Common juniper displays a wide range of growth forms, from low-growing ground covers to small trees, depending on its environment. Its needle-like leaves grow in whorls of three and are sharp-tipped. The juniper “berries” are actually female seed cones, taking two to three years to fully mature. As they ripen, their color shifts from green to a dark purple-blue, and they emit the distinctive aromatic, slightly peppery scent.
The berries contain essential oils, tannins, sugars, and resins, giving them their unique flavor profile. While junipers are widespread, Juniperus communis is specifically renowned for its culinary application, especially in spirit distillation.
The use of juniper has deep historical roots. In various cultures, it was believed to ward off evil spirits and was used for its medicinal properties. Its antiseptic and diuretic qualities made it a popular remedy in traditional medicine for ailments like urinary tract infections, rheumatism, and digestive problems.
The distillation of spirits using juniper can be traced back to the Middle Ages, with the creation of early forms of gin in the Low Countries. It wasn’t long before the British adopted and popularized gin, with juniper berries being its defining ingredient.
Indigenous peoples of Alberta have historically used juniper for various purposes. Juniper branches and berries have been utilized in traditional medicines, and the wood, known for its resistance to rot, has been employed for crafting and tool-making.
