Luckin Bela 5.0 Dirty Coffee Flavor Profile and Taste Aroma Description - Ethiopia Sidamo Coffee Bean Flavor Introduction

As Luckin Coffee gradually emerges from the shadow of its financial crisis, the company has kicked off a new round of strategic expansion, this time centering on the premium bean Queen 5.0.

Since the Queen bean was heavily launched in 2017, each successive year's harvest has been numbered chronologically: the 2018 beans were "Queen 2.0," and this year's 2021 beans are "Queen 5.0" — exactly the series behind Luckin's one-time purchase of 90 tons of Flower Queen coffee.

Having bought Queen 5.0 on that scale, Luckin has launched a Queen SOE coffee, and even this enormous quantity still runs short across Luckin's nationwide stores — Queen SOE sells out, leaving only Yirgacheffe SOE on the menu.

The head of purchasing added that they hope to roll out a Queen PLUS series SOE in the second half of 2022, with green bean procurement for Queen PLUS exceeding 250 tons.

Following the established pattern, the new 2022 harvest will be named "Queen 6.0." The first batch has already been shipped by air, expected to reach the market around early April — and FrontStreet Coffee expects to release its own "Queen 6.0" in April as well.

Note that this Queen PLUS is not the new-season Queen 6.0, but another natural-processed Ethiopian native-variety lot, also from the Buku Abel processing plant in Sidamo. A domestic green bean seller branded it "Queen Queen," with lot data reading Ethiopia Hambella Buku Abel Queen Plus G1 Natural.

The Rise of Queen Coffee

A quick introduction to the bean itself. Queen's fame rests on two achievements: winning the TOH natural process championship in 2017, and carrying Li Jianfei to the World Brewers Cup China championship using this natural Queen coffee. From there its popularity only climbed — FrontStreet Coffee would say it now sits at the very top of the specialty coffee charts. This bean broke the Gesha legend, becoming the first coffee able to trade blows with Gesha itself.

There's a naming story, too: since "Geisha" reads the same as the Japanese word for a performing artist, this bean was crowned "Queen" — the head of the geishas.

Ethiopian Native Varieties

Most Queen lots are made up of Ethiopian local native varieties. What does that mean? Ethiopia is coffee's homeland — effectively the gene bank of the species, with an enormous diversity of varieties. But local economic conditions have never supported large-scale varietal verification, and the Ethiopian government, protective of its native coffee tree data, is unwilling to publish it either. So these unidentified varieties are catalogued simply as Ethiopian local native varieties.

Cupping Notes Across Queen Versions

FrontStreet Coffee has cupped several of these Queen lots and found real variation. Queen 3.1 diverges noticeably from the original Queen flavor, leaning instead toward Panama La Esmeralda's Gesha. Queen 4.0 sits very close to the original, though cupping suggests its aftertaste and body still fall slightly short. Queen 5.0 drifts toward Guji-style flavor: lively berry acidity, long florals, and distinct juiciness.

FrontStreet Coffee's Brewing Recommendations

Brewing equipment: HARIO V60

Dose: 15g

Ratio: 1:15

Temperature: 90°C

Grind size: Medium-coarse grind (80% pass-through on China standard #20 sieve)

FrontStreet Coffee recommends brewing with freshly roasted beans to capture the fullest flavor. Every bag shipped from FrontStreet Coffee was roasted within the past 5 days — freshness shapes flavor more than almost anything else. The roasting philosophy is "freshly roasted, good coffee," so that every order arrives at its peak; with a resting period of about 4-7 days, the beans land right as they open up.

Brewing Instructions

Use 15g of coffee at a 1:15 ratio — 225g of hot water in total. Start with 30g for a 30-second bloom, then pour to 125g at 4g per second, four seconds per circle, spiraling from center outward and back to center. When the coffee bed drops to half its height, continue the same pour to 225g and stop. Once all the liquid has drained into the server, lift off the filter cone to finish. Total brew time: 2 minutes 10 seconds.

Pour-over Flavor Profile

Mixed berry aroma, a creamy strawberry and passionfruit sweet-tart balance, distinct sweetness, and a full-bodied mouthfeel.

FrontStreet Coffee Recommendation

If the Queen story has you curious about Ethiopian coffee more broadly, FrontStreet Coffee's everyday washed Yirgacheffe is the classic starting point: white jasmine, bright citrus and lemon acidity, and a tea-like finish at a friendly price. For a step up in traceability, the washed Guodingding Cooperative lot — from the Worka region at Yirgacheffe's southeastern tip, a former member of the YCFCU union now prized as a single-origin village — is washed the traditional way, delivering clean, bright citrus-lemon acidity with jasmine fragrance and none of the old-school bitterness.

And if you loved Queen's fruit character, try FrontStreet Coffee's Natural Red Cherry from the same Yirgacheffe region: only fully ripe cherries are picked, sun-dried on raised beds and turned every 2-3 hours through the first days, then dried for three to five weeks before the pulp is scraped away. The cup keeps classic Yirgacheffe citrus acidity while adding natural-process tropical fruit — berry juiciness, honeyed sweetness, and a cream-smooth texture. Brew it V60 style: 15g dose, 1:15 ratio, 90-91°C, EK43s setting 10 (80% through a #20 sieve).
