In this guide, we'll break down everything you need to know about soda expiration dates, how long soda actually lasts, and the best way to store soda to preserve its carbonation and flavor. Plus, we'll highlight a few fan-favorite options from Poppi that are perfect for your pantry.
Decoding Soda Expiration Dates: What Do Those Codes Mean?
Most soda cans and bottles feature a printed code — often a combination of letters and numbers — that indicates the best-by or expiration date. Unlike perishable foods, soda doesn't typically spoil in a way that makes you sick, but it does lose quality over time. The date is usually a 'best by' date, meaning the manufacturer guarantees optimal flavor and carbonation up to that point.
Common formats include MMDDYY (month, day, year) or a Julian date (e.g., 23524, where 235 is the day of the year and 24 is the year). Some brands also include a time stamp or plant code. If you see 'BEST BY' followed by a date, that's your target. For example, a code like 'APR2525' means April 25, 2025. After this date, the soda may still be safe to drink but could taste less vibrant.
- Look for 'BEST BY' or 'EXP' on the bottom of cans or the neck of bottles.
- Julian dates: first three digits = day of year (001-365), next two = year.
- Soda stored properly can still be enjoyable 3-6 months past the printed date.
How Long Does Soda Last? A Practical Timeline
The shelf life of soda depends on the type, packaging, and storage conditions. Generally, canned soda lasts 9-12 months past the production date, while plastic bottles have a shorter life of about 3-6 months due to slight gas permeability. Glass bottles fall somewhere in between, often retaining carbonation longer than plastic but not as long as cans.
Diet sodas and those with natural sweeteners may degrade faster because artificial sweeteners break down over time, leading to off-flavors. For example, a classic cola might taste fine a year past its date, while a diet version could develop a chemical taste sooner. If you're curious about specific flavors, Poppi offers a range like Ginger Lime and orange-cream-92919">Orange Cream that are beloved for their crisp profiles — best enjoyed before their best-by date.
- Canned soda: 9-12 months from production date.
- Plastic bottles: 3-6 months from production date.
- Glass bottles: 6-9 months from production date.
- Diet sodas: consume within 3 months of best-by date for best taste.
Best Way to Store Soda for Maximum Freshness
Temperature is the most critical factor. Store soda in a cool, dark place between 50-70°F (10-21°C). Avoid temperature fluctuations — don't keep it near the stove, dishwasher, or in a garage that gets hot. Heat accelerates the breakdown of sweeteners and carbonation, leading to a flat, syrupy drink. Humidity isn't a major issue for cans, but it can rust them over time, so a dry pantry is ideal.
Light exposure is another enemy. UV rays can react with the beverage, causing flavor changes and even discoloration. That's why many sodas come in opaque cans or dark bottles. If you store bottles, keep them away from windows. Also, always store soda upright to minimize the surface area exposed to air inside the container, which slows carbonation loss. For a special treat, try chilling a Cream Soda before serving — the cold temperature enhances its vanilla notes.
- Keep soda in a cool, dark pantry (50-70°F).
- Avoid storing near heat sources or in direct sunlight.
- Store upright to preserve carbonation longer.
- Refrigerate only when you plan to drink within a few weeks.
Can You Drink Soda After the Expiration Date?
Yes, in most cases. Soda is a shelf-stable product due to its acidity and carbonation, which inhibit bacterial growth. The main risk is quality loss: flatness, off-flavors, or a change in color. If the can is bulging, leaking, or rusted, discard it immediately — that could indicate a seal failure or contamination.
For the best experience, try to consume soda within 3-6 months of the best-by date. If you're unsure, give it a test sip. If it tastes metallic, overly sweet, or just 'off,' it's time to toss it. Poppi's Classics variety pack is a great way to rotate through different flavors and ensure you always have fresh options on hand.
- Soda is safe to drink months past the date if the seal is intact.
- Check for bulging cans, rust, or leaks before consuming.
- Test a small sip — if flavor is off, discard the rest.
