Experience Session.

A seed-to-cup experience of fine coffees.

In this experience, you will be welcomed into an exclusive session and together with Sam Corra, walked through the full journey of farming green coffee --> live roasting --> brewing and tasting. 

For each session, we have 2 opposite coffees from the same farm to showcase. You will experience what different processing methods highlight in the coffees from the same producer.

Stage 1. Intro. We will introduce you to the farms and focus on the ethos, values and processing details of the coffees featured. 

Stage 2. Live Roast. Sam Corra will roast the coffees live using the Nucleus Link.

Stage 3. Brewing. Together with Sam & Elysia, we will brew the roasted coffees with the Paragon brewer and chat about the brewing techniques and what qualities of the coffees we are looking to bring out.

Stage 4. Tasting. Together, we will taste the 2 coffees brewed, and have an interactive session to discuss our experience.
