Picture the scene: it’s Friday night, you want to kick back with a nice chilled glass of Chardonnay (or fruit juice, for you teetotallers), but you forgot to put the bottle in the fridge to cool. Doh! But you have the solution: grape cubes!
To chill your drink instantly, without watering it down to a tasteless mess with ice cubes, freeze some grapes and drop them into your glass. When they eventually thaw, they won’t melt and water down your precious, precious alcohol.
