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

{Open Cupping} Oasis Public Cupping – October Session

“What difference does the choice of pure water make on the sensory experience?”

This October, let’s explore the hidden influence of water together.

Date: October 12

Session 1: 10:00 – 11:00 (this page is for Session 1)

Session 2: 11:30 – 12:30 (please register on the Session 2 page)

Location: Oasis Coffee Roasters – Nanjing

No. 13-1, Lane 335, Section 3, Nanjing East Rd., Songshan District, Taipei

Theme: The Role of Pure Water in Brewing

At Oasis, all three of our cafés brew coffee with carefully calibrated water—created by blending pure water + fixed minerals + set alkalinity levels.

Last month, during a calibration test, we compared two different pure water sources:

• RO (Reverse Osmosis) pure water
• Brita-filtered pure water

The results sparked great interest among participants. So this month, we’ll share this experiment at our cupping!

On October 12, you’ll taste coffees brewed with water prepared from both sources and discover how different pure waters affect sensory perception in the cup.
