BOB's BLOG - Inside the Cup Vol 5 - Milk Matters: Why Fresh Local Milk Makes Better Coffee - Friday 3 October 2025

Greetings T&T VIPS!

There's a quiet revolution happening in specialty coffee shops, and it starts not with the espresso machine, but with what we pour into the jug. While we obsess over bean origins, roast profiles, and extraction times, there's another ingredient that makes up the majority of your cappuccino or flat white: milk. And not all milk is created equal.

The Northiam Difference

Nestled in the heart of East Sussex, Northiam Dairies has been producing exceptional milk for over 60 years. This isn't your typical supermarket milk that's travelled hundreds of miles and been processed within an inch of its life. Northiam's dairy operation represents something increasingly rare: genuinely local, small-batch milk production that prioritises quality over volume.

The farm's Holstein-Friesian herd grazes on lush Sussex pastures, producing milk that reaches us within 24-48 hours of milking. This freshness isn't just a marketing point—it's something you can taste, smell, and see in every cup we serve.

Non-Homogenised: What It Means and Why It Matters

Here's where Northiam Dairies milk truly stands apart. Unlike the standardised milk lining supermarket shelves, this milk is non-homogenised. To understand why this matters for your coffee, we need a quick science lesson.

Homogenisation is an industrial process that forces milk through tiny nozzles at high pressure, breaking down fat globules into uniform microscopic particles. This prevents cream from separating and rising to the top, creating a consistent product with a long shelf life. It's efficient, predictable, and utterly transforms the milk's natural structure.

Non-homogenised milk, by contrast, retains its natural fat globule structure. You'll notice cream forming at the top of the bottle—that's not a defect, it's evidence of authenticity. These larger, intact fat molecules behave differently when heated and create a superior microfoam structure when steamed properly.

The result? A richer, more velvety texture in your latte, with a natural sweetness that doesn't require flavoured syrups. The milk's proteins and fats interact more harmoniously with coffee, enhancing rather than masking the espresso's complex flavours.

Handling Fresh, Local Milk

Fresh, non-homogenised milk demands respect. Here's how we handle it:

Storage is crucial. We maintain our milk between 1-4°C at all times and rotate stock rigorously. Fresh milk has a shorter shelf life than its ultra-processed counterparts, but that's the trade-off for superior quality.

Always shake before use. Because the cream naturally separates, giving the bottle a gentle shake ensures consistency. This isn't just about texture—it's about ensuring every cup receives the full spectrum of flavours that the milk offers.

Watch your dates. Fresh local milk is best used within 3-4 days of opening. The absence of ultra-high temperature processing means natural milk enzymes remain active, so freshness matters more than with conventional milk.

Steaming Tips for Baristas

Steaming non-homogenised milk requires a slightly different approach than working with homogenised alternatives:

Start with cold milk. Always begin with milk straight from the fridge (ideally 3-4°C). This gives you more time to develop the perfect microfoam before the milk reaches its ideal serving temperature of 60-65°C.

Introduce air early. In the first 3-5 seconds, position the steam wand just below the milk's surface to incorporate air. You'll hear a gentle "tss-tss" sound. The larger fat globules in non-homogenised milk create a more stable foam structure, so you may need slightly less aeration than with conventional milk.

The rolling phase is key. Once you've introduced sufficient air, submerge the wand deeper to create a whirlpool effect. This incorporates the foam throughout the milk, creating that glossy, wet paint texture we're after. Non-homogenised milk reaches this consistency beautifully when handled correctly.

Temperature matters. Stop steaming at 60-65°C. Beyond this, you'll scald the milk, destroying its natural sweetness and creating a thin, burnt flavour. Fresh milk's natural sugars caramelise beautifully at the right temperature, but punish you for overheating.

Latte Texture Basics

The holy grail of milk steaming is achieving microfoam—tiny, imperceptible bubbles that create a silky, glossy texture. Here's what you're aiming for:

Microfoam should be glossy and wet when you pour, with no visible bubbles. When you tap the jug on the counter, the surface should remain smooth and shiny, like wet paint. If you see large bubbles forming, you've over-aerated.

The "pour test" never lies. Properly steamed milk pours in a steady, controlled stream. It shouldn't gush out quickly (too thin) or plop out in chunks (over-aerated). It should ribbon from the jug, maintaining body and viscosity.

Texture integrates with espresso. The goal isn't just beautiful latte art—though that's a welcome bonus. Perfectly steamed milk should integrate seamlessly with espresso, creating a harmonious drink where each sip delivers balanced sweetness, velvety texture, and the coffee's distinctive character.

With non-homogenised milk from Northiam Dairies, the natural fat structure creates a more stable foam that holds its texture longer. Your flat white or cappuccino will maintain that silky consistency from first sip to last.

The Complete Coffee Experience

Great coffee is a sum of its parts: exceptional beans, skilled extraction, clean water, and—yes—the right milk. By choosing fresh, local, non-homogenised milk from Northiam Dairies, we're not just supporting local agriculture. We're recognising that quality ingredients matter at every stage.

The next time you order a cappuccino or flat white, take a moment to appreciate the milk. Notice its natural sweetness, its velvety texture, the way it complements rather than overwhelms the espresso. That's the Northiam difference, and it's why milk matters.
