Learn expert tips to keep your Dalston's real fruit sodas fizzy after opening. From proper sealing to temperature tricks, enjoy every last bubbly sip.
You've just cracked open a can of Dalston's Soda Co's chef-crafted real fruit soda — maybe a bright Lemon or a sweet Pineapple — and you're savoring that perfect, lively fizz. But life gets busy, and you can't always finish the whole can in one sitting. The last thing you want is to come back to a flat, lifeless drink that's lost its charm.

Fortunately, with a few simple techniques, you can keep your Dalston's soda carbonated longer after opening. Whether you're nursing a can over an afternoon or saving half for later, these practical tips will help preserve that artisan fizz and fresh fruit flavor. Let's dive into the science and the hacks.
Why Sodas Go Flat After Opening
Carbonation is the result of carbon dioxide gas dissolved under pressure into the liquid. When you open a can or bottle, that pressure is released, and CO₂ begins to escape into the air. Over time, the concentration of dissolved gas drops, and the soda loses its fizz. Temperature, surface area, and how tightly you reseal the container all affect how quickly this happens.
For premium sodas like Dalston's — which use real fruit juices and chef-crafted recipes — the carbonation is a key part of the experience. The delicate balance of fruit flavor and effervescence is worth protecting. Understanding the physics behind flat soda is the first step to preventing it.
- CO₂ escapes faster when the liquid is warm — cold temperatures slow down gas diffusion.
- A wider opening exposes more surface area, allowing gas to leave more quickly.
- Shaking or agitating the can accelerates gas loss.
Tip #1: Reseal Immediately and Properly
The simplest and most effective way to keep your Dalston's soda carbonated is to minimize the time it's exposed to air. If you're drinking from a can, pour only what you plan to drink into a glass, then immediately cover the can opening with plastic wrap and a rubber band, or transfer the remaining soda to a bottle with a tight-fitting screw cap. For bottles, always screw the cap back on tightly after each pour.
This reduces the surface area available for gas exchange and keeps the CO₂ inside the liquid. Even if you're saving just a few ounces, a proper seal can make a noticeable difference hours later. Think of it as locking in the freshness that Dalston's chefs intended.
- Use a bottle stopper or a can cover designed for carbonated drinks.
- Avoid leaving the can open on the counter — every second counts.
- For best results, transfer to a smaller container to minimize headspace.
Tip #2: Keep It Cold — Refrigerate After Opening
Temperature is one of the biggest factors in carbonation retention. Cold liquids can hold more dissolved CO₂ than warm ones. Once you've opened a can of Dalston's Lemon or any other flavor, place it back in the refrigerator immediately after resealing. The colder the soda stays, the slower the gas will escape.
Avoid leaving your soda at room temperature for extended periods. If you're enjoying a can over a couple of hours, keep it in a cooler or an insulated cup with ice. This is especially important during summer months when ambient temperatures are higher. Your taste buds will thank you for that crisp, fizzy finish.
- Refrigerate within 30 minutes of opening for best results.
- Use a thermos or insulated bottle to maintain cold temperature on the go.
- Never store opened soda near a heat source or in direct sunlight.
Tip #3: Minimize Agitation and Pour Gently
Shaking or vigorously pouring your soda can cause rapid CO₂ release, leading to a flat drink much sooner. When you handle your Dalston's soda, be gentle. Pour it slowly down the side of a glass to preserve the carbonation in the remaining liquid. If you're sharing, pour each serving carefully rather than shaking the can to mix.
This is particularly relevant for sodas with natural fruit pulp, like Dalston's Pineapple or Peach, where you might be tempted to swirl the can to redistribute sediment. Instead, give the can a very gentle tilt before opening, or stir the glass with a spoon. Your patience will be rewarded with a longer-lasting fizz.
- Open the can slowly to avoid a sudden pressure release.
- Pour at a 45-degree angle to reduce foam and gas loss.
- Avoid using a straw — it can introduce air bubbles that accelerate flatness.
Tip #4: Use a Soda Preserver or Vacuum Pump
For serious soda enthusiasts, a soda preserver — a device that pumps out excess air and creates a vacuum seal — can extend carbonation for days. These tools are designed for carbonated beverages and work by removing the air above the liquid, which slows CO₂ escape. While Dalston's sodas are best enjoyed fresh, a preserver can be a game-changer if you often find yourself with leftover soda.
Alternatively, you can use a simple wine stopper or a specialized carbonation cap that fits standard bottles. If you've opened a larger bottle of Dalston's Mixed Pack variety, this can help you enjoy different flavors over several days without losing the sparkle. Just remember to refrigerate after each use.
- Look for vacuum sealers designed for soda bottles.
- Some caps allow you to re-pressurize with a CO₂ cartridge — ideal for long-term storage.
- Always clean the device after each use to avoid flavor contamination.
Bonus: Which Dalston's Sodas Hold Carbonation Best?
All Dalston's real fruit sodas are crafted with care, but some flavors naturally retain carbonation better due to their ingredient profiles. Sodas with higher acidity, like Lemon or Rhubarb, tend to hold fizz slightly longer because the acidic environment slows CO₂ dissolution. Meanwhile, sweeter, pulp-heavy flavors like Peach or Cherry may lose carbonation a bit faster if not stored properly.
If you're planning to sip slowly, consider starting with a Lemon or Elderflower, which have a bright, clean finish. For a refreshing mix, the Taster Pack 12 Cans is a great way to experiment with different flavors and see which one you enjoy most over time. No matter your choice, these tips will help you get the most out of every can.
- Acidic flavors like Lemon and Rhubarb tend to stay fizzy longer.
- Pulp-heavy sodas benefit from gentle handling and immediate resealing.
- The Taster Pack is ideal for testing carbonation retention across varieties.
Keeping your Dalston's soda carbonated after opening doesn't require fancy gadgets — just a few mindful habits. Reseal promptly, keep it cold, handle gently, and consider a preserver for extended enjoyment. With these tips, every sip of chef-crafted real fruit soda will stay as lively as the first.
