Mountain Dome is another one of my top fave wineries in the Spokane area. This one is in the valley so it’s a bit of a drive from downtown but well worth a visit. It’s located in an out-of-the-way spot and they only open on Saturdays and special occasions as far as I know (check their website).
I normally don’t go for Sparkling Wines or Champagne however, this is what these guys make and they do it right! They even turn the bottles by hand which is how Champagne used to be made in France.
