Q:  Why do your panels cost only slightly more than running a single test?

A:  In the wine lab of yesteryear every parameter had to be run as a separate analysis. Today's sophisticated modern wine analyzers generate a powerful amount of data in a single pass. We choose to treat that data as a single analysis from a billing standpoint.  This hopefully incentivizes you to run more analysis, keep a closer eye on your product, and ensure it stays on track from start to finish.
