University Of Manchester scientists have used a graphene water filter to turn whisky clear.

The research team at the National Graphene Institute and School of Chemical Engineering and Analytical Science tailored the membrane to allow all solvents to pass through an atomic-scale graphene filter but without compromising its ability to sieve out the smallest of particles.

In typical Mancunian fashion, they filtered whisky and cognac through the graphene-oxide membrane, “just for a fun", which allowed the alcohol to pass through but removed the larger molecules which give the spirits their amber colour.

Apparently, the clear whisky smelt similar to the original whisky but, sadly, the scientists were not allowed to drink it in the lab. This being Manchester, we wouldn't be surprised to learn the results are actually known to a select few who had one hell of a lab party.
