These glasses from Fab are a great idea if you’re low on cupboard space, or if you just hate washing multiple glasses at the end of a night. The glass has been designed so that you can fill the smaller end with wine (or the larger end, depending on your alcohol dependency), then when you’ve finished, just flip the glass over and fill the deeper end with water. The design is theoretically great, and the design is quite attractive. Overcome problems with hygiene (where has the rim of the bottom glass been?) and the likelihood of dripping wine, and you’re on to a winner!
