1. You need to be a verified member of the Mystery Coffee League Discord in order to participate. To be verified, you need to join the Discord server, buy a Mystery Coffee from the Roaster of the Month, and provide proof by submitting a ticket with your online receipt or a photo of the coffee.
2. Each member must submit their guess before the deadline for a given month. Deadline dates for each month will be communicated on the Discord server ending at 11:59 PM PST. Members may submit multiple guesses but only the latest guess will be counted.
3. You can score a maximum of 30 points in total for all correct answers. The scoring breakdown is as follows:
   • 1 point – Participation in a given month
   • 1 point – Continent
   • 4 points – Country of origin
   • 4 points – Processing method
   • 15 points (3 × 5 points) – Roaster tasting notes
   • 3 points – Varietal
   • 2 points – Altitude
4. The continent of origin should be selected from a pre-defined list which includes: South & Central America, Africa, Asia, Europe, North America, and Oceania.
5. The processing method should be selected from a pre-defined list which includes: Washed, Natural, and Honey. The processing method is not connected with the fermentation method.
6. Roaster tasting notes should be selected based on the official Mystery Coffee League Flavour Wheel. Only answers from the Wow wheel will be accepted. You can score a maximum of 5 points for one tasting note:
   • Outer ring: 2 points
   • Inner ring: 3 points
   For example: If the correct tasting note is "Lime" and your answer is "Mandarin", you'll get a total of 3 points for matching the inner ring ("Fruity"). If your answer is exactly "Lime", then you'll score the full 5 points.
7. In the case of a blend of varietals in the bag, selecting at least one correct varietal will result in scoring the full 3 points.
8. Altitude scoring is based on how close your guess is to the actual target:
   • An exact guess earns 2 points.
   • Up to 250m away, the score decreases linearly using the formula: 2 − (deviation ÷ 250). (For example: With a target of 1,250m, a guess of 1,200m is 50m away and earns 1.8 points.)
   • Guesses more than 250m away earn 0 points. This means the scoring range is 500m wide in total (250m below to 250m above the target).
   • A missing altitude guess earns 0 points.
   • Scores are rounded to the nearest 0.05 point.
9. At the end of each month, the standings table will be updated and winners for a given month announced. At the end of the year, the member with the most points will be crowned the Mystery Coffee League Champion. In case of a tie, tasting notes points will be used as a tie-breaker.
10. Participating members may win prizes at the end of the year based on total scores. For yearly prizes, only 10 out of 12 months will be taken into consideration. Your 2 lowest scores will not count towards the yearly prize, which means you can safely skip up to two months of participation.
11. All guesses are final. In case of any doubts on how to map your guess to available options, please reach out to one of our USA Coordinators on Discord.
12. Rules are subject to change.
