Can I drive safely after a lesson?

The courses offered by WineWise are professional courses. We insist that you spit out all the wines. Each participant has their own spittoon for this. Research has shown that if you spit out all the wines, the amount of alcohol you ingest is negligible. If we notice that you do not comply with this, the teacher has the right to point this out and, if necessary, to refuse you access to the next lesson.
