Does it cost to go into the winery

No.

There is not an admission to the winery, tasting is about $20, a lot of times they are on Groupon too if you want to save some money.

I'm not sure. I went on a wine tour for the day. It included Lorimar as one of the winery's. 8 people went and cost us $80.00 per person. Lots of fun.

Only if you want to taste the wine
