How to Store Hiyo Seltzers So They Stay Fresh and Fizzy

Quick answer

Store unopened Hiyo cans upright in a cool, dark place like a pantry or cabinet, away from heat and direct sunlight. For the best drinking experience, chill them in the fridge for at least 2–3 hours before serving. Once opened, reseal the can if possible or transfer to a glass and drink within a few hours to preserve carbonation.

Why storage conditions matter for carbonated seltzers

Carbonation is sensitive to temperature and movement. Warmth causes the dissolved carbon dioxide to expand and escape more quickly, while heat and light can degrade delicate flavors over time. Hiyo social tonics are crafted with adaptogens, nootropics, and botanicals, and these functional ingredients are best preserved when cans are kept in stable, cool conditions. Unlike some beverages, Hiyo does not require refrigeration for safety before opening, but chilling improves both taste and fizz retention.

How to store unopened Hiyo cans

The ideal spot for unopened Hiyo is a cool, dark cupboard or pantry where the temperature stays consistent—ideally between 60°F and 75°F (15°C–24°C). Avoid storing cans above the fridge, near the stove, or in a garage that swings between hot and cold. Keep them upright to minimize the surface area where carbon dioxide can escape through the can's lining. If you buy in bulk, rotate your stock so older cans are enjoyed first. The classic pack, for example, includes four flavors, so you can store them together and grab whichever suits your mood without disturbing the rest.

The best way to chill Hiyo drinks

For a quick chill, place cans in the fridge for at least 2–3 hours. If you need them faster, a bowl of ice water with a handful of salt can bring them down in about 15 minutes—but avoid the freezer, as freezing can distort the can and dull the carbonation. Once chilled, keep them in the fridge until you're ready to drink. The blackberry lemon flavor, with its bold blackberry and zesty lemon notes, tastes especially refreshing when served well-chilled.

What to do with leftover or opened cans

Hiyo cans are best enjoyed in one sitting, but if you have some left, pour it into a glass and cover it with a saucer or plastic wrap to slow carbonation loss. Drink within a few hours. You can also use flat Hiyo as a mixer in mocktails or salad dressings—don't pour it down the drain. If you opened a can and didn't finish it, don't put it back in the fridge for days; the flavor and fizz will be noticeably diminished.

Step-by-step storage routine

1. Check the date and rotate: Before storing, check the best-by date on the bottom of each can. Arrange older cans in front so you drink them first. A simple rotation prevents forgotten cans from going flat over time.
2. Choose a cool, dark spot: Find a pantry shelf or cabinet that stays between 60°F and 75°F and is out of direct sunlight. Avoid areas near heat sources like the oven or a sunny windowsill.
3. Keep cans upright: Store Hiyo cans standing up, not on their sides, to reduce the area where carbonation can escape. Upright storage also makes it easier to read labels and grab your favorite flavor.
4. Chill only what you plan to drink soon: Move cans to the fridge 2–3 hours before serving. You can chill the whole pack if you have space, but repeated warming and cooling can affect taste. For impromptu gatherings, use an ice bath instead of the freezer.
5. Handle opened cans promptly: If you can't finish a can, pour it into a glass, cover it, and refrigerate. Drink within a few hours. Never leave an open can at room temperature for long—it will go flat quickly.
