Fruit – Whatever kind you like (except bananas); make sure it’s good and ripe for maximum sweetness and flavor. Use all kinds of citrus and berries. Pineapple and watermelon work well for flavoring water.
Herbs – These are optional, but many herbs are a surprising complement to fruit flavors; almost any herb will work depending on your personal preference
Jars or pitchers – Use 2 quart mason jars primarily, but any 2 quart pitcher will do. Fruit infusion pitcher is another option if you think you’ll be making infused waters regulary; a very easy, tidy way to strain fruit from water.
Muddler or wooden spoon for mashing fruit and herbs
Water – Use filtered water, but regular tap water is fine if it is hygienic.
