Sampling for food and beverage brands
Grocery is decided in the aisle by people who already know what they like. Trial is the only thing that changes that, and content from someone else's kitchen is the next best thing.
Why trial decides this category
Food and beverage is the category where trial matters most and is hardest to buy. A shopper walks past your product forty times a year and never once considers it, because the thing they already buy is fine and the risk of a bad dinner is not worth it. Advertising can raise awareness of a product nobody has tasted. It cannot make anyone confident about the taste.
That is why sampling has always mattered here, and why the traditional version is so frustrating. A demo day gets a spoonful into a few hundred hands in one catchment on one Saturday, and then it ends.
theSalt runs it as a purchase instead. Real customers buy your product in their own weekly shop, cook with it or serve it the way they normally would, and post the moment to their own network. You get the verified trial, the content and the rights, and the content keeps working after the campaign closes.
Fitted to the weekly shop.
Nothing here asks a shopper to do something they would not otherwise do.
Brief
One product, the shopper you want, and the outcome your category manager cares about.
Match
An opt-in survey filters for people who already buy in the category and shop the right banner.
Buy
They add it to their own trolley. Proof of purchase is checked against the content they post.
Cook and post
It is used at a real table, then posted with the advertising label at first interaction.
Boost and report
The best content runs as paid media, and the readout covers trials, content and performance.
Where your shopper actually buys it.

The rule that changes the brief: children.
Advertising food to children in New Zealand is governed by the Advertising Standards Authority codes, and the definitions are stricter than most teams assume. A child is anyone under 16, not under 13. That single definition rules out a lot of casting and a lot of audiences that look harmless on a media plan.
It is handled at recruitment, not at approval. If the brief cannot be run without targeting people the code protects, we say so before anything is booked.
- A child is under 16. Not under 13, which is the threshold people usually have in their heads.
- Occasional products must not target children. Products that fail the FSANZ nutrient profiling standard are treated as occasional, and cannot be advertised to that audience.
- Audience composition is a targeting factor. A creator under 16, or one whose New Zealand audience is 25% or more under 16, counts as targeting children.
- The advertising label is not optional. Ad, Advert or Advertisement at first interaction. Gifted, collab and sponsored do not satisfy the rule on their own.
Food and beverage, counted.
Every result is labelled by the market it ran in.

What food and beverage brands ask us.
Can we run this for a product that is high in sugar or fat?
Yes, with care about who sees it. Products that fail the FSANZ nutrient profiling standard are treated as occasional products and must not be advertised to children, which in New Zealand means anyone under 16. That shapes recruitment, casting and audience targeting from the start.
Do customers have to buy at a particular supermarket?
Only if the brief says so. If a retailer-specific result matters, recruitment can be filtered to shoppers of that banner. Otherwise they buy wherever the product is ranged.
Can the content mention a price or a promotion?
Only where the claim can be substantiated at the time it is made. The Fair Trading Act treats an unsubstantiated representation as a problem even if it later turns out to be true.
What if someone posts something negative?
Then that is what happened, and it is worth knowing. We do not script opinions. Content that does not meet the brief is not licensed, but a lukewarm review is data rather than a failure, and it is usually the most useful line in the report.
