Sofiya, our Head of Coffee.
From sourcing green beans to fine-tuning roast profiles at our Forest Hill roastery, Sofiya oversees every single step of what goes into your cup.
For her, roasting isn’t about forcing a flavour, it’s about discovering what makes each lot special and letting its natural characteristics shine through.
Simply put, without her we won’t have the 15grams coffee you know and love!

✨ ⛰️Introducing La Cima, a bright and juicy selection from the high altitudes of the northern Andes.
Think crisp apple and white grape acidity, rounded out by a deep brown sugar sweetness. Clean, complex, and perfect for your morning filter brew. 🍎🍇🍯
Produced by small-scale farmers in Cajamarca, this lot underwent a precise 30-40 hour fermentation to deliver a cup with exceptional clarity and vibrance.
* Origin: Peru
* Process: Washed
* Taste: White Grape • Apple • Brown Sugar
