The working education begins
At 19, John joined Knipschild Dehydration. He learned the trades in the field and eventually supervised a 63-person operation.

The history behind the promise
NuTrend’s future is credible because it grows from decades of completed work. This history is not decoration—it is the evidence behind the way John sees a system.
At 19, John joined Knipschild Dehydration. He learned the trades in the field and eventually supervised a 63-person operation.
John and Fred Knipschild built equipment and infrastructure for wineries, hospitals, churches, and industrial facilities across Northern California.
John developed the Very Large Machine—known as the Riddler or VLM—to automate the gradual turning and tilting of sparkling-wine bottles.
Lakeport fabrication expanded into specialized retorts, public works equipment, packaging, food processing, fiberglass systems, and custom construction.
John and the NuTrend Team are applying the same whole-system thinking to biomass, filtration, wildfire resilience, circular manufacturing, and the difficult problems clients bring next.
The article that documented the work
In September 1976, a national construction magazine introduced John K. Kalua to its readers as an inventor, engineer, metal fabricator, contractor, and problem solver. The history that follows explains how that recognition was earned—and why John is still working today.
The national magazine profiled John at 39 as the Associated Builders and Contractors’ 10,000th member and presented K&K Metal Construction as a fast-growing St. Helena company serving Napa Valley’s wine country.
“If I know the problem, I can solve it.”
In John H. Wright’s oral history, Wright recalls that Domaine Chandon production leader Gino Zepponi took a large-scale riddling concept to John K. Kalua. Wright describes John as especially capable of reducing ideas to practice and credits him with the practical design of the Very Large Machine.
The system increased capacity from roughly 400 bottles to approximately 4,000 while still using two motors. Wright said the large machine worked better than the smaller machines in some respects—an institutional account of John’s role in scaling sparkling-wine automation.
The transcript misspells John’s surname as “Kahlua.” John’s reference appears on PDF page 105 in the supplied archival copy.
