Discover how to use ultra-filtered milk in cold brew coffee for creamy, high-protein iced coffee recipes perfect for summer. Learn tips, ratios, and flavor variations.

When summer heat hits, nothing beats a tall glass of cold brew coffee. But plain black cold brew can feel a bit… boring. Enter ultra-filtered milk — a game-changer for anyone who wants a creamy, protein-packed iced coffee without the extra sugar or calories. In this guide, we’ll explore how to use ultra-filtered milk in cold brew coffee, share easy high-protein iced coffee recipes, and show you why Fairlife’s lineup is the perfect partner for your summer caffeine fix.

Why Ultra-Filtered Milk Works So Well in Cold Brew

Cold brew coffee is naturally less acidic and smoother than hot-brewed coffee, making it an ideal canvas for creamy additions. Ultra-filtered milk takes that smoothness to the next level because it’s concentrated — it has about 50% more protein and 30% less sugar than regular milk. That means you get a richer, silkier texture without watering down your coffee or adding unnecessary sweeteners. Plus, the higher protein content helps keep you full and focused through the afternoon slump.

Fairlife’s ultra-filtered milk comes in several varieties, each bringing a slightly different mouthfeel and nutritional profile to your cold brew. For a classic, indulgent experience, try WHOLE ULTRA-FILTERED MILK — its full-fat creaminess balances the bold notes of cold brew beautifully. If you’re watching calories but still want protein, FAT FREE ULTRA-FILTERED MILK delivers 13 grams of protein per cup with zero fat.

How to Make the Perfect High-Protein Cold Brew Latte

Making a cold brew latte with ultra-filtered milk is incredibly simple. Start with a strong cold brew concentrate (store-bought or homemade). The key ratio is 1 part milk to 2 parts concentrate for a balanced, not-too-milky drink. Here’s a step-by-step recipe:

  • Brew your cold brew: Combine 1 cup coarsely ground coffee with 4 cups cold water. Steep for 12-24 hours in the fridge, then strain through a fine-mesh sieve or cheesecloth.
  • Chill your milk: Ultra-filtered milk is best when ice-cold. Keep a carton in the fridge.
  • Assemble: Fill a glass with ice. Pour 1/2 cup cold brew concentrate, then add 1/4 cup ultra-filtered milk. Stir gently.
  • Optional boost: Add a splash of vanilla extract or a pinch of cinnamon for extra flavor without sugar.

This simple base can be customized endlessly. For a sweeter twist, use Fairlife’s CHOCOLATE ULTRA-FILTERED MILK instead of plain — it turns your coffee into a mocha-like treat with 13 grams of protein per serving.

Three High-Protein Iced Coffee Recipes Using Fairlife Milk

Ready to get creative? Here are three recipes that showcase the versatility of ultra-filtered milk in cold brew coffee.

1. Classic Cold Brew Latte (with a protein twist)

This is your go-to morning drink. Combine 1 cup cold brew concentrate, 1/2 cup of 2% Reduced Fat Ultra-Filtered Milk, and ice. The 2% version offers a perfect middle ground — creamy but not heavy, with 13g protein per cup. For a subtle sweetness, add a dash of honey or a sugar-free vanilla syrup.

2. Mocha Protein Cold Brew

Craving a chocolate fix? Use CHOCOLATE ULTRA-FILTERED MILK as your base. Mix 1 cup cold brew concentrate with 1/2 cup chocolate ultra-filtered milk. Stir in 1 tablespoon unsweetened cocoa powder for extra richness. Top with a sprinkle of sea salt — the salt enhances the chocolate and coffee flavors beautifully. Each serving delivers about 20g of protein.

3. Strawberry Cold Brew Creamsicle

This one sounds wild but tastes incredible. Blend 1 cup cold brew concentrate with 1/2 cup STRAWBERRY FAT 14oz ultra-filtered milk and a handful of ice until smooth. The strawberry flavor pairs surprisingly well with the coffee’s bitterness, creating a creamy, refreshing drink that’s like a grown-up ice cream float. It’s perfect for hot afternoons.

Tips for the Best Ultra-Filtered Milk Cold Brew Experience

  • Shake, don’t stir: For a frothier texture, pour your milk and cold brew into a sealed jar and shake vigorously for 10 seconds before pouring over ice.
  • Adjust sweetness: Ultra-filtered milk is naturally lower in sugar than regular milk, so your coffee may taste less sweet. Add a zero-calorie sweetener like stevia or a splash of vanilla syrup if desired.
  • Use a milk frother: If you have a handheld frother, froth the ultra-filtered milk before adding it to the cold brew. It creates a beautiful microfoam that mimics a hot latte texture.
  • Make it a meal: For an extra protein boost, blend your cold brew and milk with a scoop of vanilla protein powder or a serving of Fairlife’s CORE POWERC HOCOLATE shake. This turns your iced coffee into a post-workout recovery drink.

Nutritional Comparison: Ultra-Filtered Milk vs. Regular Milk in Coffee

Milk Type (1 cup) Protein Sugar Calories Calcium
Whole ultra-filtered milk 13g 6g 150 40% DV
Fat-free ultra-filtered milk 13g 6g 90 40% DV
Regular whole milk 8g 12g 150 30% DV
Regular skim milk 8g 12g 80 30% DV

As the table shows, ultra-filtered milk packs nearly 60% more protein and half the sugar of regular milk — a huge win for anyone watching their macros or blood sugar.

Why Fairlife Ultra-Filtered Milk Is the Best Choice for Coffee Lovers

Fairlife’s ultra-filtered milk is made using a patented cold-filtration process that concentrates protein and calcium while removing lactose and excess sugar. This means it won’t curdle or separate when mixed with cold brew, unlike some plant-based milks. Plus, it has a clean, mild flavor that lets the coffee shine — no weird aftertastes. Whether you choose whole, 2%, fat-free, or chocolate, each variety integrates seamlessly into iced coffee drinks.

For those who want even more protein without extra volume, Fairlife’s Core Power shakes (like CORE POWERC HOCOLATE) are also excellent in cold brew. Use them as a ready-to-pour milk substitute for a 26g protein iced latte.
