To my knowledge you cant advertise on airbnb, what you can do
Make a guide book for your wine tours
Also thats what airbnb's "Experience" is all about but you are not guaranteed to be accepted as in my case I was declined twice, I dont know the reason why,
The other thing that put me off was the 20% commission airbnb charge, Their loss.
You could add some photo's without the links,
Print off the guide book to leave in your listing,
Big question here do you get commission from the wineries? if not why not
Once the guest has booked you can send them a message about your tours I used to tell my guest not to book anything online we have all the contacts and local knowledge here,
