I believe there is no time or season limitation for a refreshing cocktail and one of my favorite flavour combination for a refreshing one that I enjoy any time of the year is definitely elderflower and cucumber. When combined with gin, these two makes a great cocktail which would hardly go wrong. The sweet and floral elderflower liqueur compliments the botanical characteristics of gin and cucumber makes the final touch for refreshment. Taking it one step further, adding peppermint foam makes it more refreshing and add more complexity to your drinking experience.
