Topic: Bean Types (9 msgs / 211 lines)
1) From: John and Emma
Ok all you knowledgeable wizards out there.
I know there are various coffee plant species such as:
Coffea arabica, Coffea benghalensis, Coffea bonnieri, Coffea canephora,
Coffea congensis, Coffea excelsa, Coffea gallienii, Coffea liberica, Coffea
mogeneti and Coffea stenophylla. That's the end of my knowledge.
The ones we can get at SM are C. arabica, C. canephora  (also known as C.
robusta) or C. liberica? Are there others?
How about types of beans? We get Bourbon, Longberry, Peaberry and
Yirgacheffe. What others are available? Can someone explain what these are
and their differences?
I don't have enough other things keeping me busy (lol) so I'm trying to just
learn. Actually I'm always working and when my mind wanders I start thinking
about these kinds of questions and just want to learn more.

John,
Whenever I want to know anything about coffee, the first place I look is sweetmarias.com Coffee Library. However, I couldn't find anything there that directly answers your questions. Your best bet is to read through Tom's green coffee pages. In the top right corner of each description is a box that lists the cultivar(s) in that offering, as well as grade, region, appearance, etc. As far as I know, they are all C. arabica except where noted otherwise, as in India Anokhi Liberica and those under the Robusta heading. I don't know how to describe the differences among the cultivars, but I bet there are some on this list who can....

OK- you can stay, John.
This sounds like a loaded question; maybe a magnet for curriculum
submissions to SMU, where all can learn about Coffee. It's art based on
science.

The Longberry beans  are longer than usual.
The Peaberry's beans are smaller than usual.

Here is a good read from the SM libraryhttp://www.sweetmarias.com/coffeespecies.htmlMaragogype is another from Brazil and produces "elephant" sized beans. Taste
real good as well.
Hope this helps

Thanks everyone for your reply.

This is finally dawning on me, that all coffee arabica is essentially coming
from the same plant (i.e., same genus/species) and that all the differences
we are tasting from the various coffees is essentially "terroir."  Is that
right?  Or are the different coffees really coming from different species of
plants?

well, aside from the three species which are commercially cultivated  
(Arabica, Canephora, Liberica) there are cultivars of each species.  
For example, Arabica has cultivars Typica, Bourbon, Catimor, Catual,  
Caturra....
Here's an interesting article, though I wish the graphics were  
readable....http://www.indiacoffee.org/newsletter/2008/jan_feb/coffee-family.html-
