Green Coffee FAQ: Your Questions and Our Answers about the Basics of Green Unroasted Coffee!
Coffee doesn’t have to be rocket science. So why does that dude at the office party make it seem like it is? I know, I know … if you look around Sweet Maria’s site, it definitely looks like we (and those like us) are the ones turning coffee into something complicated.
For that, we apologize. Maybe it’s the caffeineAn alkaloidal compound that has a physiological effect on humans, and a bittering taste. It is found throughout the coffee plant but is more concentrated in the seed... but it’s easy to get excited about coffee. We try to make it accessible, while not dumbing it down. But in our classes and demos, we actually find that the most basic questions usually lead to the best conversations. With that in mind…
What coffee should I choose?
For beginning home roasters, I think it is best to start with a Green CoffeeGreen coffee refers to the processed seed of the coffee tree fruit. Coffee is a flowering shrub that produces fruit.

It’s really a combination of factors, not a single one. In marketing information, roasters and suppliers like to play up the Variety / CultivarCultivar is a term used interchangeably with Varietal in the coffee trade to indicate plant material, although there are distinctions.: The naming of a cultivar should conform to... of the coffee plant. But coffee isn’t like wine, and (with a few exceptions) variety isn’t producing a huge difference in taste as it would with a wine. Terroir, soil and climate matter, but again it’s a wine term that does not apply precisely. If I had to pick the factors not emphasized enough in the way people talk about coffee, I would say human labor, the huge effort to select ripe fruit and sort it, and processing method used to convert fruit to green beans, are the two most significant.

Single OriginSingle Origin refers to coffee from one location, in contrast to blended coffee. This term is particularly useful in discussing espresso, since most commercial espressos are made from... (SO) Espresso is incredibly satisfying, and our list tags coffees that work unblended as “Good for Espresso.” While much blending was done to bolster branding of coffee, there are some good reasons to blend, especially when balance is wanted along with moderate amounts of other attributes, such as brightness or fruit. We offer pre-blended green coffee, and our Monkey blend has been a big hit for years. To blend your own, perhaps use a mild BrazilBrazil is a coffee giant .

Dark Roast is for me! What green coffee roasts dark the best?
This can depend a bit; for a lot of body and low brightness (acidity), you might like Brazilian coffee, or Indonesians like SumatraIndonesians are available as a unique wet-hulled or dry-hulled (washed) coffees.

Roughly speaking there are 2 kinds of “fruited coffees.”
There’s a clean fresh type of fruit in coffee found in the best wet-processed coffees from high altitudes. Ethiopia coffees from Sidama, Yirga Cheffe, Shakiso or Agaro are great for this type of fruit. It’s also what makes KenyaKenya is the East African powerhouse of the coffee world.

Where do you guys get your coffee from?
Our coffee buyer travels to different coffee farms and mills around the world looking for good quality coffee, and checking our suppliers. In many cases we have direct contact with the farm or coop that produced the coffee, usually buying small lots ranging from 15 to 50 bags from one supplier. Other coffees we source from our exporter / importer network, but this represents a smaller amount of our purchasing volume.

As mentioned above, we have a drop down menu at the top of listings on the Green Coffee Offerings that allows you to view only those coffees that are organic, farm gateFarm Gate Coffee is the name we give to our direct trade coffee buying program.

Specialty coffee in general does not see the wholesale use of herbicides that are seen in other crops. The largest-scale producers tend to use more inputs on their crops because … guess what … they can afford them! Small-scale producers often can’t and look for alternatives. Lucky for us, we focus our buying on small-holder farmers and coops, not big agribusiness coffee operations.
Help! My favorite coffee is no longer available! What do I do?
(Tom addresses this question in the video linked above but here are some additional notes.) This happens all the time – mostly because we are dealing with small, specific lots of coffee. We carry not just coffee from a specific farm, but very often a specific cultivar (i.e. BourbonA coffee cultivar; a cross between Typica and Bourbon, originally grown in Brazil: Mundo Novo is a commercial coffee cultivar; a natural hybrid between "Sumatra" and Red Bourbon,..., pacamaraAs the name implies, Pacamara is a large bean cultivar, a cross between Pacas and Maragogype with unique flavor properties. This variant originated in El Salvador in 1958,..., etc) or picking or processing method. These are very limited lots of coffee, sometimes just a few bags, and often very unique, so we can sell out within a couple of months or faster.
When this happens, in most cases you want to look for a coffee from the same region or a nearby region. Then consider the processing method – this will greatly impact the flavor. A dry processed Ethiopian coffee will taste more like a dry processed Yemeni coffee, for example.
How long does green coffee last for?
The flavor of unroasted coffee is fairly stable when stored in a cool, dry place. Green coffee will not have a drop in cup quality from about 6 months, even up to 1 year from arrival date (every coffee we sell has an arrival date in the review). Compared to roasted coffee, that starts to fade in 7-14 days after roasting, that’s pretty good!
How should I store my green coffee?
All green coffee beans should be kept cool and dry at room temperature, and away from direct sunlight. The refrigerator is too moist for green beans and the freezer is too dry. In the trade, the general rule in terms of climate for green coffee storageGreen coffee is the dried seed from the fruit of a tree. In the past it was shipped in jute or sisal bags, which prevented coffee from becoming... is this: if it’s comfortable for you, then your coffee is happy too.

Transfer unroasted coffee to glass or our Ecotact coffee storageGreen coffee can be stored much longer than roasted coffee: Roasted coffee starts to lose its aromatics in 10 days after roasting. Green coffee can be stored months... bags to maintain cup quality for longer term storage.
Where can I buy green, unroasted coffee?
Sweet Maria’s of course! : ) There are other green coffee vendors online, and sometimes your local coffee roasterA machine for roasting coffee. Or the person operating it! The basic requirements for a coffee roaster are a heating element that gets suitably hot and a mechanism... will sell you some unroasted coffee if you ask nicely.
I had a certain coffee in years past that I really liked– when will it be available again?
We like to work with the same farmers year after year, because if they produce quality this year, it should be good next year and the year after. But things happen, and so the answer can be complicated. Whether or not we will have a specific coffee again depends on many variables such as weather, processing, shipping, and competition. Since we strive to provide the best green coffee available, we won’t bypass an amazing coffee we haven’t offered before. Tried and true coffees we have had year in and year out can be good, but not at the expense of ignoring quality and new flavors that are out there.

Nor is the... went through the wet processWet-processing starts by removing the outer skin of the coffee cherry with a machine called a pulper, then fermenting the remaining fruit (with green bean inside) in water... method before drying and becoming green coffee beans for export.

I bought green coffee but it looks more yellow than green! What’s up?
Green coffee is the term we use for unroasted coffee, because it usually is green-ish. The color of green doesn’t indicate quality, though some extra-dark green coffees might not have been dried or conditioned enough, and some pale green coffees might be old crop, or stored in hot conditions. Dry processDry process coffee is a method for taking the fruit from the tree to an exportable green bean. The whole intact coffee cherry is dried in the sun... coffees can look yellow, largely because the yellow-tinted silver skin (that comes off as chaffChaff is paper-like skin that comes off the coffee in the roasting process. Chaff from roasting is part of the innermost skin (the silverskin) of the coffee fruit... in roasting) still clings to the dry-process “green” bean. And it happens too with some honey-process or wet process coffees. It doesn’t impact the cup. Decaf is kinda brown-green too. More info here: Green Coffee, Defined
What is honey processThe honey process has nothing to do with honey other than the fact that they're both sticky! It's a term that became popularized in Costa Rica as another... coffee?
It is more of a marketing name than anything. In Brazil they called in “pulp naturalPulp natural is a hybrid method of processing coffee to transform it from the tree fruit to a green bean, ready for export. Specifically, it involves the removal... process” for decades. Honey-processing sounds sweeter though, no? But it has nothing at all to do with honeyIn coffee, honey-like sweetness is often found, but we use terms such as refined honey (highly filtered and processed) as opposed to raw honey rustic honey sweetness. This... from bees! It means the coffee is pulped of its skin, but the fruity layer is left on the seed as it dries, not fermentedAs a defect flavor, a fruit quality in a coffee that is excessively ripe, toward rotten. Fermented flavor can be the result of poor wet-processing, over-ripe cherry, or... off like in wet-processing. So honey process is something between wet- and dry- processing. Flavorwise too, it is in between the others, with less aromatics than some wet process, and more body and fruit … but not as much as full dry-process. Honey is called “miel” coffee in Spanish.
What’s the best coffee? Who grows it?
People do ask this, and I think it’s because coffee is brown, hot, and tastes the same to many people. But few people ask, “What’s the best wine in the world?” or “What’s the best tea?” Why? Because wine and tea are beverages that look different, where varieties of plants produce a totally different beverage, that looks obviously different in color etc, and is prepared / served differently. The distinctions between coffee are real too, but they are admittedly less dramatic, and they don’t look different. It’s all brown! Anyway, the answer to “What’s the best coffee in the world?” is, in fact, 42.

In FAQs you say green beans are good for 6 to 12 months. Can you comment on your beans that are more than 12 months from arrival date, e.g. Ethiopia: Uraga Tebe Haro and Nano Challo which both have arrival date Jan 2020. (today is Feb 2021).
Hey Peter, thanks for the heads up! We had a bit of an auto-fill error. Those two coffees were later arrivals, January 2021, not 2020! Appreciate the note and this info has been updated.

Anyway, the answer to “What’s the best coffee in the world?” is, in fact, 42. Love it, lets hitch hike some where.
Finally ! The answer…
sometimes it definitely seems like actually solving the coffee roasting puzzle requires traveling to another universe etc… lol
I hear the best coffee is actually found at the Coffee Shop at the End of the Universe.
Yes I hear the Gnab Gib blend is really quite nice!
Okay, I started roasting in around 1996, primarily Costa Rican Terrazu, Kenya AA, Ethiopian Yirgacheffe and Colombian Excelsior (I was using an I-Roast, a product that has gone belly-up since). Back then, the coffee was “brighter*, much brighter, and tasted much *fresher* than your roasted coffees (not to mention much cheaper… although I just did…=- ) I find today’s green coffee selections to be less than what I expected… they’re okay, but it taste like your usual roasted coffee. Am I asking too much to find some green coffee that is similar to the stuff 25 years ago? (note – I roast to a mediu-dark color, aboout a 6 or 7 on a scale of ten.)
Hi. The temps here are warming here in the Bay area (as you know), and I look forward to 70’s later this week.
The coffee I have been roasting are all id’d ‘good for ‘spresso’. My question, the coffee seems a little too bright (tangy) when I roast to FC+. Should I try slowing the final stage some, and letting it take a bit longer to hit 450 degrees, or is there something I need to do that I have overlooked? Using a freshroast SR500 with a temp probe down the center of the chaff basket cover. (Altiplano was one of the two I roasted this past week, with outside temps around the low 60’s)
For air roasts I would definitely slow it down a bit if the results seem too acidic, in particular at the end of the roast. I think you will find that helps balance out the espresso a lot!
I hope you brought your towel!
Do green coffee beans have to be roasted before grinding them?
Hi Tam, no, they don’t. I don’t have a lot of experience with grinding them myself, but I’d think any grinder with steel burrs would be safe. Not sure how long a blade grinder would hold up considering how dense some coffees can be!
You might look around online to see what others are doing, as I know it’s charted territory.
Best,
Dan
