Single-origin is a sourcing description whose exact meaning should be explained by the seller. It can refer to a country, region or more specific source; the phrase alone does not tell you how narrowly that origin has been defined.
Origin is different from ingredient count
A single-ingredient tea describes what is in the packet. A single-origin claim describes where the material comes from. Those are separate questions, so one phrase should not be used as proof of the other.
Ask what the origin claim covers
Look for a stated location and an explanation of whether it applies to every ingredient or a named component. A broad brand story is not automatically a product-level sourcing guarantee. Ask about the exact packet if the distinction affects your purchase.
Read K&M's sourcing story separately
K&M introduces its Caribbean growing connections and London preparation on its website. That background can help you understand the business without assigning an unverified single-origin label to every item. Use the individual product description for the details of a particular tea.
