Coffee Star Grading (CSG) 活動說明

【讓一杯咖啡，說出烘豆師真正想呈現的風味】

每一支咖啡的背後，都有烘豆師自己的理解與選擇。

你希望它明亮奔放，還是深沉飽滿？
希望消費者先感受到花果香氣，還是甜感、口感與悠長餘韻？
你所設定的烘焙方向，最後是否真的完整呈現在杯中？

有些風味沒有絕對的好壞，重要的是：這杯咖啡所呈現的結果，是否清楚、完整，也能讓人理解烘豆師想傳達的想法。

2026年，「咖啡烘烘烘－星級評鑑 CSG（Coffee Star Grading）」全面升級。

星級評鑑 CSG不是淘汰制競賽，也不是把所有咖啡排出名次，而是一套針對每一件咖啡獨立進行的專業感官評鑑服務。

我們希望透過一致的杯測流程、評審校正與感官評分，協助烘豆師重新看見一支咖啡在杯中的實際表現，並將專業的評鑑結果，轉換成消費者也容易理解的100分制與星級語言。

【每一件送評咖啡，都會得到完整結果】

無論最後取得幾顆星，或尚未達到星級門檻，每一件完成評鑑的咖啡都會獲得：

・八項感官評分
・轉換後的100分制成績
・咖啡風味與質地描述
・專屬評鑑報告
・該次評鑑證書

八項評鑑內容包括：

・Fragrance & Aroma 香氣
・Flavor 風味
・Aftertaste 餘韻
・Acidity 酸質
・Mouthfeel 口感
・Sweetness 甜感
・Balance 平衡性
・Overall 整體評價

沒有取得星級，不代表這次送評沒有成果。

你仍然可以透過完整成績與風味描述，了解這支咖啡目前呈現出的特色、評審實際感受到的風味輪廓，以及烘豆的方向，是否清楚地傳達到杯中。

因為你所支付的，不是一次爭奪名次的機會，而是一套完整的專業評鑑服務。

Let Every Cup Express the Roaster’s True Intention

Behind every coffee lies a roaster’s own understanding and choices.

Do you want the coffee to be bright and vibrant, or deep and full-bodied?
Do you want consumers to first notice its floral and fruity aromas, or its sweetness, mouthfeel, and lingering finish?
Does the final cup truly express the roasting direction you intended?

There is not always an absolute right or wrong when it comes to flavor. What matters is whether the coffee presents itself clearly and cohesively—and whether people can understand what the roaster intended to communicate.

In 2026, Coffee Boom Boom Boom’s Coffee Star Grading (CSG) receives a comprehensive upgrade.

CSG is not an elimination-based competition, nor does it rank every coffee against the others. It is a professional sensory evaluation service that assesses each submitted coffee independently.

Through standardized cupping procedures, calibrated judges, and structured sensory scoring, we help roasters gain a clearer understanding of how their coffee actually performs in the cup. The professional evaluation results are then translated into a consumer-friendly 100-point score and star rating.

Every Submitted Coffee Receives a Complete Result

Whether a coffee earns a star rating or has not yet reached the required threshold, every coffee that completes the evaluation will receive:

• Scores across eight sensory categories
• A converted 100-point score
• A detailed description of its flavor and texture
• A dedicated sensory evaluation report
• An official certificate of evaluation

The eight evaluation categories are:

• Fragrance & Aroma
• Flavor
• Aftertaste
• Acidity
• Mouthfeel
• Sweetness
• Balance
• Overall

Not receiving a star rating does not mean that the evaluation has produced no meaningful result.

The complete scores and sensory description will still help you understand the coffee’s current characteristics, the flavor profile perceived by the judges, and whether your intended roasting direction has been clearly expressed in the cup.

What you are paying for is not an opportunity to compete for a ranking. It is a complete professional sensory evaluation service.

【星級，是咖啡品質的溝通語言】

評審將從八個感官面向進行評分，再將專業結果轉換成消費者較容易理解的100分制。

達到相應品質門檻的咖啡，將取得對應星級；尚未達到星級門檻的咖啡，也會保留完整成績、風味描述、評鑑報告與證書。

星級不是與其他送評者比較後產生的名次，而是這支咖啡在本次評鑑中所呈現的品質層級。

我們不希望只用「喜歡」或「不喜歡」定義一支咖啡。

不同的烘焙方向，可能呈現完全不同的風味個性。評鑑真正關注的是：

・這支咖啡的風味是否清楚？
・不同感官表現之間是否具有連貫性？
・杯中的特色是否完整而具有辨識度？
・烘豆師想傳達的風味方向，是否能被感受到？
・這支咖啡是否具備足以與消費者溝通的品質？

CSG不是要求所有咖啡都變成同一種味道，而是希望每一支咖啡，都能更清楚地呈現自己的特色。

【從專業評分，到消費者看得懂的語言】

對烘豆師而言，八項感官成績與評鑑描述，可以成為檢視產品、理解杯中表現及調整烘焙方向的重要參考。

對咖啡品牌而言，證書、100分制與星級，可以協助品牌更具體地說明產品特色，讓品質不再只是一句抽象的形容。

對消費者而言，則能透過更直覺的方式，理解一支咖啡經過專業評鑑後所呈現的品質與風味。

CSG想建立的，就是專業評鑑、烘豆師與消費者之間的共同語言。

【讓年度成果，在咖啡展被看見】

取得星級認證的咖啡，除了獲得專屬證書與官方認證紀錄，也將有機會在年度咖啡展中公開陳列。

我們希望讓消費者不只看見一張證書，也能進一步認識：

・這支咖啡來自哪一個品牌
・烘豆師想呈現什麼樣的風味
・作品取得了什麼樣的評鑑成果
・這支咖啡為什麼值得被認識

年度重要成果也將於咖啡展舉行正式頒獎，透過實體獎盃與公開舞台，記錄烘豆師與品牌在這一年所完成的作品。

讓評鑑不只停留在一張分數表上，而是成為能被展示、被理解，也能長期留存在品牌中的品質紀錄。

一支咖啡不一定要贏過誰，才值得被好好理解。

如果你想知道自己的咖啡，在一套經過校正的專業感官評鑑中，會呈現出什麼樣的風味與品質；如果你也想確認自己設定的烘焙方向，是否真正傳達到了杯中——

歡迎把你的咖啡交給我們。

讓我們從杯中出發，看見這支咖啡現在的樣子，也讓更多人理解你真正想呈現的風味。

Star Ratings as a Language for Communicating Coffee Quality

The judges will evaluate each coffee across eight sensory categories before translating the professional assessment into a consumer-friendly 100-point score.

Coffees that reach the corresponding quality thresholds will receive their respective star ratings. Coffees that have not yet reached a star-rating threshold will still receive their complete scores, flavor description, evaluation report, and certificate.

A star rating is not a ranking created by comparing one submitted coffee with another. It represents the level of quality demonstrated by that coffee during its evaluation.

We do not want to define a coffee simply as “liked” or “disliked.”

Different roasting approaches can create entirely different flavor personalities. The evaluation focuses on questions such as:

• Are the coffee’s flavors clear?
• Are its sensory qualities cohesive and interconnected?
• Are its cup characteristics complete and distinctive?
• Can the judges perceive the flavor direction intended by the roaster?
• Does the coffee possess a level of quality that can be clearly communicated to consumers?

CSG does not require every coffee to taste the same. Instead, we want every coffee to express its own character with greater clarity.

Translating Professional Evaluation into a Language Consumers Understand

For roasters, the eight sensory scores and evaluation notes provide valuable references for reviewing a product, understanding its cup performance, and refining its roasting direction.

For coffee brands, the certificate, 100-point score, and star rating offer a more concrete way to communicate product quality—allowing quality to become something more meaningful than an abstract claim.

For consumers, these results provide a more intuitive way to understand the quality and flavor of a professionally evaluated coffee.

CSG aims to establish a shared language connecting professional evaluation, coffee roasters, and consumers.

Showcasing Annual Achievements at the Coffee Show

In addition to receiving a dedicated certificate and an official certification record, coffees that earn a CSG star rating may also be selected for public presentation at the annual Coffee Show.

We want consumers to see more than a certificate. We want them to discover:

• The brand behind the coffee
• The flavors the roaster intended to present
• The coffee’s evaluation achievements
• Why this coffee deserves to be recognized

Major annual achievements will also be honored during an official awards ceremony at the Coffee Show. Through physical trophies and a public stage, we will celebrate the coffees, roasters, and brands that have distinguished themselves throughout the year.

We want the evaluation to become more than a score sheet. It should become a lasting record of quality—one that can be displayed, understood, and preserved as part of a brand’s story.

A coffee does not have to defeat another coffee to deserve thoughtful recognition.

If you would like to understand how your coffee performs through a professionally calibrated sensory evaluation—and whether your intended roasting direction has truly been expressed in the cup—we invite you to submit your coffee to CSG.

Let us begin with the cup, discover what your coffee expresses today, and help more people understand the flavors you truly intended to present.
