Alice Lascelles wrote:Instead, Rueller sells two rare varieties of bean that are naturally low in caffeine: laurina and aramosa. Laurina, an arabica-bourbon mutation, typically contains less than half the caffeine of a regular arabica bean. Caffeine is the coffee plant's natural insecticide, so low-caffeine varieties such as these are very hard to grow. They're low-yielding and vulnerable to pests - and therefore expensive. The Barn's Daterra Reserve (€18 for 250g), a blend of laurina and aramosa from the acclaimed Brazil grower Daterra, is a great brew with a nose-tickling toastiness and vibrant notes of pecan, orange peel and liquorice. When London-based coffee roaster Union launched a laurina last month, the first batch sold out in 24 hours.
