Coffee Star Grading (CSG) Submission & Annual Awards

CSG Overview

Coffee Boom Boom Boom’s Coffee Star Grading (CSG) independently evaluates each submitted roasted coffee through standardized cupping procedures, calibrated judges, and eight sensory categories.

The professional evaluation results are translated into a consumer-friendly 100-point score and CSG star rating, helping roasters understand how clearly their intended roasting direction is expressed in the cup.

CSG is not a ranking-based competition. Each coffee is evaluated independently according to its own sensory performance.

Every coffee that completes the evaluation will receive:

1. Scores across eight sensory categories
2. A converted 100-point score
3. A detailed description of its flavor and texture
4. A dedicated sensory evaluation report
5. An official certificate of evaluation

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

咖啡烘烘烘星級評鑑（CSG）繳件與年度大獎說明

星級評鑑簡介

咖啡烘烘烘星級評鑑 CSG（Coffee Star Grading）透過一致的杯測流程、評審校正與八項感官評分，獨立評鑑每一件送評熟豆在杯中的實際表現。

專業評鑑結果將轉換為消費者容易理解的100分制與CSG星級，協助烘豆師了解自己設定的烘焙方向，是否清楚地呈現在杯中。

CSG不是以排名為目的的競賽。每一件咖啡都會依照自身的感官表現獨立接受評鑑，不與其他送評咖啡競爭名次。

每一件完成評鑑的咖啡都會獲得：

1. 八項感官評分
2. 轉換後的100分制成績
3. 咖啡風味與質地描述
4. 專屬感官評鑑報告
5. 該次正式評鑑證書

達到相應品質門檻的咖啡，將另外取得對應的CSG星級；尚未達到星級門檻的咖啡，也會獲得完整成績、感官描述、評鑑報告與證書。

Frequently Asked Questions

Q1: When is the deadline for my coffee sample to arrive?

Participants may complete payment in advance and send their coffee sample when it is ready. You do not need to select or commit to a specific evaluation session at the time of payment.

Once the sample has been received, it will generally be assigned to the nearest upcoming evaluation session.

The 2026 evaluation dates are:

1. August 21–23
2. September 18–20
3. October 16–18

All samples must arrive no later than October 18, 2026. If you would like your coffee to be included in an earlier session, please allow sufficient time for shipping and sample processing.

Q2: Can I request a refund, postpone my submission, or transfer my registration?

Yes.

Participants may complete payment in advance and send their coffee sample at a later date. The actual evaluation session will be determined by the sample’s arrival date and assigned to the nearest upcoming session, so a separate rescheduling request is generally not required.

Refund requests are subject to a service fee equal to 10% of the original payment. Once the coffee has completed the evaluation, the payment is no longer refundable.

A registration may also be transferred to another participant. Please contact the organizer before the evaluation and provide the new participant’s name, brand name, email address, and coffee information so that the evaluation report, certificate, and official certification record can be updated. A registration can no longer be transferred once the coffee has completed the evaluation.

All refunds, postponed submissions, and registration transfers must be completed before the final evaluation session of 2026.

Q3: What happens if my sample is underweight, pre-ground, incomplete, or damaged during shipping?

The organizer will evaluate the sample based on its condition upon arrival and will make every reasonable effort to complete the evaluation without compromising the consistency and integrity of the process.

If the sample is slightly underweight, the packaging is lightly damaged, or some information is missing—but the evaluation can still be completed—the organizer may proceed with the available sample and contact the participant for any missing information.

If the sample’s condition materially affects the cupping process, or if there is not enough coffee to complete the official evaluation, the participant will be contacted and asked to send a replacement sample. Any additional packaging and shipping costs for the replacement sample will be the participant’s responsibility.

To support a consistent evaluation, please submit 227g of roasted whole-bean coffee. Do not grind the coffee before submission, and ensure that it is securely sealed for shipping.

Q4: Will the remaining coffee be returned after the evaluation?

Remaining coffee samples will not be returned by default. They will be managed and handled appropriately by the organizer after the evaluation.

If you require the remaining sample to be returned or have another special request, please contact the organizer before the evaluation. If the request can be accommodated, additional shipping, packaging, and staff handling fees will apply.

If no special request is submitted in advance, the participant will be considered to have authorized the organizer to handle the remaining sample according to the operational needs of the evaluation and related activities.

常見問題 FAQ

Q1：完成付款後，咖啡樣品最晚何時必須送達？

完成付款後，可依照自己的咖啡準備進度寄送樣品，不需要在付款時選定或固定評鑑梯次。

主辦單位收到樣品後，原則上會安排於接下來最近的評鑑日期進行評鑑。

2026年度評鑑日期如下：

1. 8月21日至23日
2. 9月18日至20日
3. 10月16日至18日

所有樣品最晚不得晚於2026年10月18日送達。若希望參加較早梯次，請預留物流及收件作業時間，提早寄出樣品。

Q2：付款後可以退款、延後繳件或轉讓名額嗎？

可以。

參加者可以提前完成付款，待咖啡準備完成後再寄送樣品。實際評鑑梯次將依樣品抵達時間，安排至接下來最近的評鑑日期，因此不需要另外申請改期。

如需退款，主辦單位將收取付款金額10%的退款服務費；一旦樣品已完成評鑑，即不再受理退款。

評鑑名額亦可轉讓他人使用。轉讓前請先聯絡主辦單位，並提供新參加者的姓名、品牌名稱、Email及咖啡資料，以利更新評鑑報告、證書與官方認證紀錄。樣品一旦完成評鑑，該名額即不得再轉讓。

所有退款、延後繳件與名額轉讓，最晚均須在2026年度最後評鑑結束前完成。

Q3：如果寄達的樣品重量不足、已磨粉、資料不完整或包裝破損，會如何處理？

主辦單位將以實際收到樣品時的狀態為準，並在不影響評鑑公平性及完整性的前提下，盡可能完成評鑑。

若樣品重量不足、包裝輕微破損或資料缺漏，但仍可完成評鑑，主辦單位將依現有樣品狀態繼續作業，並視需要聯絡參加者補充資料。

若樣品狀態已明顯影響杯測，或剩餘數量不足以完成正式評鑑，主辦單位將聯絡參加者重新寄送。重新寄送所產生的包裝及運送費用，由參加者自行負擔。

為維持評鑑的一致性，請寄送227公克完整咖啡熟豆，請勿事先研磨，並妥善密封包裝。

Q4：評鑑完成後，剩餘的咖啡樣品會退回嗎？

評鑑完成後，剩餘咖啡樣品原則上不予退回，並由主辦單位統一管理及妥善處理。

如有取回樣品或其他特殊需求，請於評鑑前事先與主辦單位聯絡。經主辦單位確認可安排後，參加者須另行負擔相關運費、包裝費及工作人員處理服務費。

未事先提出特殊需求者，視同同意由主辦單位依活動及評鑑作業需要處理剩餘樣品。
