In this article, we tell the story of the long and slow process of creating a new and super bee, the Buckfast bee, which has become one of the most used bees by beekeepers around the world. This success story is the result of a meticulous and laborious work of selection, crossbreeding, observations and travels, carried out throughout the 20th century by a monk from Buckfast Abbey in the south of England, called Brother Adam. Strain and brand, nature and cultivation, the Buckfast bee embodies the two simultaneously, a nature-cultivational bee. And yet it is this farm animal, regardless of the strain, which has become a guardian and emblem of our biodiversity.
