41673-1 – SPOT RCWHSE
Overview
This is a high intervention washed coffee, anaerobically co-fermented with jasmine flower extract, from Yunnan, China, produced by Aki Chen on his coffee community estate, Mountree Village.
The flavor profile is precise, clean, and ingredient (rather than process) focused. We taste extraordinary clarity of jasmine and green tea flavors, layered on top of classic chocolaty coffee, with hints of other regional products like lotus root and water chestnut.
Our roasters found that this Yunnan can go two ways: roast it lighter if you want it to pop on the table or charge hot with plenty of airflow and stretch out the Maillard phase for a subtler, syrupy cup of jasmine, green tea, and black sesame.
When brewed, it’s incredibly versatile and works well across all brew methods.
Taste Analysis by Isabella Vitaliano
Perhaps the magnum opus of the Crown Jewel program, this represents everything the team strives to source. Chinese coffee is historically difficult to source to the U.S market. There is little demand, it's expensive, and often the quality is not equal to the cost of production. It hits the trifecta of source rarity, intentional processing, and regional distinctness.
In a lot of ways, this coffee is exactly what you would expect. It has one of the cleanest jasmine notes you could find in a coffee -- perhaps the cleanest co-ferment note. While this may seem to sing only a single chord, there are subliminal textures of lotus, water chestnut, champagne, milk, and mojito.
On espresso, Asha found this coffee to lean almost extraterrestrial with notes like iris, silver, orris and mint. While most co-fermented coffees are already intended for a select crowd, you might think these flavor notes are taking it a little bit too far. I assure you that this is an excellent coffee meant to wow customers of all types. While it may not be for everyone, everyone can appreciate the clean, crisp perfume-like jasmine notes, botanical sparkle, and milk tones.
Source Analysis by Chris Kornman
Yunnan is saturated with flavor. Fresh lemongrass, vibrant chilis, and edible flowers adorn nearly every regional delicacy. There are dozens of wild edible mushrooms. The numerous ethnic minority peoples in the region bring influences to the cuisine that are reminiscent of the foods of Thailand, India, Laos, Vietnam, and Myanmar. The coffee here is no exception.
I was lucky to find myself traveling to the far reaches of the country in China’s southwestern-most region, to a semi-autonomous zone beyond the city of Pu’er (internationally famous for its fermented tea) to the little city of Menglian. I say little. It’s a backwater, as Chinese cities are concerned. A mere 800,000 in population, almost twice the size of Oakland, California.
In the city, an entire block is dedicated just to specialty coffee cafes, each serving their locally sourced Geshas and Catimors and co-ferments late into the night. On the outskirts, coffee grows in the hills alongside avocado and tea. It’s here that Aki Chen is encamped. Literally. He lives in a tent.
Once successful in business in the Tier 1 megalopolises in the east, an interest in specialty coffee sparked passion and a new career, one which initially saw him sourcing for one of Shanghai’s leading specialty coffee roasters, but then eventually, yearning for deeper connection to China’s agricultural communities, led him to uproot and move to Menglian. Here, he has established a coffee processing facility, coworking and event space, cafe, and who-knows-what-else in the coming years. He’s invested in land across the border in Myanmar to expand his coffee empire, while investing in the community in Menglian by providing education, processing, marketing, and placement services for the coffee growers in the region.
Aki was once a coffee buyer, including buying coffee from Royal. He’s now our newest supplier, in an up-and-coming region experimenting with some of the most cutting-edge techniques in coffee production today. There are parallel idioms in English and Chinese. Here, we say, to “come full circle.” In Chinese, the phrase 周而复始 (“zhōng ér fù shǐ”) indicates the end has come back to the start.
Aki’s experiments are wild, absolutely bending the mind and pallet. I tasted mushroom co-ferments and Bailey’s-aged coffee. However, for our first foray into Chinese coffee, we erred on the side of restraint and selected a jasmine-extract co-ferment. It’s one of our favorites of the year, in part because there is such precision of flavor, and in part because it has been inspired by the classic pearled jasmine green tea, famously produced in China. The iconic pairing was impossible to pass up.
Aki’s process began at Montree Village, harvesting ripe cherries and selectively choosing both by hand and by color sorter the ripest fruits. Thereafter, the coffee cherries are depulped and fermented with a jasmine flower extract for 24-72 hours (depending upon the intended flavor profile). After fermentation is complete, the coffee is washed and dried on raised beds for 14-16 days.
This is our first Chinese Crown Jewel. It’s the result of passion and labor, and a spirit of collaboration that Aki imbues in everything he touches. I’m extraordinarily proud to have filled my end of the bargain we made in March, by bringing it to California. I hope you enjoy this unusual spectacle of a coffee. While I don’t expect it to last long, I do expect there will be more where it came from in the future.
Green Analysis by Isabella Vitaliano
Moisture content is within average range, density is in the lower range, and these slightly larger beans are spread between 19-16 screen size. Elevation in the southern region of China is not particularly high, and so it makes sense this coffee would be of a lower density and larger screen size. Processing is immaculately done and Aki Chen has created some of the clearest co-ferment flavors I’ve ever tried; you won’t be disappointed by this lot.

Take a look at our roast profiles below, as they are constantly changing!
After having visited China’s production territories in Yunnan recently, it’s clear that there’s a sea change coming in the near future. For China, it’s already here. The country’s Baoshan, Lincang, and Pu’er regions have expanded their coffee program by orders of magnitude over the last 10 years, and the project has culminated in not only steady sourcing for domestic consumption of coffee, but also a thriving specialty market that looks beyond the border and into the cups of coffee connoisseurs worldwide.
While this coffee is sure to have jasmine floral notes due to the way it was processed, I wanted to try to emphasize the grape juice, cola, and palo santo notes that Asha mentioned in her analysis of the espresso. To get the more herbal side, I decided to use a slightly higher charge temperature, with plenty of airflow from the outset. This, I hoped, would help to accomplish those enviable notes.
My roast started with 473F charge temperature, F2 fan, and P6 power quickly ramped up to P8 at turning point. At peak rate of change, I increased fan to F3, adjusting to F4 after two minutes. There was a slight tendency for this coffee to eke up in rate of change, so around 365F I lowered power to P7 and increased fan to F5 after a bit longer in Maillard to really stretch it out before first crack. Just after first crack, I lowered power to P6 in anticipation of riding this coffee out just a bit longer, towards a higher finishing temperature. At 403F / 9:12, I dropped the coffee into the cooling tray and was surprised with how light the coffee still appeared. It was a fast roast, however I didn’t observe any uneven coloration in the roast. Peculiar, but not a problem in and of itself.
In the cup, my roast had subtle black sesame and cashew notes, a syrupy mouthfeel, and, of course, jasmine and green tea flavors. While this didn’t pop on the table as much as Doris’s lighter roast, it’s a case for a more subtle and texture-focused roast that will be more of a chugger than a sipper. There weren’t any smoky or roasty characteristics here, only textural changes.
I’d recommend this coffee for any preparation method, really. Drip coffee, espresso, and full immersion are all going to take you on a tasty and worthwhile journey!

Brew Analysis by Joshua Wismans
Part of the beauty of coffee and a joy of being in the industry for a long time is witnessing the slow evolution of what we serve and how we serve it. Part of this change is born out of human connection and the new people we meet along the way. China as an origin has made huge strides in the coffees they are producing and how they are processed. It’s a joy to serve this Yunan, our first Chinese coffee on the Crown Jewel menu. This coffee is expertly cofermented, and it translates to beautiful pour-over. There are a few different profiles that highlight unique characteristic of this coffee. This coffee is overall less soluble, so you’ll be utilizing a finer grind.
The first brew we fell in love with was a V60 that utilizes a lower coffee to water ratio of 1:16.67 and a lower TDS of 1.29. The cup was really clean and delicate, allowing the jasmine to be present, while supported by plum, melon, and orange blossom.
The second brew we landed on utilized a moderate coffee to water ratio of 1:15.79, but an even finer grind and a Kalita Wave as our flat bottom brewer. In this brew, we found more papaya, dried orange, and pistachio, with the jasmine being subtler than the other brew.
Ultimately this is a versatile and delicious coffee that can be expressed in a few distinct ways. We recommend a lower dose, fine grind, and a conical brewer for cleaner, jasmine forward brews, and a moderate dose, even finer grind, and a flat bottom brewer for bigger juicier brews where the takes a bit more of a backseat to traditional coffee flavors.
Espresso Analysis by Asha Wells
Such a pleasure working with a truly unique coffee like this, especially in the realm of espresso, what a treat! From the jump I knew this coffee was going to have me in a chokehold; I love jasmine flavored anything. And the first shot I pulled had me feeling like I was walking through a botanical garden with fresh and perfume-laden air.
My first recipe, with a 18.5 gram dose, 39 gram yield and taking 24 seconds. This shot was Welch’s Grape Juice all the way, so round and jelly-like, emitting flourishes of lychee, cola and marshmallow. Obviously jasmine itself was present, especially on the nose but on the tongue it was not too forward or blatant, rather, folded into a lovely bouquet.
After a few more shots and a finer adjustment to the grind, I found my next recipe. Dosed at 17.5 grams, yielding 36 grams, with 28 seconds on the clock. After my first recipe, I thought it couldn’t possibly get better, boy was I wrong. This shot was even more lustrous than the last, dripping in florals the likes of, iris, rose geranium, and palo santo. While floral and expressive, also present was a warming, savory balance of mezcal, palo santo and tamarind that gave this shot a depth that only be described as dazzling.
What a ride! What’s not to like about this coffee? I wasn’t sure how it would perform as an espresso but I was blown out of the water and would highly recommend this coffee for many different brew methods.
