Here are some ingredients that belong in your gin: juniper, lemon, cinnamon, coriander, orange, cardamom, nutmeg, grains of paradise, almond, ginger, licorice, elderflower, angelica and hibiscus.

Here’s an ingredient that decidedly does not belong in your gin: motorcycle.

You know that motorcycle is not an acceptable botanical, and I know that motorcycle is not an acceptable botanical, but does Uwe Ehinger know? I’m afraid to ask. He’s the bearded German badass who, for decades, has dug through garages around the world for lost motorcycle relics. Ehinger has spun his pursuit into not just a killer nickname (“The Archaeologist”), but a legitimate custom shop, Hamburg’s Ehinger Kraftrad, where he fashions the antique parts into bigger, bolder bikes.

But Ehinger isn’t content to sit on his laurels, because now he’s trying his hand at a stranger pastime: producing a premium dry gin flavored with the spirit of rare, original engine parts of three Harley-Davidson models. Sure. Ehinger’s gin, naturally called “The Archaeologist,” employs 1939 Flathead camshafts from Mexico, 1947 Knucklehead screw-nuts from Chile, and 1962 Panhead rocker arms from South Korea, per a press release.

“Everything I do is a tribute to the past,” Ehinger says in the menacing voiceover to this trailer for the spirit, below. And that’s as good an explanation as we found for why he decided to make gin out of engine parts. So it’s best to reserve judgment and just focus on the other cool shit that you’ll receive when you buy this gin, which, again, is made from engine parts.

Each bottle is meant to look like the original packing of the Harley-Davidson parts, culled from selected cardboards and colors and printed on an original Heidelberg Tiegel printing press from 1931. The bottle is then wrapped in a wax paper that tells the story of its discovery and finished with a hand-stamped seal and tag featuring the serial number of the engine part inside.

We haven’t tried The Archaeologist, because Ehinger reserved the first batch for his most loyal customers and served it in his garage. But he’s already taking orders for the next series on his website. Should you ever procure a bottle and wonder if you’ll throw up for consuming presumably dirty old engine bits, rest assured: Ehinger specially cleaned and sealed the engine parts and sealed them with a tin alloy to make them safe to be utilized in a drink–which means, this is the only spirit to be able to cure anemia.
