Brewing Science Heaven!
I’ve been listening to beer podcasts for well over a decade now, and MBAA's podcast is by far the best for getting the most succinct brewing industry technical knowledge! This podcast sold me on finally getting a membership with the MBAA too. Yeah, the audio/production quality for the first several episodes were garbage (when not being a brewer, I’m a broadcast journalist with the Air National Guard), but it’s much better now. Keep that in mind for the first several if you find your face conform... more

The best beer education out there
I love attending CBC and watching BA, ASBC and MB webcast seminars, but IMHO, this is the most educational 30 - 40 minute investment a pro brewer can make. Episode after episode is packed with valuable information.

Episode 240: Understanding the Risk of Can Pressure Failures (Feb 2022)

Q: What practical steps should a brewery take when applying these findings to real-world canning and pasteurization processes?

Develop a visual, color-coded reference tool tailored to your container's exact PSI rating and your product's CO2 level and temperature targets; validate the tool with actual tests on your lines; rotate lids and ensure fresh components; maintain tight control of fill heights to manage headspace; implement robust CO2 measurement practices and instrument calibration; and set realistic client expectations when approaching the edge of the safe zone to avoid costly failures.

Episode 240: Understanding the Risk of Can Pressure Failures (Feb 2022)

Q: Okay, you can't just make a reference chart without validating the numbers. What safety considerations and methods did you use during the experiments?

We used a temperature-controlled water bath to simulate tunnel pasteurization, while monitoring both the water bath and the internal can temperature, holding at target temperatures for a defined duration to observe when and how cans failed. We wore safety precautions and evaluated both lid and dome failures, noting that older lids tend to fail earlier due to metal relaxation from aging. We also weighed the cans before testing to correlate fill height with performance, and we emphasized repeatability by taking multiple measurements to confirm numerical consistency.

Episode 240: Understanding the Risk of Can Pressure Failures (Feb 2022)

Q: You wrote that there were some surprising results. Take us through each of the can types you tested and how the results shook out.

The standard 12-ounce can showed failures starting in the high 80s to mid-90s PSI across a broad temperature range, with one brand reaching up to about 94 PSI around 146-153 degrees. A Kraft Ale 12-ounce exceeded the design limit more clearly, with failures from roughly 92 to 96 PSI at 153-159 degrees. The Sleek 12-ounce (Seltzer) showed similar variability, with several tests failing above 90 PSI but some failing under 90, depending on the batch and CO2 level, all within a tight temperature window. Overall, cans can survive higher than 90 PSI in some cases, but reliability depends on lot-specific factors like fill height, given headspace and CO2 volume play major roles.

Episode 240: Understanding the Risk of Can Pressure Failures

Q: You wrote that there were some surprising results. Take us through each of the can types you tested and how the results shook out.

The 12-ounce standard cans showed an unexpected 8-degree range of failures with temperatures around 146–153 degrees, the Kraft Ale can failed at higher temperatures, and the Sleek 12-ounce cans had similar variability, with several failures occurring below 90 PSI yet still above the design limits in some cases, emphasizing the variability across brands and lots.

Episode 365: A Western Approach to Sake Production

Q: What was the observed timeline difference between this Western approach and traditional sake production?

The Western approach achieved a roughly seven-day production timeline, compared with the traditional 20–40 days.
