Your wedding day is a time for expressing the love and commitment you have for your partner in front of all your friends and family. It is a time of celebration and togetherness with friend and family who will inevitably, as has been done for centuries, toast the nuptials.
You will surely struggle to recall a wedding you have attended where a glass was not raised to the happy couple at some stage, if not multiple stages, during the celebrations. There was probably wine accompanying your meal, and champagne passed around for speeches; maybe there was even an open bar. Wine, in particular, has featured heavily in celebrations across the world, and holds a deeper symbolic resonance within some religions, in some cases being a feature of the wedding service itself.
