Optimising your product without losing flavour

Posted on by WSS
There isn’t a brand in the world that doesn’t want to improve its products. That could mean making them healthier, cheaper, more sustainable, or in some cases, compliant with new regulations. The challenge is, making the necessary changes, without losing the taste consumers love – and that’s where product optimisation comes in. At Wirral Sensory Services (WSS), product optimisation is at the heart of what we do, helping food and drink companies adjust, reformulate, and innovate with confidence. In more detail: what is product optimisation? To keep things simple, product optimisation means refining a recipe, formulation, or process, in order to achieve the best balance between taste, texture, cost, and performance. This is necessary because sometimes brands need to:
  • Reduce sugar, salt, or fat content
  • Replace ingredients due to supply chain changes
  • Meet new sustainability targets
  • Improve nutritional profiles
  • Cut costs without hurting quality
It does come with potential problems though, because even a small tweak can dramatically change how a product feels or tastes. That’s why we use sensory and consumer research to ensure every change still meets customer expectations. Why optimisation matters more than ever Product optimisation is far more important than people realise, because of the following.
  1. Consumer health trends
Today’s shoppers demand healthier options – but they still expect great flavour. Reformulating to lower sugar or salt can make sense nutritionally, but only if the end product still tastes the same standard.
  1. Cost pressures
Rising ingredient and production costs mean brands must be efficient. Product optimisation allows you to identify the most cost-effective formulation that consumers still prefer.
  1. Sustainability goals
Many companies are shifting to more sustainable or locally sourced ingredients. Sensory testing ensures these swaps don’t compromise on quality or taste.
  1. Regulatory requirements
New government policies on sugar, salt, and additives are reshaping the market. Testing helps ensure compliance and continued consumer satisfaction. How WSS helps brands optimise products WSS’s expert team uses a blend of sensory science and real-world consumer testing to guide every stage of product refinement. For example, here’s how a typical optimisation project might unfold:
  1. Define the challenge WSS begins by understanding your goals: Is it about reducing calories, cutting cost, or matching a competitor’s flavour?
  2. Design the experiment We help develop several potential formulations – for example, five versions of a drink with varying sweetness levels.
  3. Conduct sensory evaluation Panels of trained assessors and/or target consumers taste each version under controlled conditions. They rate aspects like sweetness, texture, aroma, aftertaste, and overall liking.
  4. Analyse the data Advanced statistical analysis identifies which attributes drive preference – and which can be safely adjusted without hurting acceptance.
  5. Deliver clear recommendations You’ll receive an easy-to-understand report showing which version consumers prefer and why, along with actionable advice for product launch or reformulation. The result? Data-backed confidence that your optimised product delivers the same (or better) experience as before.
Small changes can often lead to a big impact Optimisation isn’t always about major reformulation. Sometimes it’s as simple as adjusting cooking time or temperature, switching to a different supplier or changing packaging materials that affect shelf-life or freshness. Even minor adjustments can affect aroma, mouthfeel, or perceived sweetness. WSS helps detect and manage those subtle differences before your consumers do. With over 25 years of experience in sensory and consumer science, our team works with major retailers, food manufacturers, and brands across the UK and beyond. Remember! Optimising a recipe doesn’t have to mean compromising flavour. With the right research and sensory insights, your brand can create products that meet modern demands, without losing the magic that makes customers come back.

Understanding the process: benefits of sensory science

Posted on by WSS

Have you ever taken a moment in your busy schedule to consider why some products become instant favourites, while others, barely make it off the shelf?

Well, that’s it’s not down to luck, it’s down to sensory science.

Behind every mouth-watering sauce, perfectly balanced soft drink, or satisfying snack, lies a story and sensory testing – which is essentially the art and science of understanding how people experience flavour, aroma, and texture.

It’s where at Wirral Sensory Services (WSS), this process has been perfected over decades, to help food and drink brands create products people genuinely love.

But, what exactly is sensory testing?

Sensory testing is all about people and measuring human perception. It’s about how we taste, smell, see, and feel products. It turns subjective experiences into objective and measurable insights.

At WSS, we use trained sensory panels and real consumers to evaluate products under controlled conditions. The goal? To identify what works, what doesn’t, and why.

This kind of testing goes far beyond a casual taste test. It’s a structured evaluation process that blends science, psychology, and consumer behaviour.

Why does sensory testing matter for your food or drink brand?

Well, there are numerous reasons. For example:

1. It reduces guesswork

Instead of relying on instinct or internal opinion, sensory testing gives you clear data about what consumers actually prefer. Whether you’re developing a new recipe or adjusting an existing one, you’ll know which version performs best.

2. It guards brand reputation

Every small change in ingredient or supplier can alter flavour or texture. WSS helps ensure your customers won’t notice – or better yet, that they’ll love your product even more.

3. It supports product launch success

Launching a new flavour? Testing it first with real consumers at Wirral Sensory Services’ head office, means that you can refine it before investing in full production.

4. Helping you provide a competitive edge

Through benchmarking, WSS compares your products against competitors, so that you know exactly how you stand out, or where you might be able to improve.

Step by step: the WSS sensory testing process 

So, how does this process really work then? Here’s how a typical WSS sensory study might unfold:

1. Define the objective Every project starts with a clear goal: are you testing overall liking? Comparing reformulations? Or even, evaluating packaging impact on taste perception?

2. Design the test WSS experts choose the right sensory method. From blind taste tests to descriptive profiling. They determine sample sizes, randomisation, and evaluation protocols to ensure reliability.

3. Recruit the right panel Depending on the study, panels may include trained assessors or target consumers.

4. Running the sessions Samples are served in controlled sensory booths, free from distractions, odours, and branding. Participants will then rate your product on factors like appearance, aroma, flavour and aftertaste.

5. Data analysis Using advanced statistical tools, WSS identifies significant differences and trends. For example, you’ll learn which formulation drives liking or whether consumers notice your recipe change.

6. Deliver actionable insights WSS will provide a clear, visual report with recommendations you can use immediately, whether that’s choosing the best formula or refining marketing claims.

Many people assume that sensory research is only for global giants, but it’s also known to be hugely beneficial to small and medium-sized food companies as well.

Whether you’re a start-up, or a regional producer scaling up, Wirral Sensory Services offers flexible testing options that fit your budget and goals. Even one well-planned test can save thousands in wasted production or unsuccessful launches.
