This is the closest winery from Kyoto although it takes 1 h by train and bus.
They offer shuttle bus service from Sonobe station of JR on request.
They run frequent winery tour for free, although the language is almost in Japanese. But you can see from their vineyard to vinification facility.
Surprisingly, they grow more than 40 grape varieties! If you visit them in the end of August, you can see various types of grapes. If you would like to see them, pre-request is strongly recommended.
Some of their vines are more than 35years old with thick trunk as above photo.
They have nice restaurant and celler door, too. So you can enjoy shopping along with tasting.
