A very nice, light, slightly sweet spritz - starts with distinct flavors of elderflower liqueur (but not overly strong or sweet), then a hint of cranberry in transition to modest botanicals of the gin. A very refreshing spritz that doesn't present as too sweet or too strong. Very enjoyable - this should be a revisited often as a light and delicious refresher! I note I used sweetened cranberry juice, and didn't find it too sweet at all.

As with other commenters here, we went with unsweetened cranberry juice. We start with a pure juice, with absolutely no additives, and dilute this with chilled water at a ratio of 1:2. We also reduce the tonic water to 60ml. And serve it in a Rocks Glass. A delicious, refreshing and pretty drink.

Post Script- just checked and I used unsweetened cranberry juice- and this suited my partner and I perfectly- there is enough sweetness with the St. Germain Elderflower and Fever Tree Premium tonic. Would I use sweetened cranberry next time? No. This is perfect.

Perfection for a light refreshing cocktail- nothing needs changing for this masterpiece. Caveat and apologies though- no open bottle of Bombay Sapphire in the house so used the Australian gin Never Never Distilling Co. Triple Juniper gin 43% ABV. Will be made frequently in our house.
