A further 3 facts on this page were read from part of the shop page that holds no sentence — a menu or a product grid — so there is nothing to quote for them.

Taken from the roaster’s own pages, and nothing here has been verified by us or by an independent body. What we store is a passage of page text cut around the fact, so one shown with an ellipsis is a passage we cannot see the start or the end of; only the fully quoted ones are complete sentences.
