[10:00 - 11:00] February Open Cupping

Hi everyone 👋

Our 2026 cupping sessions will mark the conclusion of our 2025 chapters on “Water” and “Grind Size.”

This year, we’re excited to open a brand-new chapter together with you: the Brew Ratio (Coffee-to-Water Ratio).

The brew ratio has always been a key factor in the brewing process—it often determines how far extraction and dissolution can go.

In immersion-style cupping, with its single-pour system, it also allows us to design some truly interesting and insightful extraction combinations.

If this topic interests you, we warmly invite you to join us this February ☕️

In our recent cupping sessions, we introduced a “Difficulty Bonus Challenge,”

and were pleasantly surprised by how much everyone enjoyed it!

This time, we’ll continue the tradition:

within several cupping sets, we’ll include a few challenge questions.

The participant with the highest score will enter a draw to receive G or U Series coffees as a prize！

We believe this challenge will become a long-term part of Oasis cupping culture.

Of course, the questions will remain a secret for now—

experienced tasters, you’re more than welcome to come and take on the challenge!
