Description The first time we saw this funky little label it was showcasing a plush, aromatic Malbec. It’s back, and there’ll be plenty who will welcome it fondly! The name? Somewhat academic but a Mach number is defined as the ratio of two speeds. An aircraft travelling at Mach 2 is going twice the speed of sound, which itself is affected by composition and temperature. Dig a little deeper and you'll come across terms such as 'compressible flow' ... and if you're someone who is more interested in the social side of wine enjoyment rather than the science behind it, you'll probably be wanting to stop reading and pour yourself a glass of this very delicious Malbec showing swathes of fruit to coat your tastebuds.
