La Esmeralda (filter)
Los San Juanes (espresso)

Located close to the Three Thousand Thieves head office in Kensington is one of Melbourne’s best kept coffee secrets: Rumble roastery. A humble, modern warehouse on an unassuming side street is where the magic happens, thanks to founders Joe Molloy, Matt Hampton and Stan Bicknell. This is the second time we’ve featured Rumble, after being blown away in 2016 by their delicious coffee and passion for their craft.

This time around, Rumble have a one-two punch on offer, with both coffees from one of their favourite origins: Guatemala. The Central American country has been producing coffee since the 1850s, and always ranks among the very best for the amount of high-grade beans it yields. Although production is in decline lately, the quality and reputation of Guatemalan beans still stands strong. Almost 270,000 hectares of land are divided into eight coffee producing regions, feeding 4,000 wet mills and putting 44,000 coffee producers to work!

Our feature filter roast is a real pocket rocket from the world-renowned La Esmeralda estate. With notes of peach, nashi pear and nougat, it’s utterly delicious. One of the most highly praised growers in the world right now, La Esmeralda carefully processes at the wet mill, creating a unique profile for Guatemalan coffees. To get an intense and flavourful quality, cherries are selectively picked when uniformly fully ripe, then processed with great attention to detail: mechanically pulped, dry fermented for 12 hours and washed in the grading channel, followed by La Esmeralda’s drying patio, and raised drying tables for the microlots. With such a prestigious proven track record, we’re sure you’ll love this coffee as much as we do.

For the espresso, we’re showcasing the Los San Juanes. Featuring flavours of oranges, dates and honey, Los San Juanes is a new producer for Rumble that’s already standing out on the cupping table. Located in the county of San Antonio La Paz in the department of El Progreso in Guatemala (part of the mountain range known as Sierra de Las Minas), Los San Juanes goes from 1700 to 1900 metres in altitude. It’s the highest non-volcanic chain of mountains in Guatemala outside of the Huehuetenango Region. A micro climate of humid forest dominated by pine trees gives character to this new profile of coffee that we’ve recently started to discover and love.

If you’re brewing the Los San Juanes on a commercial espresso machine, Joe recommends a 20g dose, 42g yield over 29-31 seconds.

Unlike many other roasters in Melbourne who run a joint cafe / roastery, Rumble have opted to focus solely on roasting. “All we do is source coffee, roast it and get it out to the world. We love cafes but they take loads of time and attention, so we choose to spend that time on the coffee instead,” say Joe.

So although you can’t buy a latte from Stan, Joe and Matt at Rumble, they do offer weekly free cuppings, open to the public. To cup some new coffees from around the world, join the boys on Fridays at 3pm at 8 Thompson Street, Kensington, VIC 3031 (excludes public holidays).
