I am trying to find some independent reviews of Nepali / Nepalese coffee on the web and so far I have not done too well. Here are two.
Lalitpur Coffee (Nepal)
Insiders count Lalitpur-coffee among the premium provenances in Nepal. Lalitpur is an excellently processed Coffee with a distinct unique character. Its growing area, some 40 kilometers South of Kathmandu, ranges from 800 to 1600 m.a.s.l. and comprises 8 cooperatives dedicated to organic shade. The year 2008 harvest resulted in 25 tons of Arabica, mainly exported to the U.S and Japan. When cupping a medium profile roast we were thrilled by the medium body, an unexpected aroma of nuts and rose water, and short but intense tangy highlight in a great lingering after-taste.
And, talking about coffee supplied by Himalayan Java:
Perhaps most remarkable attribute of this coffee is its fragrance. Unroasted, the green coffee effuses jasmine and sweet tobacco notes. Stunningly so.

Have not found too many more reviews (none) but these two at least show the promise held in the hills of Nepal. Maybe it is time for a coffee tasting festival here in Kathmandu.
