The Client, a multi-site brewing operation producing 1–5 million hL/year per site, was experiencing declining process performance that was impacting both profitability and brand quality. Inconsistent fermentation performance, inefficient centrifugation practices, and suboptimal yeast management were driving variability in flavor stability, increased operating costs, and reduced brewhouse yield. Core brands showed sensory defects, including thin body and lack of fullness, weakening competitive positioning and limiting premium growth opportunities.
First Key conducted a comprehensive technical assessment across three breweries and implemented a targeted improvement program focused on fermentation optimization, yeast management, and centrifuge efficiency. Fermentation conditions were refined to improve flavor stability and consistency, while centrifuge operating parameters were reconfigured to enhance separation efficiency and reduce reprocessing. Yeast propagation practices were upgraded to improve viability and reduce cycle time. In parallel, sensory analytics and formulation work were applied to strengthen core brand profiles and support the development of new products positioned for premium segments.
The engagement delivered measurable improvements in both operational performance and product quality:
• Brewhouse yield increased from 95.8% to 97.6% (+1.8 points)
• Centrifuge discharge cycles reduced by 33%, eliminating double centrifugation
• Kieselguhr usage reduced by up to 15%, lowering filtration costs
• ~40% improvement in SO2 management, strengthening flavor stability
• Core brands demonstrated improved sensory performance, correcting prior body and mouthfeel deficiencies
• New product concepts achieved top-tier sensory performance vs. imported benchmarks
These improvements reduced avoidable operating costs, improved process consistency, and strengthened product competitiveness, while also creating a foundation for innovation-led premium growth.
