SToK produces two distinct types of ready-to-drink coffee products that users often confuse: single-serving espresso shots and larger refrigerated cold brew bottles. Understanding the difference is key to knowing their respective shelf lives, as they are prepared and packaged differently. The single-shot containers are aseptically packaged, allowing for a long, shelf-stable life, while the multi-serve cold brew requires continuous refrigeration.
Shelf Life for Unopened SToK Espresso Shots
The most important detail regarding SToK espresso shots is their long shelf life prior to opening. These are not refrigerated items at the point of sale. Instead, they are sealed using aseptic packaging, a process that extends their longevity significantly. According to specifications from a product vendor, these single-serving shots have a shelf life of approximately 130 days from the date of manufacture and do not require refrigeration until opened. This makes them an ideal portable and long-lasting energy boost.
Key aspects of unopened storage:
- Location: Store the shots in a cool, dark place, away from direct sunlight and heat.
- Expiration Date: Always check the 'Best By' date printed on the packaging to ensure the best possible quality.
- Packaging Integrity: The longevity relies on the sealed packaging. Do not use if the box or individual container appears damaged.
What Happens After Opening a Single Shot
Unlike the larger bottles, the individual SToK espresso shots are designed for immediate, single-use consumption. Once the seal is broken and the coffee is exposed to air, the quality begins to degrade rapidly. This is similar to a freshly pulled espresso shot from a coffee shop, which loses its complex flavor and crema within minutes. Therefore, for the best taste and experience, the contents of a single shot should be consumed in one sitting.
Comparing SToK Espresso Shots and Refrigerated Cold Brew
Confusion often arises because SToK also sells larger, multi-serving bottles of cold brew coffee that are kept refrigerated in stores. The shelf life for these products is considerably different and depends on whether the bottle is opened or not. Below is a comparison to clarify the differences.
| Feature | SToK Espresso Shots | SToK Refrigerated Cold Brew Bottles |
|---|---|---|
| Packaging | Individual, aseptic containers | Larger, resealable bottles |
| Storage (Unopened) | Shelf-stable; no refrigeration needed | Must be kept refrigerated |
| Unopened Shelf Life | Approximately 130 days from production | Varies, but can be 4–6 months refrigerated |
| Opened Shelf Life | Immediate consumption recommended | 7–14 days in the refrigerator |
| Volume | Single-serving | Multi-serving |
| Purpose | Quick caffeine boost, travel-friendly | Daily iced coffee at home |
How to Tell if Your SToK is Bad
Whether you're using a single shot or a large bottle, it's always important to check for signs of spoilage before consuming. Relying on your senses is the best method.
- Smell: A fresh SToK product should have a pleasant coffee aroma. If it smells sour, rancid, or fermented, it's past its prime and should be discarded.
- Appearance: Look for unusual cloudiness, mold growth, or excessive separation. Some natural sediment is normal in cold brew, but any fuzzy mold or slimy texture is a clear sign of spoilage.
- Taste: The flavor is the ultimate indicator. A bitter, sour, or metallic taste means the coffee has gone bad.
- Bloated Packaging: For the single shots, if the aseptic container or box appears bloated, it could indicate microbial activity and should not be consumed.
Proper Storage to Maximize Freshness
To ensure you get the most out of your SToK coffee, follow these storage best practices:
- Single Shots: Store the unopened containers in a cool, dark pantry. Once opened, use the entire shot at once.
- Refrigerated Bottles: Always keep the bottle in the refrigerator, both before and after opening.
- Minimize Air Exposure: For large bottles, minimize the time the cap is off and ensure it's sealed tightly after each use to slow oxidation, which dulls the flavor.
- Keep Away from Odors: Coffee is absorbent. Store the bottles away from strong-smelling items like onions or garlic in the fridge.
Conclusion
The shelf life for SToK espresso shots is quite long—around 130 days unopened—due to their special aseptic packaging, which means they are shelf-stable and don't require refrigeration. In contrast, SToK's larger refrigerated cold brew bottles last for 7–14 days after opening. The key difference lies in the packaging and intended use: single shots for immediate consumption versus resealable bottles for multiple servings. By understanding these distinctions and following proper storage methods, you can ensure each sip of SToK coffee is as fresh and flavorful as intended.

A list of simple ways to maximize SToK coffee freshness
- Refrigerate After Opening: Always return the multi-serve cold brew bottle to the fridge immediately after pouring.
- Tightly Seal Containers: Ensure the caps on both single shots and larger bottles are securely closed.
- Respect the 'Best By' Date: Pay attention to the manufacturer's suggested date for optimal quality.
- Consume Single Shots Promptly: Finish the entire espresso shot immediately after opening for the best taste.
- Keep Away from Light and Heat: Store all coffee products in a cool, dark location to prevent degradation.
- Monitor for Spoilage: Regularly check for off smells, sour tastes, or unusual appearances before drinking.
- Store in Glass if Transferring: If for any reason you transfer cold brew, use a clean, airtight glass container to prevent flavor absorption.
- Avoid Mixing Additives: For large bottles, only add milk, cream, or sweeteners to your individual serving, not the entire container, to prolong its fridge life.
Conclusion
The shelf life of SToK products varies significantly depending on the specific item and its packaging. The single-serving espresso shots are shelf-stable for about 130 days unopened due to aseptic packaging, but should be consumed immediately after opening. The larger, multi-serve cold brew bottles require continuous refrigeration and should be used within 7-14 days of being opened. Following proper storage techniques—like minimizing air exposure, keeping products chilled after opening, and using fresh ingredients—is crucial for maintaining both flavor and safety. When in doubt, trust your senses and check for signs of spoilage like off-flavors, odors, or visible mold to ensure an optimal and safe coffee experience.
Frequently Asked Questions (FAQs)
Can I drink a SToK espresso shot if it has been opened for a few hours?
No, for the best taste, an opened SToK espresso shot should be consumed immediately. The flavor quality degrades very quickly upon exposure to air, just like a freshly pulled espresso from a machine.
How long does a refrigerated SToK cold brew bottle last once opened?
Once opened, a refrigerated SToK cold brew bottle is best consumed within 7 to 14 days. Ensure you keep the cap tightly sealed and return it to the refrigerator promptly after use to maximize its freshness.
Is it safe to drink SToK coffee past its 'Best By' date?
For unopened products, a 'Best By' date typically refers to peak quality, not food safety. However, if the product is past this date, the flavor may be stale. For opened bottles, especially those past their recommended consumption window, you should check for signs of spoilage before drinking.
Do I need to refrigerate unopened SToK espresso shots?
No, the SToK espresso shots come in aseptic, shelf-stable packaging and do not require refrigeration as long as they remain unopened. You only need to chill them if you prefer to drink them cold.
What are the main signs that SToK cold brew has gone bad?
Signs of spoilage include a sour or unpleasant smell, a bitter or metallic taste, and visible mold or excessive cloudiness. If the packaging of an unopened item is bloated, discard it immediately.
Why do SToK espresso shots and cold brew bottles have different shelf lives?
The difference is due to their packaging and processing. Espresso shots use aseptic packaging for a long, shelf-stable life, while the larger cold brew bottles rely on refrigeration to maintain freshness after opening.
Does adding milk to SToK cold brew affect its freshness?
Yes, adding milk, cream, or other additives to your SToK cold brew will significantly shorten its shelf life, reducing it to a few days even when refrigerated. To prevent this, always add milk and sweeteners to individual servings rather than to the entire bottle.
