There are about 35 wineries along the 15 kms between us here in little Naramata and the larger centre of Penticton. All but one are open around 10 am daily during June through to end of September. There are
loads of tour operators with 12 to 15 seat buses. They stop in at four or five wineries in an afternoon and often stop at one for lunch. Getting to be BIG business. When we moved here in 2005 there were 15 wineries so tremendous growth. At first no tasting fees but with so many people touring the fees were necessary. Winery owners do not generally like the tour buses because their patrons usually do not buy.
$25 for a couple of ounces seems a bit much and $5 for multiple tastes seems low. Weird.
