scales Downstream

Beyond internal efficiency, Sennos helped Froth Technologies deliver a more consistent product to their brewery customers.

“It’s all about consistent ingredients and a consistent process,” says Carville. “By ensuring each fermentation follows the same expected curves, our customers receive yeast they can rely on. That means more consistent beer for them, batch after batch.”

The detailed digital records generated through Sennoslink and SennosIQ also support quality assurance, customer communication, and brand credibility—critical for a supplier operating at the center of the brewing ecosystem.

Takeaway

For Froth Technologies, Sennos isn’t about automation for its own sake—it’s about confidence. Confidence to scale production without adding staff. Confidence to push tanks efficiently. Confidence that every batch meets the same high standard.

By turning every tank into a smart tank, Sennos helped Froth Technologies unlock measurable gains in yield, time, and peace of mind—while preserving the craft and care that define great fermentation.
