GABEE's Rainbow Seven Coffee Series Explained

Coffee lovers often ask: how can a single cup capture a mood, a place, or even a season? For over a decade, GABEE—founded by veteran roaster Lin Tung-Yuan—has answered that by curating a complete, concept-driven coffee series built on direct relationships with farms and precise roasting. Their 'Rainbow Seven Coffee Series' isn’t just a collection; it’s a curated journey through seven defined coffee experiences, each designed to highlight a unique flavor profile, processing method, or cultural inspiration.

In short, GABEE’s Rainbow Seven Series includes seven distinct coffee concepts: Annual Memorial Recipe, Natural Process, Northern Italian Espresso, Single-Origin Espresso, Washed Process, Southern Italian Espresso, and Honey Process. Each serves a specific taste goal, from recreating holiday emotions to highlighting fruity washed coffees or bold southern Italian roasts.

What Is the GABEE Rainbow Seven Coffee Series?

The GABEE Rainbow Seven Coffee Series is a thoughtfully assembled range of seven coffee concepts developed by GABEE, a specialty coffee roaster led by founder Lin Tung-Yuan. Over nearly 20 years of experience and a decade of refinement, GABEE sourced green beans directly from top-tier estates and crafted these series to represent the full spectrum of specialty coffee flavors and cultural styles. This series isn’t just about variety—it’s about creating a sensory language for different coffee experiences.

1. Annual Memorial Recipe: Coffee That Recalls Moments

This concept transforms meaningful calendar dates into flavor experiences. By using creative bean blends and tailored roasting profiles, GABEE crafts annual memorial recipes that evoke specific emotions or events. The idea is to turn a memory into a sensory journey—where drinking the coffee brings you back to the feelings of a particular moment, showcasing coffee’s ability to express more than just caffeine.

2. Natural Process: Bold and Fruity

The natural process, the oldest method of coffee processing, involves drying whole coffee cherries under the sun. By keeping the fruit and pulp intact during drying, this method highlights intense, wild flavors. Expect a profile full of vibrant fruit tones, layered floral and fruity aromas, deep sweet notes, and rich fermented fruit characteristics. It’s a coffee that feels passionate and expressive, with a broad sensory range.

3. Northern Italian Espresso: Light, Bright, and Floral

Inspired by the elegant coffee culture of northern Italy (like Milan), this blend features carefully selected single-origin beans from Ethiopia, Kenya, Guatemala, and Colombia. Roasted to a medium-light level, it emphasizes the inherent qualities of each origin. The result is a clean, bright cup with distinct floral and fruity notes, subtle sweetness, and a cocoa finish—delivering the refined, delicate taste profile associated with northern Italian espresso bars.

4. Single-Origin Espresso: Complex Yet Balanced

Many coffee drinkers find single-origin beans too intense or unbalanced when brewed as espresso. GABEE addresses this by using a specialized roast profile suited for single-origin espresso. They select micro-lots from individual farms and estates, then roast to highlight each bean’s unique origin traits. The outcome is a rich, multi-layered espresso that showcases the distinct character of each single-origin coffee without overwhelming the palate.

5. Washed Process: Clean and Crisp

The washed process (or wet process) is designed to produce clean, stable coffee flavors through a meticulous method. Ripe cherries are washed, pulped, and then fermented to remove the mucilage before drying. This careful processing highlights clarity and balance. The resulting cup offers bright, clean acidity, delicate fruit notes, and a smooth, lingering sweetness—delivering a stable, refined flavor profile that’s easy to appreciate.

6. Southern Italian Espresso: Bold, Nutty, and Chocolatey

Modeled after the rich, bold coffee culture of southern Italy, this blend uses beans from Guatemala, Colombia, El Salvador, India, and Yunnan. Roasted to a medium-dark level, it delivers a full-bodied cup with layered complexity. Expect a silky mouthfeel reminiscent of maple syrup, along with deep notes of nuts, cream, and chocolate. The finish is long-lasting and satisfying, making it ideal for those who prefer a robust, traditional espresso experience.

7. Honey Process: Sweet and Smooth

The honey process combines elements of both washed and natural methods. After washing the cherries, some or all of the fruit skin is removed, but the sticky mucilage remains during drying. This controlled process enhances the coffee’s natural sugars. The result is a cup with pronounced sweetness, mild fermented fruit notes, and a rich, multi-dimensional finish. It delivers a warm, comforting sensation, often described as sweet and uplifting.

How to Use These Concepts in Brewing

While the article doesn’t provide specific brewing instructions for each series, the concepts align with common specialty practices. For espresso-based drinks like lattes, GABEE’s recommended parameters (from related FrontStreet material) include: 20g coffee to 40g espresso in 25–30 seconds, aiming for a 3mm crema layer. Milk should be textured to 60% full, heated to 55–60°C, and poured to achieve a ‘golden ring’ (even crema-milk blend). These guidelines help maximize the intended flavor profiles of each coffee in the series.
