The high amount of sugar in this cordial makes it sweet and long-lasting. Store unopened bottles in a dark and cool place. Once opened keep your cordial in the fridge.
I sterilise my bottles by filling them up with boiling water. I explain it here.
Drink the cordial diluted with water (still or sparkling), a dry white wine or prosecco. You can add a few mint leaves, some ice and a piece of lime as well!
I really like to use the syrup in a salad dressing as well (combine with mustard, apple vinegar, Provencal herbs and olive oil).
