Nagging Doubt keeps things tiny and appointment-only in Kelowna, the owners' two dogs personally greeting every single visitor at this small winery. At 4.9 stars, it's nearly as beloved as a winery gets, thanks in real part to that consistent, personal canine welcome. This is a tasting experience built around genuine intimacy, dogs included. Book an appointment ahead, and expect a warm greeting from two very good dogs. Kelowna's tiny, appointment-only winery with the two-dog welcome committee.
