Charleston Coffee Roasters Ethiopian Yirgacheffe Micro Lot Coffee Tasting Profile

Introducing our Micro Lot Series featuring small lot, single origin coffees grown in limited quantities on small farms in premium coffee growing regions around the world. Each coffee in our Micro Lot Series has a special story we’ll share, and features a lot number on the label, ensuring traceability back to its specific country, region, and producer.

Our founder, Lowell Grosse, spent 17 years in the coffee importing business prior to starting Charleston Coffee Roasters in 2005. Over the years, he built relationships with coffee producers at “source” in coffee growing regions from Central and South America to Africa and Indonesia and beyond. Lowell and our team of talented roasters personally select these unique coffees, and slow roast each Micro Lot to introduce you to some very special flavors from around the world.

We’ll offer new Micro Lots throughout the year, so you can enjoy each one-of-a-kind coffee while it lasts. But please order quickly if you’re interested as each Micro Lot is specially roasted in a limited supply. Once it’s gone, it’s gone!  

Discover our Micro Lot Coffee from Papua New Guinea

Papua New Guinea

Our medium roast Papua New Guinea coffee, Lot #NM49, is grown and processed in the Nebilyer Valley in Papua New Guinea and includes Typica, Bourbon, and Arusha bean varietals.  Grown at 5,200 feet above sea level, this coffee is sourced from smallholder farms from Ambra, Kelewa, and Wurup in the upper Waghi Valley region.  The coffee is processed at the Kuta Kofi mill where it is sorted and de-pulped before being fermented in vats for 36 hours. The coffee is then washed 3 times and then brought to large sun-drying fields where it is fully sun-dried on tarpaulins for 3 to 4 hours per day for a period of 5 to 10 days, depending on weather conditions.

Explore Ibisi-natural Coffee from Rwanda

Ibisi mountains

Our medium roast Ibisi-Natural coffee, Lot #22079D, is grown and processed on Ibisi Mountain in southern Rwanda.  This coveted red bourbon varietal is grown at an altitude at 5,500 feet at Bernard Uwitje’s farm.  The coffee is dried on raised beds for 10-14 days, using a natural process,  where the coffee is laid out to dry within the cherry.  This gives the beans their fruit-forward flavor with a delightful sweetness.  Bernard partnered with the Rwanda Trading Company to build his Ibisi Mountain washing station. Through RTC’s investments in agribusiness training programs during the past 10 years, producer partners have seen an 86% increase in farm revenue.
