Central Oregon is the epicenter of western junipers, Juniperus occidentalis.
In parts of central Oregon, western junipers extend for many miles/kilometers and are the only type of tree that grows there. The tree is barely present in Washington and absent in British Columbia.
In the Pacific NW, there are three species of juniper that attain "tree" size:
western juniper, Juniperus occidentalis, in high, dry, semi-arid deserts
Rocky Mountain juniper, Juniperus scopulorum, mainly on dry inland mountains
seaside juniper, Juniperus maritima, within sight of the Salish Sea
Apart from location, a telltale sign for distinguishing these species is barnacle-like glands that are abundant on the scales of western juniper. On Rocky Mountain juniper and seaside juniper, glands like this are either absent or inconspicuous.
All junipers are conifers, meaning that the seeds grow in cones. But juniper cones bear little resemblance to pine cones. Instead, they look more like small blueberries.
These cones are called "juniper berries" and contain usually 1 to 3 seeds each.
Gin is made from juniper berries (plus neutral agricultural alcohol).
Recently, distilleries have sprung up in central Oregon that produce gin from locally picked juniper berries.
The label on this bottle of Oregon gin reads:
Central Oregon is home to one of the largest Juniper forests in the United States, so it's no wonder we're big Gin fans. We pick fresh Juniper berries right off our local trees and use them to flavor our tasty Gin. We also add other botanicals to produce our uniquely flavored Gin. ...
I can vouch that central Oregon gin is tasty, either straight or in cocktails.
