Case Study: Kaesler Wines reduces energy consumption by 52%.
Kaesler Wine’s adoption of Frigid.Cloud has delivered standout results in both energy efficiency and operational control. With vintage-time pressures and energy costs rising, the system helped Kaesler cut energy use dramatically while improving winemaking oversight. The figures below speak for themselves—and make a compelling case for smart cooling as a high-impact investment.

In February 2025, Kaesler Wines adopted Frigid.Cloud to elevate both its energy efficiency and operational oversight during vintage. In May, a detailed energy analysis was conducted to measure the impact of the system, revealing remarkable reductions in site-wide energy consumption and daily cost savings.
Background
Kaesler Winery processes a different volume of grapes each vintage. The tonnes crushed over the last three years were:
- 2023: ~500 tonnes
- 2024: ~300 tonnes
- 2025: ~500 tonnes
For a fair comparison, data from an 30-day period—characterised by consistent cooling demands and similar ambient temperatures—was selected for energy usage analysis.
Energy Usage & Efficiency Gains
Site-wide energy use (30-day comparison):
- 2023: 16,607 kWh
- 2024: 12,810 kWh
- 2025: 6,156 kWh
Despite a 66% increase in production from 2024 to 2025, Kaesler saw an overall 52% reduction in energy consumption after implementing Frigid.Cloud. Importantly, this figure represents total site usage—not just the chiller system.
This significant reduction is credited to Frigid.Cloud’s pulse cooling and proactive batch cooling strategies, which prioritise energy optimisation while maintaining tight temperature control.

Financial Impact
The reduction in energy consumption delivered measurable cost savings in 2025 when compared to the average of the previous two years:
- 66% daily average reduction from expensive peak electricity periods.
- 56% daily average reduction of outside of peak electricity periods.
- Total average daily saving of 59%
These savings contribute to a fast return on investment while reducing operational stress during vintage.
🚀 Operational Efficiencies
Beyond energy savings, Frigid.Cloud introduced key operational advantages that proved especially valuable during vintage, when precision and reliability are paramount:
- Real-Time Remote Monitoring: Winemakers and operators now have visibility into tank and glycol performance from any device, anywhere. This real-time oversight provides critical assurance during high-pressure periods.
- Automatic System Response: If the glycol system fails or starts to warm up unexpectedly, the tanks automatically isolate themselves—preventing warm glycol from circulating and causing wine spoilage. This proactive response helps mitigate risks before they escalate.
- Intelligent Alerts: Built-in alerting notifies the team if tank temperatures begin trending out of specification. Early warning allows for quick intervention, avoiding quality issues or product loss.
- Remote Control: Temperatures can be adjusted remotely, saving time and reducing the need for physical site visits—especially helpful during night shifts or weekends.
“Having remote access to every tank and knowing the system is responding before we even notice a problem is a game changer during vintage.”
Tim Dolan, Chief Winemaker
How Frigid.Cloud works
Frigid.Cloud enhances efficiency through two key methods:
- Proactive Cooling: Instead of reacting to individual tank demands, the system evaluates all tank requirements and batches them for cooling. This allows the chiller to operate more efficiently and creates windows of downtime.
- Pulse, Lock & Hold Strategy: After batch cooling, tanks maintain their temperature by pulsing glycol in sync with the system’s thermal profile. This avoids overcooling and excessive energy use while protecting wine quality.
“Over the past couple of decades, the vineyard team at Kaesler has been dedicated to improving soil carbon levels, enhancing biodiversity, and reducing our carbon footprint. The introduction of Frigid.Cloud marks the next step in extending our commitment to environmental stewardship from the vineyard into the winery.”
