@Heidi873 unless the wine is alcohol free then you are breaking licensing laws by leaving it for guests even if there is no charge - Crazy but thems the rules.
Try JL Morris insurance brokers for insurance. we don't rely on Aircover and it certainly will not cover many situations where say there is a fire/flood between guests and a standard household policy may be invalidated if you do Airbnb.
Finally recent and very stringent fire regulations have just come in for short term rentals. They are a nightmare!
