Put together this list from vineyard visits and from winemaker info, gathered from write-ups on my various travels and tastings for Grape-Nutz.com since 2006. These are mostly blocks of own-rooted vines within vineyards rather than entire vineyards. But based on this being a list from one person’s visits through scattered growing areas up and down the state - and just happening upon these examples - there must be many more blocks and entire vineyards in California that have own-rooted vines. I also included one Oregon vineyard that I happened to see listed in my noteswith own-rooted vines.
