Shelf-Life & Stability
Drink Shelf-Life & Stability Support
Understand how your drink may change over time and build a proportionate plan to assess quality, stability and the conditions needed for its intended shelf life.
Plan for product life
Assessing stability from formulation to finished pack
Shelf-life is a product-specific question involving formulation, processing, packaging, storage conditions and the quality characteristics that matter to consumers.
A drink can look and taste right when freshly made yet develop changes during storage. Depending on the product, these may include flavour fade, colour changes, sediment, separation, carbonation loss, texture changes or microbiological spoilage.
A useful stability plan starts by identifying the product risks and the evidence needed. Testing should use representative product, the intended packaging and clearly defined storage conditions, with suitable analytical or microbiological testing where required. Accelerated studies can inform understanding, but they do not automatically replace real-time shelf-life evidence.
Stability work can be considered alongside recipe development, scale-up and production support so decisions are connected across the product lifecycle.
Technical support
Areas we can work through
Project scope is tailored to the product, its current stage and the decisions that need to be made.
Identify likely failure modes
Review ingredients, acidity, processing, packaging and storage to identify plausible physical, chemical, sensory or microbiological risks.
Define a testing plan
Set out samples, time points, storage conditions, observations and relevant laboratory tests for the product.
Review changes over time
Compare results against product expectations and agreed acceptance criteria.
Investigate issues
Help structure a technical review when a product shows separation, sediment, flavour change or other stability concerns.
Independent support
A practical approach to stability questions
The relevant tests depend on the drink, its process, pack format and intended storage conditions.
Use a defined protocol and documented observations rather than relying on a single fresh sample or informal tasting.
Consider stability alongside formulation choices and manufacturing conditions, not as an isolated final check.
How a project runs
A clear path from review to next steps
Understand the product
Review the recipe, process, packaging, target shelf life and distribution conditions.
Map the risks
Identify likely changes and the product characteristics that need to be monitored.
Agree the study
Set sample plans, storage conditions, time points, assessment methods and any external laboratory requirements.
Interpret and act
Review the evidence and identify whether formulation, process, packaging or further testing needs attention.
Questions
Shelf-Life & Stability FAQs
Can you guarantee a specific shelf life?
Shelf life should not be guaranteed without appropriate product-specific evidence. The work can help define and interpret a suitable assessment plan.
What causes drinks to become unstable?
Potential causes include ingredient interactions, pH, oxygen, heat exposure, light, packaging compatibility, processing and microbial growth. The relevant risks vary by product.
Are accelerated stability tests enough?
Accelerated tests can provide useful early information, but their relationship to real-time storage depends on the product and the change being studied.
Do I need microbiological testing?
That depends on the product, process, packaging, storage conditions and food safety requirements. Appropriate qualified laboratories and food safety expertise should be involved where needed.
Can you investigate an existing stability problem?
Yes. A structured review can consider the formulation, production history, packaging, storage and available test results to help identify plausible causes and next steps.
When should shelf-life be considered?
Ideally during formulation and process development, then assessed using representative product and packaging as the product moves towards launch.
