Light Roast vs. Medium Roast Cold Brew: Which One Is Better?

Cold brew season brings up one of the most debated questions in coffee: light roast or medium roast? The honest answer is that both roasts make an incredible cold brew — they just get you there in different ways. If you love a bright, delicate iced coffee, light roast is going to be your best friend. If you want something rounder, sweeter, and endlessly customizable with flavor, medium roast is where it's at. Let's break down what actually separates the two, and then get into why our medium roast lineup gives you more flavor options than almost anywhere else.

What Makes a Roast "Light" or "Medium" in the First Place?

Roast level comes down to how long and how hot the beans are roasted, and it changes everything about the bean's chemistry. Light roast beans are typically pulled around the 440°F range, while medium roast beans are carried further, up to around 465°F. That extra time and heat is what separates the two. Because light roast beans are pulled earlier, they hold onto more of their original moisture and density, producing a delicate brew that's light in body with no surface oil, and a flavor that leans toasty with brighter acidity that lets the bean's original character shine through.

Medium roast beans are taken a bit further, carried up to that higher 465°F range. Medium roast beans develop a rich brown color and a non-oily surface — this roasting level preserves some of the bean's original characteristics while adding the deeper flavors that develop with more time over heat. The result strikes a perfect balance between the bright acidity of light roasts and the deep, robust flavors of dark roasts, which is exactly why medium roast has become the most popular roast level for everyday drinking.

Light Roast Cold Brew: Bright, Clean, and Nuanced

If you're after a cold brew that tastes like the bean itself, light roast is the way to go. The delicate roasting process highlights the beans' subtle nuances, letting you experience an array of floral, fruity, and herbal notes that simply don't survive a longer roast. Because light roast beans hold onto more of their origin character, a light roast cold brew tends to taste cleaner and more complex, almost tea-like, with the bean's natural acidity front and center.

The tradeoff is that light roasts ask more of your brewing process. Since they haven't developed the deep caramelized sugars that a medium or dark roast has, the flavor is more delicate and can get lost over a long steep if you're not using enough grounds. But when it's dialed in, a light roast cold brew is one of the most rewarding, nuanced iced coffees you can make at home.

Medium Roast Cold Brew: Balanced, Smooth, and Endlessly Flavorable

Medium roast is the reason so many people default to it for cold brew, and for good reason. Medium roasts are highly versatile, excelling in drip brewers, pour-overs, or even cold brews, and these crowd-pleasing coffees are also great for pairing with milk and sugar. The extended steep time of cold brewing draws out natural sweetness, and a medium roast has just enough developed sugar and body to come through smooth and rounded rather than sharp.

It's also simply more forgiving. Medium roast beans have a fuller body and a more balanced acidity than light roast, so there's more room for error in your grind size or steep time before the flavor falls flat. That balance is also exactly why medium roast is the roast level we use for every single one of our flavored coffees — it's rich enough to stand up to a flavor and light enough to let that flavor actually shine, rather than fight with heavy roast bitterness.

Why We Only Flavor Our Medium Roasts

Here's the thing about flavored cold brew: it only works if the base coffee is doing its job. These beans grow at high altitudes, developing dense, complex flavor profiles naturally, and our roastmasters carefully roast these premium beans to a precise medium profile. A medium roast preserves the natural sweetness and smooth finish of the Arabica bean without introducing the smoky bitterness of a dark roast, which means the flavoring blends in instead of covering anything up. When we add flavorings, they blend seamlessly with the coffee's natural oils, and because we start with Specialty Class 1 Arabica beans — the top 2% of coffee grown in the world — the flavor never has to work overtime to mask a lower-quality bean.

That's exactly what makes our medium roast flavored coffees such a natural fit for cold brew. A few standout options to try iced this season:

• Cherry Creme — sweet Door County cherries and creamy vanilla, brewed cold for a fruity, refreshing glass.
• Turtles in a Cup — chocolate, caramel, and nutty notes that turn your cold brew into dessert.
• Hawaiian Hazelnut — a warm, toasted hazelnut flavor that mellows out beautifully over a cold steep.
• Heavenly Caramel — smooth caramel sweetness that pairs perfectly with milk or oat milk over ice.
• Chocolate Raspberry Truffle — rich cocoa and bright raspberry, a dessert-in-a-glass cold brew option.

Every one of these starts as a medium roast Specialty Class 1 Arabica bean before any flavoring ever touches it, so what you're tasting in the glass is real flavor layered onto a genuinely great coffee — not flavor doing damage control on a mediocre one.

So, Which Roast Is Actually Better for Cold Brew?

Honestly, there's no wrong answer — both roasts make a fantastic cold brew, and it comes down to what you're craving. Reach for a light roast when you want something bright, nuanced, and true to the bean's origin. Reach for a medium roast when you want a smooth, well-rounded cold brew, especially if you're leaning into one of our flavored coffees. If you can't decide, that's the best excuse to brew a batch of each and taste the difference for yourself — that's half the fun of cold brew season anyway.

Whichever roast you land on, it all comes back to the same foundation: Specialty Class 1 Arabica beans, carefully roasted, and ready to make your next glass of iced coffee the best one yet.
