Mataro is the old California name for the grape now more often labeled Mourvedre or Monastrell, the same variety most growers here called Mataro for generations before more recent bottlings adopted the French name. The state's own record traces that transition: acreage under the Mataro name grew from 470 bearing acres in 2000 to 1,069 acres by 2016, spanning 33 counties, and then the name disappears from CDFA's reports the following year as Mourvedre acreage begins being tracked separately. It has long been used both as a standalone red and as a blending partner in Rhone-style GSM wines.

What is published
Counts describe what this atlas holds for Mataro, not what California grows. A zero is a published answer: it means the source names the grape and reports nothing under it, or does not name it at all.

4 wines from 1 producer, each read from that producer’s own tech sheet and linked to it. No average is shown, and none should be computed from these. Wineries that publish tech sheets are selected by their own marketing departments, so a mean across them describes publishing habits rather than a grape.
