Choose a dark chocolate bar whose exact pack or product page makes a Fairtrade claim, rather than relying on a brand’s broader sourcing message. For a summer picnic, match the cocoa percentage to the group’s tastes, keep the bar cool and dry away from sunlight, and check its current allergen label before sharing.
Who is this choice for?
Fairtrade-first picnic shoppers
If Fairtrade is central to your choice, look for a claim on the particular bar. The Fairtrade Foundation distinguishes between its classic FAIRTRADE Mark and the Fairtrade Sourced Ingredient Mark, which identifies a specified Fairtrade-sourced ingredient.
Groups with different tastes
A bar that appeals to someone who enjoys intense dark chocolate may not suit everyone sharing the picnic. The cited Divine and M&S examples offer stated cocoa levels of 70%, 75% and 85%, giving you a concrete starting point for discussing preferences.
People sharing food with guests who have allergies
Check each guest’s requirements and read the current pack before serving. Dark chocolate, including bars described as vegan, can carry milk, nut or peanut allergen warnings.
What should you check?
Start with the exact bar’s Fairtrade wording, then consider taste, sharing and transport. These checks matter independently: a sourcing claim does not tell you whether a bar suits everyone at the picnic.

What to check |
Your needs |
| Fairtrade claim |
Read the exact pack or product page. According to the Fairtrade Foundation, the classic FAIRTRADE Mark covers ingredients that can be Fairtrade-certified; the Fairtrade Sourced Ingredient Mark identifies the ingredient named beside it. |
I want to know what the Fairtrade claim covers on the bar I am buying, rather than treating general ethical-sourcing wording as the same claim. |
| Cocoa level |
Compare the stated cocoa percentages and the group’s taste preferences. Divine lists a 70% bar, while the cited M&S product pages describe 75% and 85% bars. |
Will everyone enjoy a more intense bar, or would a 70–75% option be easier to share with this group? |
| Allergens |
Read the current ingredients and any precautionary ‘may contain’ statement for every bar. Do not use ‘vegan’ as a substitute for checking milk, nut or peanut warnings. |
If a guest has an allergy, I need the information for the actual bar we will share, not an assumption based on its cocoa percentage. |
| Picnic storage |
Check the bar’s storage instructions. M&S advises keeping its cited dark chocolate cool and dry, away from sunlight; keep bars wrapped and shaded during transport. |
I need somewhere to keep the chocolate out of direct sun until it is time to serve it. |
Picnic buying pitfalls
-
Treating every ethical-sourcing claim as Fairtrade
A brand’s farming or sourcing programme does not establish the Fairtrade status of each bar. Fairtrade Marks can also differ in which ingredients they cover.
If Fairtrade matters to you, check the exact product’s wording or mark and identify which ingredients the claim covers.
-
Choosing by cocoa percentage alone
The cited bars range from 70% to 85% cocoa, but the highest percentage is not automatically the right taste for a mixed group.
Ask what people enjoy before packing an 85% bar; consider a 70% or 75% option if tastes vary.
-
Assuming vegan means suitable for every allergy
The cited M&S and Montezuma’s dark-chocolate information includes milk, nut or peanut warnings alongside vegan descriptions.
Ask guests about allergies and check the current pack, including ‘may contain’ wording, before sharing.
-
Leaving bars in direct sunlight
M&S instructs shoppers to store its cited bars in a cool, dry place away from sunlight. A sunny picnic spot does not meet those storage conditions.
Keep the chocolate wrapped and shaded during the journey and until serving.
Brand references
Brand-wide sourcing messages and claims about individual bars answer different questions. Check the product you intend to pack, particularly if Fairtrade status is essential.
Divine
Divine lists a 70% Dark Chocolate 90 g bar and describes its business as farmer co-owned.
- Divine says it pays Fairtrade prices and premiums for every possible ingredient and shares profits with farmer co-owners.
- Check the chosen bar’s current pack and allergen declaration before sharing it.
M&S
M&S has product-level Fairtrade wording for the cited 75% and 85% dark-chocolate bars.
- Its product pages give cocoa percentages alongside storage and allergen information.
- Use the current pack for the final ingredient and allergen check.
Montezuma’s
Montezuma’s lists FitzRoy as a 74% dark-chocolate bar and describes its wider cocoa-sourcing commitments.
- The FitzRoy product information identifies it as vegan and gives a milk, nut and peanut trace warning.
- Do not treat the brand’s certified-cocoa or organic wording as a Fairtrade claim for FitzRoy without checking the exact bar.
Lindt
Lindt describes its own Farming Program and other responsible-sourcing standards.
- Lindt & Sprüngli reports that its cocoa products were sourced through those programmes or standards in 2025.
- That company-wide statement does not establish that a particular bar is Fairtrade-certified. Lindt’s UK allergen FAQ also says no Lindt product is guaranteed safe for people with nut allergies.
Hotel Chocolat
Hotel Chocolat describes a direct-farmer approach and its Rabot Estate in Saint Lucia.
- In its 2024 sustainability article, the company says it pays a premium for high-quality cacao.
- Its broader sourcing description does not establish Fairtrade status for an individual dark-chocolate product.
Green & Black’s
Green & Black’s lists a Dark 70% Chocolate 90 g bar.
- The named bar offers a stated cocoa percentage and pack size to compare with other picnic options.
- Check the exact bar’s current Fairtrade wording, ingredients and allergen information before buying it for the group.

This raspberry bar offers a fruit-accented 70% cocoa option. The Joybuy description calls the exact product Fairtrade-certified; check its current pack before sharing.

Common questions
How can I tell whether a dark-chocolate bar has a Fairtrade claim?
Check the exact pack or product page. The Fairtrade Foundation says its classic FAIRTRADE Mark covers ingredients that can be Fairtrade-certified, while the Fairtrade Sourced Ingredient Mark identifies the particular ingredient named beside it. A general statement about ethical sourcing is not the same as a Fairtrade claim for that bar.
Should I pack 70%, 75% or 85% dark chocolate?
Choose according to the group’s taste preferences rather than assuming a higher cocoa percentage suits everyone. The cited Divine 70% and M&S 75% and 85% bars provide different stated cocoa levels; ask whether people enjoy more intense dark chocolate before choosing an 85% option.
How should I carry dark chocolate to a summer picnic?
Keep it wrapped, cool and dry, away from direct sunlight. Those conditions reflect the storage advice on the cited M&S bars; check the instructions for the particular bar you take and keep it shaded until serving.
Is vegan dark chocolate suitable for guests with milk or nut allergies?
Do not assume so. The cited M&S vegan bars carry milk, nut and peanut allergy warnings, and Montezuma’s describes its vegan FitzRoy bar as possibly containing traces of milk, nuts and peanuts. Read the current pack for every bar you intend to share.
