We’re an independent coffee roastery in Jersey. What started in 2023 with three friends and one roaster has grown into a team sourcing and roasting coffee for homes, cafés and businesses across the island.
Luke followed a job to Jersey in 2004, selling Canon copier equipment. Six years later he set up Caffeine Mechanics with Adam, supplying coffee machines across the Channel Islands, which was a natural segue into the idea, and eventual birth, of Rock Roasters. When he’s not ferrying the kids between sports clubs, he’s probably watching some sport himself or cooking something up in the kitchen.
Go-to drink: a cortado. It’s a short drink, so the coffee has to be the best it can be.
Bill has been obsessed with coffee for years, with experience in London, Wellington in New Zealand and back home in Jersey, and has been roasting for around 15 years. He loves sharing his passion with anyone who’ll listen and helping people learn more and ask questions about coffee. Away from the roastery, he’s in or on the water, swimming or surfing around the island. Family is everything to him, and his children often lend a hand in the roastery, trying out new brews.
Go-to drink: a bold Colombian through the AeroPress, preferably made on a campfire.
Adam co-founded Caffeine Mechanics with Luke in 2010, supplying and servicing coffee machines across the Channel Islands, and has spent the years since inside more café kitchens than he can count. Rock Roasters was the obvious next step: roasting the coffee that goes through the machines he already looks after.
Go-to drink: to be confirmed.
Mutiso joined as head roaster in April 2024 and runs every batch that leaves the roastery, from profiling new arrivals on the Bellwether to keeping Rosie’s production roasts consistent week to week. He’s the reason the same coffee tastes the same in January as it did in June.
Go-to drink: to be confirmed.

Read the story
Rock Roasters started in 2023 with three friends, Luke, Adam and Bill, one roaster and a belief that Jersey deserved great coffee roasted on the island.
Since then there’s more experience behind the business, a growing team and a much clearer idea of the kind of coffee company we want to be. We’re less interested in saying what people want to hear, and more interested in giving them something real: why we bought a coffee, what we know about it and why we think it’s worth drinking.
We care a huge amount about sourcing and roasting. We just don’t make a show of it. Things feel relaxed because a lot of thought has gone in behind the scenes, and there’s always more to learn.
Tell us what you like and we’ll point you to a coffee, or have a look at what we’re roasting this week.
