Good mocktail for a lady into moscato & soda like sprite?

Seems like the consensus is non alcoholic wine is a meh compared to a mocktail. Any ideas for a lemon lime style mocktail? This is for a beach picnic date, trying to elevate it vs just bringing tea and sprite. I’m a complete amateur so preferably something easy to make, especially since it’s on the beach with stuff in a back pack. Thanks!
