- Nematodes – Nematodes are a diverse phylum, but in terms of coffee agriculture, there are both beneficial and negative-acting nematodes. Depending on the species, a nematode may be beneficial or detrimental to plant health.
From an agricultural perspective, there are two categories of nematode: predatory ones, which will kill garden pests like cutworms, and pest nematodes, like the root-knot nematode, which attack plants.
Predatory nematodes can be bred by soaking a specific recipe of leaves and other detritus in water, in a dark, cool place, and can even be purchased as an organic form of pest control. Rotations of plants with nematode resistant species or varieties is one means of managing parasitic nematode infestations. For example, marigolds, grown over one or more seasons (the effective is cumulative), can be used to control nematodes. Another is treatment with natural antagonists such as the fungus gliocladium roseum.
- New Crop – Refers to fresh shipments of green coffee within the first month or two of the earliest arrivals … not quite the same as Current Crop.
- New York “C” – The New York “C” market is the NYBOT (New York Board of Trade) trading platform for arabica coffees that determine base contract pricing. Prices on coffee futures are fixed against the C market.
- Nicaragua – Nicaraguan coffees from the Segovia, Jinotega and Matagalpa regions are underrated. They often possess interesting cup character along with body and balance, outperforming many other balanced Central American and South American high-grown coffees in the cup. Nicaragua coffees have a wide range of flavor attributes: Some cup like Mexican coffees from Oaxaca, others like Guatemala. Some are citrusy and bright, such as the coffees of Dipilto in Nueva Segovia department. For me, Jinotega and Matagalpa coffees can demonstrate their remarkable versatility in a wide range of roasts, from light City roast through Full City and into the Vienna range. The botanical cultivars utilized are traditional: Typica, some Bourbon and Maragogype dominate, along with Caturra and Paca. There is some of the dreaded Catimor varietal, but many farms have removed it after the “catimor craze” 10-20 years ago.
Good Nicaraguan coffees are considered a “classic” cup: great body, clean flavor, and balance. They are unique among Centrals in the fact that the highest grown (SHG grade: Strictly High Grown) do not develop the pronounced and sharp acidity of other Centrals. In season, we offer some new “exotic” cultivar coffees too, a Pacamara Peaberry , a longberry “Java” cultivar, and the large bean Maragogype. Pulp Natural process is also a variation that gives the cup great body and a slightly rustic fruited layer.
- Nitrogen Flushing – Pushing nitrogen, an unreactive gas, into a bag of coffee to force out oxygen, which is more reactive. Nitrogen flushing is often done as part of vacuum packaging, since vacuuming out oxygen is not sufficient to remove all oxygen in a bag.
- Nutty – Nutty is a broad flavor term, reminiscent of nuts. It is tied intrinsically to roast taste and the degree of roast, since a coffee that cups nutty at City+ will not be so at FC+. Nutty is usually a positive term but varies greatly as there are so many forms: hazelnut, walnuts, peanut, cashew, almond, etc. Occasionally, nutty can be a negative taste term, especially if it is out of character for a coffee. Some lower grown coffees can have less favorable nut flavors that imply a softness in bean density, and lack of quality. Nut skins is also a flavor tied to a drying, slightly astringent mouthfeel.
