Northern Sonoma is a diverse, sprawling part of California's wine country encompassing three major wine-growing regions (and many smaller ones) plus several popular wine country towns including Healdsburg, Guerneville, and Santa Rosa. While some areas don't seem to have changed in years, others can be just as dynamic as Southern Sonoma or Napa Valley, so keep an eye out on these pages for updates and news. And contact me if you find any important changes not covered here.
