Fortnum's Sparkling Tea, 0% ABV, Magnum

A magnum from Fortnum’s is more than simply impressive in size. Due to the relatively smaller volume of air in contact, the wine in a magnum bottle actually ages more gracefully, creating additional complexity of aroma and flavour. When it comes to Champagne and Sparkling wines in particular, magnums also produce finer, more persistent bubbles, and are less affected by temperature changes — so the liquid inside can better retain its integrity and all-important effervescence. Or in other words: if your wine could talk, it would tell you that it's altogether more content in a bigger bottle.
