Win on purpose!

In this advanced session with Sam Corra and Jerome Rosler from Nucleus Coffee Tools, we break down how to design, validate, and execute competition‑ready roast profiles. Built for professional baristas, roasters, and coaches, this webinar connects green coffee physics, sensory goals, and stage workflow into a repeatable system you can trust on the world stage.You’ll learn how to translate sensory intent into curves, adapt profiles for espresso/filter/milk‑based service, control Maillard and development under time pressure, and leverage the Nucleus LINK Sample Roaster for precision and repeatability. If you’re targeting competitons like Barista Championships or Brewers Cup, this session gives you the frameworks and checkpoints to move from “good” to medal‑ready.👉 Nucleus Coffee Tools:👉 Roast Rebels — EU distribution of Nucleus Coffee Tools👉 Nucleus LINK Sample Roaster👉 Next webinars on Coffee RoastingChapter:0:00 Nucleus Coffee Tools and Coffee Competitions1:45 World Brewers Cup winning Profile3:10 Roasting Profile for Milk based Coffee5:28 Roasting Profile for Filter Coffee6:45 Martin Wölfl World Brewers Cup winning profile8:30 Roasting Profiles for Espresso9:50 Nucleus LINK Profiles in Development11:47 Eline Ferket's WBrC Profile14:50 Jason Bull's WBrC Profile18:31 Selecting Roasting Profiles for Cup Scores21:52 Get Roasting Profile Support from Nucleus Coffee Tools▬ About the Nucleus Link sample roaster ▬▬▬ The Nucleus Link is a highly accurate convection roaster. It has been specifically designed as a sample roaster - in particular, it allows the same roast to be produced regardless of external conditions. This makes it perfect for communication between coffee growers, traders and roasters, and as a sample roaster for farm visits.The unit comes in a shockproof box and with accessories to determine the density of the beans. It also comes with an app that selects the appropriate settings for the machine based on the altitude, type and density of the beans. Thanks to its ease of use, the machine is also suitable for ambitious and quality-conscious home roasters.You can find more about the roaster here: https://roastrebels.com/en/nucleus-link/▬ About this channel ▬▬▬▬▬▬▬▬▬▬▬▬At Roast Rebels, our mission is to make coffee roasting easy.
