Why are the chunks uneven?
Deliberately — it is a reference to inequality in the cocoa supply chain, which is the point the brand was founded on.
Is the cocoa fairly traded?
Sourcing and traceability are central to the brand and set out on the wrapper and on their own site.
Are there vegan bars?
The dark chocolate bars are the ones to look at. Check the individual wrapper, as recipes vary.
Do the bars contain nuts?
Several do, and others are made on lines handling nuts. Allergen information is on every wrapper.
What size are the bars?
Larger than a standard bar, which is why they work well for sharing or as a gift. The weight is on each product page.
