The Art of Coffee Blending at Manta Ray Coffee Roasters: 

Elevating Flat White and Latte Experiences

In the heart of Melbourne's coffee culture, Manta Ray Coffee Roasters has earned its reputation for exceptional coffee blending craftsmanship. Our meticulously crafted coffee blends aren't just a technique—they're an art form that unlocks the unique qualities of each bean, elevating classic beverages like Flat White and Latte to new heights. This article explores how our blending philosophy enhances the flavour profiles and layers of these two iconic drinks, showcasing the artistry behind every cup.

Our Blending Philosophy: Purposeful Artistry

At Manta Ray Coffee Roasters, we live by the mantra of "exceptional quality and personalised experience." As a boutique roastery, we meticulously select premium beans from around the globe and create harmonious blends with diverse flavour profiles. Our approach is guided by two key principles:

Complementary Flavours

We pair beans with contrasting characteristics to create balanced and complex flavour profiles. For example, Ethiopian beans bring vibrant fruitiness, while Brazilian beans add rich nuttiness and body. This ensures that no single note dominates the cup, creating a harmonious drinking experience.

Defined Structure

Every blend has a clear hierarchy of flavours, with a 'lead' bean providing the primary profile and supporting beans adding depth and nuance. For instance, a Flat White blend might feature Ethiopian Yirgacheffe as the hero for its bright floral notes, complemented by Guatemalan beans for smooth chocolatey undertones.

Our Signature Blends: 

Composition and Character

The Outsider Blend

Our classic signature blend features a carefully calibrated mix of four distinct origins:

• 30% Guatemala Atitlan (washed): Provides chocolate notes and a structured backbone
• 20% Ethiopia Sidamo (washed): Contributes delicate citrus acidity and tea-like body
• 30% Ethiopia Yirgacheffe (natural): Delivers vibrant berry notes and floral aromatics
• 20% Brazil Blue Diamond (natural): Adds nutty sweetness and creamy mouthfeel

The combination of washed and natural processed beans creates a multi-dimensional experience that balances brightness with depth. The higher percentage of Ethiopian beans ensures vibrant top notes, while the Guatemala and Brazil components provide stability and sweetness.

The Stranger Blend

Our more adventurous blend features an even split of two exceptional specialty coffees:

• 50% Ethiopia Worka Sakaro Grade 1 (Carbonic Maceration): Introduces intense fruit-forward flavours with wine-like complexity
• 50% Rwanda Horizon Supreme Grade 1 (Natural): Contributes rich dark fruit notes and a syrupy body

This blend showcases experimental processing methods—with carbonic maceration bringing fermented fruit complexity typically found in natural wines. The result is a bold, complex profile that pushes boundaries while maintaining approachability.

Building Layers in a Flat White

The Essentials of Flat White Crafting

The Flat White is all about balance between coffee and milk, offering a seamless fusion that highlights the coffee's character without overpowering it. At Manta Ray, we refine this classic formula with innovative techniques:

1. Optimised Espresso Extraction

We use double shots or even Ristretto (short extractions) to intensify the coffee's flavour profile. The Outsider Blend, with its balance of fruity Ethiopian and structured Guatemalan components, creates a complex base that stands up beautifully to milk.

2. Mastering Microfoam Milk

The hallmark of a Flat White is its silky microfoam layer that blends perfectly with espresso without diluting its intensity.

Tasting Notes: The Outsider in Flat White

When prepared as a Flat White, The Outsider Blend reveals:

• Bright Front Notes: The Ethiopian Yirgacheffe (30%) and Sidamo (20%) combine to deliver blueberry, jasmine and citrus highlights that cut through milk.
• Rich Mid-Palate: Guatemala Atitlan (30%) provides chocolatey depth and caramel sweetness.
• Sweet Finish: Brazil Blue Diamond (20%) contributes a hazelnut-like sweetness and creamy mouthfeel.

The precise ratio ensures that no single origin dominates—instead, each component plays its designated role in the flavour journey.

Tasting Notes: The Stranger in Flat White

For those seeking a more adventurous Flat White experience, The Stranger Blend offers:

• Complex Fruit Profile: The Ethiopian Worka Sakaro's carbonic maceration process creates vibrant strawberry and tropical fruit notes that remain distinct even with milk.
• Structured Backbone: Rwanda Horizon's natural processing adds fig-like sweetness and rich body that supports the blend's wilder characteristics.
• Lingering Finish: The interplay between the two origins creates an evolving aftertaste that shifts from bright fruit to dark chocolate.

The equal proportion (50/50) creates tension between the experimental Ethiopian component and the more structured Rwandan beans, resulting in a dynamic Flat White experience.

Latte: A Celebration of Milk's Harmony

Crafting Latte Perfection

In contrast to the Flat White, Latte emphasises milk-forward smoothness, making it an ideal choice for those who prefer a gentler coffee experience. Our Latte preparation focuses on highlighting different aspects of our blends:

1. Adjusted Milk Ratio

With a higher milk-to-coffee ratio, we use full-fat milk to enhance creaminess while balancing acidity, allowing the cocoa notes in The Outsider and the dark fruit flavours in The Stranger to shine through.

2. Frothy Foam Layer

Unlike the silky microfoam in Flat White, Latte features a thicker foam layer that adds texture contrast while retaining its lightness.

The Outsider Blend in Latte Form

In a Latte, The Outsider Blend transforms to emphasise:

• Chocolate Prominence: The Guatemala Atitlan (30%) and Brazil Blue Diamond (20%) components become more pronounced, creating a milk chocolate and hazelnut character.
• Subtle Fruit Accents: The Ethiopian components (50% combined) provide delicate berry and floral notes that weave through the creamy texture.
• Rounded Mouthfeel: The careful balance of washed and natural processed beans creates a smooth, satisfying texture.

The Stranger Blend as a Specialty Latte

When The Stranger Blend meets the creamier Latte format:

• Berry Compote Character: The Ethiopian Worka Sakaro's experimental processing creates a jammy sweetness reminiscent of berry compote.
• Malty Undertones: Rwanda Horizon's natural processing contributes malt-like sweetness that pairs beautifully with steamed milk.
• Wine-like Complexity: Despite the higher milk content, the carbonic maceration processing retains its distinctive wine-like complexity.

How to Experience Layered Flavours

Key Dimensions for Tasting

According to SCA standards, coffee tasting involves evaluating:

• Aroma: The interplay between dry fragrance and wet aroma.
• Acidity: The sharpness or brightness contributed by fruity notes.
• Sweetness: Both natural bean sweetness and caramelisation from milk.
• Body: The tactile richness felt in your mouth.
• Flavour: Specific notes like berries, nuts, or chocolate.

Practical Tasting Tips

To fully appreciate Manta Ray's blends in Flat White or Latte:

• First Sip: Quickly assess overall balance—does the coffee shine through without being overshadowed by milk?
• Second Sip: Slowly savour individual layers—with The Outsider, look for the progression from Ethiopian brightness to Guatemalan structure; with The Stranger, notice how the carbonic maceration creates fermented fruit notes.
• Finish: Observe lingering flavours—The Outsider typically finishes with nutty sweetness, while The Stranger leaves a more complex, wine-like aftertaste.
