When I first spoke with this customer, a global manufacturer producing everything from everyday mixers to top-shelf spirits, they had a clear goal: tighten their filling process to eliminate MAV (Maximum Allowable Variation) violations and reduce overfill waste, without compromising quality.

Like many high-volume producers, they knew small inefficiencies add up fast. Even a fraction of a percent in overfill meant lost product, lost profit, and unnecessary risk. They needed real-time visibility and control—and that’s where Minitab Real-Time SPC came in.

The SPC Assessment

We started with a focused proof of concept at their Toronto, Canada site on one filling line. Using Minitab Real-Time SPC, the team collected check sheet data covering quality, safety, and packaging. The goal was simple: see whether real-time monitoring could help operators catch issues before they became costly problems—and it did.

Why the Distillery Chose Minitab

Ease of use was a big factor. Operators quickly saw value in a system that standardized data collection, sent instant notifications when something drifted out of spec, and made management data accessible with just a few clicks.

A few moments stood out during the trial:

• Real-time alerts helped an operator spot mismatched divider trays before packaging, avoiding a product hold and costly rework.
• Electronic check sheets made it simple to capture SIP/CIP and verification data.
• Instant reporting gave the team new visibility into fill performance and content control.

And perhaps most importantly, the data revealed a huge opportunity: by fine-tuning their overfill, they could save thousands per week without risking a single MAV violation.

After adjusting targets and running another controlled trial, the numbers told the story: zero MAV violations, overfill under 1%, and substantial savings that proved the business case for expansion.

After implementation of the proof of concept, 200 subgroups of 5 samples were monitored for net content. The following results were obtained from production of their 750 ml single malt, with the UpperMAV and LowerMAV of 765-735:

With their initial goals met: zero MAV violations and less than 1.0% overfill, the team turned their attention to what else was possible. A quick analysis revealed a new opportunity: a 0.5% reduction in overfill could dramatically boost savings. Armed with that insight, they refined the target, tuned the equipment, and conducted another data run of 200 subgroups to measure the improvement.

Final Observations

When the team adjusted the target to 751.87, the results spoke for themselves. The product stayed comfortably within MAV, and one production line alone uncovered a potential savings of $18,000 every week. Multiply that by 48 production weeks, and you have $864,000 in annual savings—just from one line of the premium 750ml single malt.

What started as a proof of concept quickly became something bigger. Success lit a spark across the company, proof that data, when used in real time, can transform not just a process, but a culture. With Minitab Real-Time SPC, the distillery is now extending this approach beyond the filling line to include bottle prep, labeling, packaging, the lab, and quality areas.

The next chapter isn’t just about rolling out new software; it’s about reimagining how decisions are made. Every operator, engineer, and quality specialist will soon have the power of live data at their fingertips, turning insights into action instantly. This is about more than craftsmanship; it’s about precision, progress, and the pursuit of operational excellence, one data point at a time.
