When it comes to wine most of us don't have a clue where to start. We've all been in the off license picking a bottle based on it either being white or red or simply looking at the price. Things get even more complicated when you hit a restaurant where the wine list can be a serious minefield. A new app from Ex Facebook engineers looks like it could be the answer we have all been looking for. Although there are tons of wine scanning apps they usually rely on scanning the label or barcode but this app lets you scan the menu itself and gives you a full break down on quality, user reviews and what the bottle should ideally cost. It is called Wineglass and it feels like the sort of app that every diner in the world could soon have in their pockets.
