Product testing (CLT)

We test how consumers react to a product before you invest in its production and distribution.

Central Location Test product trials enable us to accurately assess the taste, functionality and consumer response to new recipes under controlled conditions before they are launched on the market. At Inquiry, we design these tests to provide manufacturers with clear guidance on which recipes, packaging and concepts have the greatest commercial potential.

We conducted that many thousands of quantitative interviews in 2024

When is a product test (CLT) the best approach?


“I don’t know which version of the product stands a chance of succeeding in the market”

Product testing reveals which formula or variant consumers will choose before you invest in production and distribution. It also identifies the specific reasons for acceptance or rejection: taste, smell, texture, appearance, and whether the product meets expectations.

“The team can’t agree on which version to choose”

Product testing provides objective data from a representative group of consumers โ€“ putting an end to internal debates and guesswork. It also reveals which version has the greatest potential within each target audience segment.

“I don’t know how my product compares to the competition”

Product tests compare your product with key competitors in both blind and branded conditions. They also identify specific attributes where you excel or fall short, and where to look for an advantage.

Decisions over reports

Data is only useful if it leads to action. Thatโ€™s why, instead of endless spreadsheets, you get the answers youโ€™re looking for.

A team that thinks alongside you

From our very first meeting, we focus on the decision you intend to make. We select methods and questions designed to guide you, step by step, towards achieving your goals.

Local insight, a broad perspective

We are a member of the international Ebeltof Group, which gives us access to the latest insights into global trends, which we then put to use for our clients.

Answers to frequently asked questions


Which products can be tested using the CLT method?

Using the CLT method, we test a wide range of FMCG products that require sensory or functional evaluation:
Food products:

Confectionery: chocolate bars, pralines, sweets
Dairy products: yoghurts, cheeses, quark, milk-based desserts, ice cream
Condiments: mayonnaise, ketchup, mustard, sauces
Fats: margarine, butter, oils
Spices and flavour enhancers: stock cubes, spices
Snacks: crisps, breadsticks, crackers
Processed foods: cold cuts, fish products, pรขtรฉs
Drinks: juices, flavoured waters, fizzy drinks, coffee, tea

Cosmetics and hygiene:

Body care: shampoos, conditioners, shower gels
Deodorants and antiperspirants
Body creams and lotions
Intimate hygiene washes
Care wipes (for babies, cosmetic)
Make-up remover pads

Household chemicals:

Laundry detergents (powders, capsules, liquids)
Cleaning products (all-purpose, for the bathroom, for the kitchen)
Wash-up liquid
Fabric softeners
Air fresheners

Specialist products:

Fragrance components (for companies such as Firmenich, Givaudan)
Products for the catering industry (new recipes, semi-finished products)
Dietary supplements

The CLT method works particularly well for products requiring controlled testing conditions (temperature, method of administration, standardisation) and for products with a short shelf life that are not suitable for home testing.

How does CLT differ from a home test (HUT)?

CLT (Central Location Test) and HUT (Home Use Test) are the two main methods of product testing โ€“ each has its own advantages and uses:
CLT โ€“ testing under controlled conditions:

Where: In a research studio/central location
Duration: One session (15โ€“30 mins)
Control: Full โ€“ temperature, method of serving, sequence, exposure conditions
Products: Food/drinks requiring preparation, products with a short shelf life, cosmetics for immediate evaluation
What we measure: Initial reaction, immediate sensory evaluation, comparison with competitors
Turnaround time: 1โ€“2 weeks
When to choose: When you need a quick decision, standardised testing conditions or a comparison of multiple variants

HUT โ€“ home-use test:

Where: At the respondentโ€™s home
Duration: Several days/weeks of use
Control: Limited โ€“ the consumer uses the product as they wish
Products: Everyday products (cosmetics, household chemicals, long-life food)
What we measure: User experience over time, acceptance in real-life conditions, ease of use
Duration: 3โ€“6 weeks
When to choose: When the product requires prolonged use (e.g. shampoo, cream, washing powder) or you are testing functional aspects

Which method to choose?

CLT โ†’ if you are testing taste, smell, initial reaction, comparing variants or need quick results
HUT โ†’ if you are testing the user experience over time, product effectiveness or acceptance in everyday use
CLT + HUT โ†’ when you want to assess both the initial reaction and long-term acceptance

When should I carry out a product test?

It is worth conducting product testing at several key stages of the product lifecycle:

1. Before launching a new product onto the market
Situation: You have a finished product or several variants and are planning to enter the market.
Why test: You verify whether the product has a chance of success before investing in full-scale production and distribution. You avoid the risk of launching a product that fails to meet consumer expectations.
Whatโ€™s at stake: Millions of zlotys in production, marketing and distribution costs.

2. When choosing between recipe variants
Situation: The R&D team has prepared 2โ€“4 product variants (different recipes, flavours, scents) and cannot agree on which one to choose.
Why test: You receive objective data from a representative group of consumers โ€“ you put an end to internal discussions and make a decision based on facts, not the teamโ€™s opinions.

3. Before changing the recipe of an existing product
Situation: You are planning to modify a product (reducing sugar/salt, changing ingredients, optimising costs).
Why test: You check whether consumers will accept the new version, whether the change will reduce satisfaction, and whether loyal customers will be put off by the new taste/smell/texture.
Risk: You will lose existing customers if the change is poorly received.

4. When testing product innovation
Situation: You are introducing a new product concept, a new category or an unusual combination of ingredients/features.
Why test: You are verifying acceptance of the innovation โ€“ are consumers ready for something new, do they understand the benefits, and is it not โ€˜too farโ€™ from their expectations?

5. When you want to check your position against the competition
Situation: Your product is on the market, but you donโ€™t know how it fares in direct competition with the category leader or new competitors.
Why conduct the test: You identify strengths (what to highlight in your marketing) and weaknesses (what to improve in the recipe), and you obtain a benchmark for your product strategy.

6. Before scaling up production or entering new channels
Situation: You have a product operating in a single channel (e.g. catering, local sales) and are planning to move into retail or export.
Why test: You check whether the product will work in a new context (e.g. in retail packaging, in a new region) and whether it requires adaptation.

7. After receiving negative feedback from the market
Situation: Sales are falling, youโ€™re receiving negative reviews, and the competition is gaining ground.
Why test: You diagnose the problem โ€“ is it a matter of the product (taste, quality), packaging, price or communication? The test shows what needs fixing.
When might it be too late to test?

The product is already in full distribution without prior verification
Investment in the production line has already been made
Contracts with retailers have been signed with no room for changes

The best time: When you still have room for adjustments โ€“ after the R&D phase, before full production and distribution.
