It is easy to taste wine in many places during this period. Despite what is being said, there are few controls.
As for UGC, as well as us, it is preferable to ask for invitations to someone you buy your wine from. They will be able to include your name in guests lists. It is clear though that the goal for this tasting is to promote our wines so we can sell them, not to compete with the local wine bar and drink for free. I think you won’t have any problems to get invitations (especially this year!)
