A blend of wine tasting experiences and vacation

My wife and I went to Australia and tasted wines throughout the Barossa Valley, it was a great winecation.

We went on a winecation to Woodinville and tasted wines in the warehouse district with friends.

Out trip to Italy was the best winecation we have been on.

Drinking until you think you are someplace exotic.
After a week of automobile breakdown, vomiting dogs, and calls from daycare about preschool children who inappropriately touched their classmates, I am ready to go on a winecation this weekend.
