I've posted a few times about this. None of the boxed 'wines' here is purely grape wine. Many of the bottles too. They might or might not have some portion of grape juice or grape wine, or they could be fruit juices mixed with straight alcohol. The labelling rarely gives any useful information. It is misleading, not to say deceitful. That is why I started to make my own, at least I know what is in it.
This doesn't stop me from having a glass or three of Mont Clair when I am outside.
Try adding some ice and soda water and pretending it is a wine spritzer.
You can get adventurous and also add a splash of lemonade and a slice of orange. If that is not sufficiently manly then further add a splash of Regency and a slice of Thai lemon and tell yourself it is a Sangria. Best make a jug of the stuff to save time.
