Out of all the recipes I've tried, this is my absolute favorite non-alcoholic recipe from the book Regarding Cocktails! It does contain angostura bitters, but you can leave those out if you want the drink to be 100% alcohol free. But even if you don't, it contains no more than kombucha would. Excellent recipe to make in large batches that you can add soda water to when ready to drink!

Recipe:

• 1 oz. Lemon juice
• 1 oz. Pineapple juice
• 1 oz. Ginger syrup
• 1 Bar spoon of maple syrup
• A dash of angostura bitters
• 3 oz. Soda water

Combine all but the soda water and shake vigorously with ice. Strain into a Collins glass with a spear of ice and a straw. Carefully top with soda water. (There isn't a garnish in the book, but some suggestions I like to use include mint, cucumber, lemon peel, or candied ginger).
