It’s hard to describe the flavour. It tastes faintly of crisp, fresh berries, mixed with honey and bubbly champagne. There’s also a faint hint of lemon and something else which I can’t describe, except to say it’s not really a taste but more of a sensation. The sensation is . . . exhilaration. Like standing on the front of a speeding boat, or diving off a cliff into the ocean. No words do it justice.
