Cold brew is the most forgiving way to make coffee — and the choice of beans is what separates a flat, watery batch from a smooth, chocolatey one you'll want all summer. Here's exactly what to look for in the roast, the grind, and the origin, plus the ratio that gets it right.

Cold water extracts differently than hot. It pulls out sugars and body readily but leaves behind much of the bright, acidic, aromatic compounds that hot brewing captures. That's why cold brew tastes so smooth and low-acid — and it's also why roast choice matters more here than almost anywhere else.
A medium-to-dark roast is the classic cold brew answer. The chocolate, caramel, and toasted-nut flavors that develop with a longer roast come through rich and sweet in cold water, with almost none of the sharpness. This is the bold, smooth, "iced coffee shop" profile most people are chasing when they make cold brew.
A light roast can make genuinely lovely cold brew too — cleaner, more delicate, closer to iced tea, showing off fruit and florals. It's just a different, subtler drink. If you love bright, fruity coffee, try it. If you want bold and chocolatey, go darker.
Start with a medium or dark roast for your first cold brew. It's the most forgiving and the most crowd-pleasing. Branch into lighter roasts once you know what you like.
Once you've picked a roast level, origin fine-tunes the flavor. The heavy hitters for cold brew:
If you like fruit-forward coffee, an African single origin (Ethiopia, Kenya) makes a bright, berry-ish cold brew — delicious, just not the classic smooth style.
Use a coarse grind, like raw sugar or coarse sea salt. Cold brew steeps for 12–24 hours, and a fine grind over that long a time over-extracts into bitterness and makes filtering a chore. Even, coarse particles are the goal — which means a burr grinder, not a blade one. A blade grinder produces dust and boulders together, and the dust turns a long steep muddy and bitter. See our grinder guide for the coarse, even grind cold brew wants.
And freshness still counts. The long steep hides some staleness, so cold brew is more forgiving than espresso — but fresh, whole beans ground just before brewing still make a noticeably rounder, sweeter batch than months-old pre-ground. This is the whole reason we roast to order: fresh beans are the input everything else depends on.
Cold brew is refreshingly simple:
The gear side of this — which steeper actually makes it easy — is covered in our cold brew makers guide.
Put it together: look for a medium or dark roast, a roast date on the bag (not a "best by"), whole beans you'll grind coarse, and origin notes like chocolate, nut, caramel, or "cold brew blend." A grocery-store bag labeled for cold brew will do in a pinch, but it's usually old — and cold brew rewards fresh beans more than people expect.
That's exactly the coffee we make: fresh-roasted to order, chocolatey medium and dark options, with the roast date on every bag. If you want a cold brew that tastes like the good iced coffee shop instead of the sad office pitcher, start here.
A medium-to-dark roast with chocolate, nut, or caramel notes — a Brazil, Sumatra, Colombian, or a blend built for it. Cold brew's low acidity flatters heavier flavors. Use fresh whole beans and grind coarse just before brewing.
Medium to dark for the classic bold, smooth, low-acid profile. Light roasts make a cleaner, more delicate, tea-like cold brew that highlights fruit — great, just a different drink.
Coarse, like raw sugar. The long steep over-extracts a fine grind into bitterness; coarse, even particles from a burr grinder keep it smooth and easy to filter.
About 1 part coffee to 4–5 parts water for concentrate, or 1 to 8 for ready-to-drink. Steep 12–18 hours at room temp (up to 24 in the fridge), then filter.
