The Philosophy Behind Sofia's Emerging Specialty Coffee Labs

Across the Atlantic, SPRO Coffee Lab opened its newest location at 201 Spear Street in San Francisco's Financial District at the end of July 2026. Founded by Rich Lee and his wife Liza in 2017 as a single coffee trailer with no outside investment, SPRO has grown into something more considered: a model for how specialty coffee can feel "exciting without feeling intimidating."

The principles behind SPRO's approach translate directly to what Sofia's best coffee labs are beginning to understand. European sourcing, neighborhood integration, hospitality-first thinking, and the conviction that exceptional coffee should never feel exclusive.

Sofia's specialty coffee scene, now home to over 60 specialty cafes, is moving past Instagram-driven cafe culture. The question is no longer "how do we look like a third-wave cafe?" but rather "how do we build spaces that belong to this city?"

At SPRO's new location, the ceiling became what Lee describes as "almost an art piece and a mission statement at the same time." He worked with architect Lincoln Lighthill, who designed some of the original Blue Bottle cafes, to create a space where the room itself communicates values before guests reach the counter.

This principle matters in Sofia. When a cafe invests in lighting, flow, and materials, it signals care. The physical space becomes the first conversation with the guest.

The bar at SPRO is designed for a three to four barista workflow, with a dedicated steam wand positioned near the register to keep drinks moving. This is hospitality engineering, making the experience smoother while keeping technical complexity invisible.

SPRO's menu draws from roasters across Europe: Barcelona, Copenhagen, Amsterdam, Paris. About half the menu features Gesha and other rare coffees. The philosophy is clear: "Someone can walk in for something familiar and comforting, but also have access to coffees that are usually much harder to find."

In Sofia, roasters like Blue Bag Specialty Coffee are adopting a comparable approach. Working directly with verified farms, focusing on peak-ripeness beans, and building relationships that prioritize quality over volume. Like SPRO's model, this sourcing philosophy extends beyond the roastery into the cafes that serve these coffees.

Roasters from Berlin, Copenhagen, and Amsterdam are a short flight away. The question is not access but curation: which coffees tell a story worth telling, and how do you present them without making guests feel they need a certification to order?

SPRO defines sustainability in two dimensions: environmental and human. They do not charge extra for milk alternatives, since dairy represents one of the largest parts of a cafe's environmental footprint.

On the human side, sustainability means building a business that supports staff, vendors, and the city over time. "Independent cafes are not easy to operate, especially in San Francisco," Lee notes. The same applies to Sofia, where rising rents and labor pressures challenge even the most passionate operators.

A cafe that burns through staff to maintain margins is not sustainable, regardless of its compostable cups.

SPRO's new space involved Strada as a partner, Tinkering Monkey for signage, Coffey Custom Builds for custom furniture, and Espresso Services Inc. for bar design. The cafe is, as Lee puts it, "very much a collective effort."

Sofia's coffee labs are beginning to understand this. The best spaces emerge from collaboration between roasters, designers, craftspeople, and the broader coffee community.

The model taking root here is not a copy of San Francisco or Brooklyn. It is an adaptation: European sourcing principles, Bulgarian hospitality traditions, and the specific rhythms of a city still discovering what specialty coffee can mean.
