Delicious, I used a homemade ginger liqueur which I deliberately made extra gingery and it pairs wonderfully with the basil on the front, with the freshness of the lime making sure it’s not too much. I would probably drop the simple syrup to 5ml as it was a touch on the sweet side, but I might’ve had particularly sweet grapes.
We did this with Watermelon Vodka, thinking that it might complement the grapes and add even more of a summer vibe. Very nice for us. Substitute a splash of bubbly for the soda if you want to go a bit posh.
The grape, ginger, basil and lime flavours marry extremely well and are very refreshing and original. I reduced the sugar syrup by one third to make a less sweet version as I enjoy an edge of tartness. Increase all the base quantities proportionately and pour into a long glass with ice and lots of soda water - this makes for a superb and distinctive outdoor summer cooler!
