Understanding the 'Best By' Date
Unlike a strict 'use-by' date for perishable foods, the 'best by' date on Built protein bars and similar products refers to quality, not safety. It is the manufacturer's estimate of how long the product will remain at its peak in terms of taste, texture, and nutritional value. Past this date, the bar may become harder, lose some flavor, or experience changes in texture, but it is generally still safe to eat if stored correctly and shows no signs of spoilage.
Factors Affecting Built Bar Shelf Life
Several elements contribute to a Built Bar's longevity. Understanding these can help you better preserve your snacks.
- Ingredients: The specific components of the bar play a huge role. For example, bars with higher fat content are more susceptible to oxidation, which can lead to rancidity over time. Built Bars, which often contain dairy-based protein and gelatin, have different preservation needs than vegan bars.
- Packaging: The packaging is a critical barrier against oxygen and moisture, which are primary drivers of degradation. Built's individual bar wrappers are designed to be airtight, but any punctures or damage can compromise the seal and shorten shelf life.
- Storage Conditions: Temperature and humidity are major factors. Elevated temperatures accelerate the chemical reactions that cause a bar to harden and lose flavor. For optimal results, Built Bars should be stored in a cool, dry place.
What to Look For to Tell if a Built Bar is Bad
Even before the 'best by' date, a bar can spoil if not stored correctly. Look for these signs before eating:
- Visual Inspection: Check for signs of mold, which may appear as dusty or discolored spots. Also, look for "chocolate bloom," a harmless whitish or gray film caused by temperature fluctuations that affects texture but not safety.
- Odor Test: A bar that smells rancid, sour, or otherwise "off" is likely spoiled. The fats and proteins can go bad over time, creating an unpleasant aroma.
- Texture and Taste: A fresh Built Bar is known for its soft, chewy texture. If the bar is excessively hard, dry, or has a stale taste, its quality has diminished. If the taste is bitter or unpleasant, discard it.
Comparison: Proper Storage vs. Poor Storage
To illustrate the importance of storage, here is a comparison of how Built Bars behave under ideal versus poor conditions.
| Feature | Optimal Storage (Cool, Dry Place) | Poor Storage (Hot, Humid Environment) |
|---|---|---|
| Shelf Life | Retains peak flavor and texture for up to 6-12+ months. | Quality deteriorates much faster, often within weeks or months. |
| Flavor | Stays true to the original flavor profile, without off-notes. | Flavors can become stale, muted, or develop a rancid taste. |
| Texture | Maintains the signature soft and chewy consistency. | Hardens and becomes dry, often losing its pleasant chewiness. |
| Nutritional Value | Guaranteed to meet label claims until the 'best by' date. | The protein and nutrient potency can degrade over time. |
| Safety | Very low risk of microbial growth or spoilage. | Increased risk of spoilage, especially if moisture is introduced. |
How to Maximize Your Built Bar's Shelf Life
To ensure your Built Bars last as long as possible, follow these simple storage tips:
- Find a Cool, Dry Spot: The pantry or a kitchen cabinet away from the stove is ideal. Avoid storing them in direct sunlight, in your car, or near heat sources.
- Consider Refrigeration: While not strictly necessary, refrigerating your bars, especially in hot weather, can help preserve their texture and prevent melting.
- Keep Sealed: Do not open a bar until you are ready to eat it. The individual, airtight wrapper protects it from oxidation and moisture.
- Monitor Best By Dates: Regularly check the dates on your inventory and prioritize eating the older bars first. This is a simple way to practice good stock rotation.
Conclusion
While Built protein bars are formulated for a relatively long shelf life, typically indicated by a 'best by' date 6 to 12 months from production, their actual longevity and quality are heavily influenced by storage conditions. Proper storage in a cool, dry place is crucial for preserving their unique flavor and soft texture. By paying attention to the best by date and checking for common spoilage signs, consumers can safely and enjoyably consume their Built Bars, even slightly past their peak.

The Final Word
The shelf life of a Built Bar is more about maintaining quality than a safety cut-off. Adhering to proper storage practices will ensure you get the best experience from every bite, well within the manufacturer's suggested timeframe. When in doubt, a quick visual and odor check is your best tool for determining if a bar is still good to go.
