A: Please screw the Lok on tightly. We’ve designed it to allow you to do this without it jumping the thread on the bottle. If someone does somehow manage to get it off and you want to know who it is, either search immediately for someone covered in exploded milk spatter, or leave it until later and see which of your colleagues smells like yoghurt.

Been invited to a party and not sure what to take? Pop a nice red into this brilliant, gizmo and turn it into the talking point of the evening. The complexion of fellow guests may well end up matching the colour of the contents of the bottle as they struggle to fathom out how to free the darn thing whilst it gives you plenty of time to sample the wines brought by others!
