  • Kahweol – Kahweol is a lipid found in the coffee bean and in brewed coffee. It is at higher levels in unfiltered coffee than in filtered, where it’s levels are very low. According to Wikipedia it is a diterpene molecule found in the beans of Coffea arabica. It is structurally related to cafestol. Recent research suggests that kahweol may have beneficial effects on bone by inhibiting osteoclast differentiation.[1] Another recent study confirmed that kahweol has anti-inflammatory and anti-angiogenic effects, offering a possible mechanism for the association found in epidemiological studies between consumption of unfiltered coffee and decreased risk of cancer.
  • Kent – Kent was the first useful CLR resistant cultivar; it was developed on the Kent estate in Mysore, India. Kent was widely planted but eventually was destroyed by a new wave of CLR; Coffee Leaf Rust fungus
  • Kenya – Kenya is the East African powerhouse of the coffee world. Both in the cup, and the way they run their trade, everything is topnotch. The best Kenya coffees are not sold simply as generic AA or AB. They are specific auction lots sold to the highest bidder, and heated competition drives the prices up. Their research and development is unparalleled. Their quality control is meticulous, and many thousands of small farmers are highly educated in their agricultural practice –and rewarded — for top level coffee.
    In general, this is a bright coffee that lights up the palate from front to back. It is not for people who do not like acidity in coffee (acidity being the prized bright notes in the cup due to an interrelated set of chlorogenic acids). A great Kenya is complex, and has interesting fruit (berry, citrus) flavors, sometimes alternating with spice. Some are clean and bright, others have cherished winey flavors.
  • Ketones – Along with Aldehydes, Ketones are important carbonyl compound that contribute over 20% to coffee aromatics. Formed from carbohydrates in the roast process, they result in aroma and flavor ranging from floral, herbaceous, buttery, caramel, vanilla, milky, saffron, beef, etc.
  • Kona – Kona coffee comes from farms along the Kona Coast on the Big Island of Hawaii. Coffee is grown at elevations relatively low compared to other coffee-growing origins; 800 to 1500 FEET above sea level, whereas coffee in Guatemala comes from 800 to 2000 METERS. The nicer coffees come from small family farms above the old road (Mauka coffees) and are grown from Kona Typica type seeds. Note that “Cona” is the brand of vacuum coffee brewer.
  • Kona Typica– Kona is a special cultivar, Kona Typica, a traditional varietal that cannot be grown at low elevations.
  • Kopi Labu – Pumpkin coffee. The term for the soft swollen coffee bean after it is wet-hulled out of parchment in Sumatra. The softness is like pumpkin meat.
  • KVW – A decaf plant in Germany specializing in the methylene chloride solvent method. KVW stands for Kaffee Veredelungs Werk. Solvent based methods have been shown to leave insignificant traces of chemicals that are fully dispatched by roasting the coffee.
