I got a large bottle of the original aperitif to have around as something that still feels festive and fun (and not just like an afterthought) for when we have people over and someone doesn't feel like drinking for whatever reason. Since then, my spouse and I have both tried it with just a little sparkling water, and we both liked it! We haven't really tried to get more elaborate with cocktails, but I would imagine adding some kind of sweet component would make it even tastier (there's really no sweetness to the product by itself). Also, I know it might seem silly, but I actually think that the design/ branding of the bottle itself, and the beautiful color of the liquid inside, make a difference in terms of our reason for trying Ghia (having inclusive drink options around when we entertain).
I don't think the claims about "energy" and "calming the mind" should be the reason you try this. I'm not sure those effects really exist. Which is fine! It's a fun and fancy nonalcoholic drink option, and it doesn't have to have health benefits!
