Boomsma Claerkampster Cloosterbitter

Boomsma Claerkampster Cloosterbitter is not merely a spirit but a journey through time. Its roots stretch back to the 1400s, when Brother Jacob of the Claerkamp monastery roamed the Frisian meadows gathering herbs to macerate in neutral spirits. Today, the Boomsma family preserves that secret recipe with unwavering care. Seventeen botanicals are hand-harvested—nettles, daisies, cloverleaf, mint, dandelion, gentian and others—and each herb is macerated separately before being artfully blended into a complex yet harmonious whole.

The result is a strikingly green bitter that looks as dramatic as it tastes. Aromas of green herbs and subtle mint mingle with notes of anise, gentle bitterness from gentian and a warming whisper of ginger and spice. There is a honeyed sweetness beneath the surface that softens the initial intensity and leaves a lingering dry finish, lightly reminiscent of licorice or black pepper.

At 40% ABV, Cloosterbitter offers a refined herbal punch without overwhelming heat. Many bartenders consider it a refined alternative to Green Chartreuse in cocktails such as the Last Word or Bijou. Its flavor is more approachable, with greater mint clarity and a smoother finish, and it comes at a fraction of the cost, making it a smart addition to any bar cart.

Whether savored neat as a digestif, poured over ice, or used in mixing, Cloosterbitter brings layered herbal richness to the experience. Try it in classic cocktails in place of heavier spirits—it elevates drinks while balancing potency and elegance. Its bold herbal notes also pair beautifully with dark chocolate, rich cheeses and cured meats, making it equally suited to contemplation or conviviality.

Boomsma Claerkampster Cloosterbitter is a modern-day expression of an age-old recipe. It celebrates tradition and craftsmanship in every bottle, delivering vivid color, botanical intensity and intriguing versatility. Perfect for adventurous drinkers, cocktail aficionados and lovers of herbal spirits alike—its balanced bitterness and historical pedigree make it a standout choice for those seeking depth, story and flavor in one captivating elixir.
