Blueberry Cucumber Rosemary Water: Easy Recipe

Blueberry cucumber rosemary water is a chilled fruit-and-herb infusion that takes 2 hours 10 minutes to make and yields about 1 liter (4¼ cups), or 4 servings.

What is blueberry cucumber rosemary water?

Blueberry cucumber rosemary water is plain water infused with blueberries, sliced cucumber and fresh rosemary. The berries add a subtle fruity note, the cucumber keeps the flavor light, and the rosemary adds an herbal aroma.

It is one of many berry infused water recipes you can make without added sugar. Because the ingredients are steeped rather than blended, expect a gently flavored drink, not a sweet juice.

What ingredients and ratio do you need?

For about 1 liter (4¼ cups), use:

Water: 1,000 ml (about 4¼ cups)
Blueberries: 150 g (about 1 cup)
Cucumber: 150 g (about 1½ cups sliced)
Fresh rosemary: about 5 g (2 sprigs, or roughly 2 tablespoons of loosely packed leaves)

The measurements do not have to be exact. Keep the rosemary on its sprigs for easy removal, and use the cup measure as an approximate guide because sprig sizes vary.

This ratio gives the berries and cucumber room to flavor the water without making the rosemary too prominent. Use a pitcher large enough to hold both the water and the ingredients comfortably.

How do you make blueberry cucumber rosemary water?

Allow 10 minutes for preparation and at least 2 hours for refrigerated steeping.

Wash the blueberries, cucumber and rosemary under cool running water. Use a clean pitcher and clean utensils.
Slice the cucumber into thin rounds. Leave the blueberries whole, or gently press a few with a spoon for a fruitier flavor.
Add the blueberries, cucumber and rosemary sprigs to the pitcher, then pour in the water.
Cover the pitcher and refrigerate for 2–4 hours. Taste after 2 hours and remove the rosemary or strain the water when the flavor suits you.

Serve the water chilled, with or without the fruit and cucumber in the glass. If you prefer a lighter herbal taste, remove the rosemary first and leave the other ingredients in while the pitcher remains refrigerated.

Why do blueberries, cucumber and rosemary pair well?

Blueberries bring mild fruitiness without making the water taste like juice. As with blueberry infused water, gently pressing a few berries can release more flavor, although the drink will still be much less concentrated than a smoothie.

Cucumber contributes a fresh, mild taste that leaves room for the berries and herbs. It gives this recipe the same crisp character people look for in cucumber water, without needing a sweetener.

Rosemary adds a fragrant, savory edge. A little goes a long way, so taste the pitcher before adding more; for a more herb-forward drink, see rosemary water.

The main benefit of this infusion is hydration. Blueberries and cucumber contain nutrients when eaten, but the amount that transfers into steeped water is uncertain. The liver and kidneys do most of the body's detoxification; this drink supports hydration rather than flushing out toxins.

How should you store blueberry cucumber rosemary water?

Keep the pitcher covered and refrigerated, including while it steeps. Drink the water within 24 hours for the best flavor. Discard it after 2–3 days, or sooner if it becomes cloudy or slimy, or smells sour.

Straining out the ingredients once you like the flavor can keep the rosemary from becoming overpowering, but it does not extend the recommended storage time. Refrigerate the strained water promptly rather than leaving it out at room temperature.

If you plan to eat the blueberries or cucumber, keep them refrigerated too. Eating the fruit adds its calories and nutrients; those amounts should not be counted as though they were all present in the steeped water.

How can you vary the recipe?

For a berry-forward version, gently press more of the blueberries before adding the water. The result may be a little cloudier, so strain it before serving if you prefer a clearer drink.

For a subtler infusion, leave the berries whole and remove the rosemary after tasting at 2 hours. Thin cucumber slices expose more surface area than thick pieces; cut them thicker if you want a milder cucumber note.

You can also adjust the balance on your next batch: use a little less rosemary or a few more cucumber slices while keeping the same amount of water. Make one change at a time so it is easy to tell which flavor you prefer.
