Best Coffee Beans for Cold Brew: Quick Comparison
The best coffee beans for cold brew are medium to dark roasts with chocolatey, nutty, or caramel flavor notes, ground coarse and steeped 12 to 18 hours. At Chilled Iguana Coffee Co., we built our whole lineup around that idea: slow-steeped coffee should taste smooth, sweet, and low-acid, never sharp or bitter. Below, we break down grind size, coffee to water ratio, steeping time, and which of our roasts fits your glass.
| Coffee | Roast | Flavor Notes | Best For | Price |
|---|---|---|---|---|
| Cold Brew Coffee | Medium | Chocolate, toffee, floral | Dedicated cold brew & nitro | $16.99 |
| Cowboy Blend | Dark & Medium | Cocoa, caramel, vanilla | Everyday cold brew | $16.99 |
| 6 Bean Blend | Dark | Chocolate, caramel, cocoa | Bold, strong concentrate | $16.99 |
| Best Sellers Sample Pack | Mixed | Six distinct profiles | Finding your favorite | $22.99 |
Cold Brew Coffee Grind Size and Coffee to Water Ratio for Cold Brew
The right cold brew coffee grind size is coarse, roughly the texture of sea salt, and the standard coffee to water ratio for cold brew is 1:4 to 1:5 by weight for a concentrate you dilute later. Too fine and you get mud and bitterness. Too coarse and the water never pulls the sweetness out.
For a 1:4 ratio, that means 1 cup of coarsely ground coffee to 4 cups of cold, filtered water. Stir once to saturate the grounds, then leave them alone.
Cold Brew Steeping Time and Roast Selection
Cold brew steeping time runs 12 to 18 hours at room temperature or up to 24 hours in the fridge, and medium to dark roasts hold up best over that long soak. Lighter roasts can taste thin and sour after a full day of steeping, while darker beans keep their chocolatey, caramel sweetness.
That is why we point most people toward our Cold Brew Coffee, a medium roast with chocolate, toffee, and floral tones built for cold extraction. If you want something bolder, the 6 Bean Blend brings dark chocolate and low acidity. Not sure where to start? The Best Sellers Sample Pack lets you taste six roasts and pick your winner.
Store your concentrate airtight in the fridge and it keeps for several days. Serve over ice in a can-shaped glass for that full vacation feel.
Frequently Asked Questions
What grind of beans is best for cold brew?
Coarse grind is the standard for cold brew. It looks like raw sugar or sea salt and keeps the steep clean. A coarse grind slows extraction during the long steep, so you get sweetness and body without the bitterness that fine particles release. If your grinder can't go coarse, pulse in short bursts and sift out the dust before steeping.
Does roast level matter for cold brew coffee?
Yes. Medium and medium-dark roasts are the sweet spot for cold extraction. They carry chocolatey, nutty, and caramel flavor notes that hold up over a 12 to 18 hour steep. Dark roasts can turn ashy if you push the time too long, and light roasts often taste thin and sour because cold water pulls less acidity and sugar from them.
What is the ideal coffee to water ratio for cold brew?
Start with a 1:5 ratio by weight for concentrate, so 1 cup of coarse grounds to 5 cups of cold filtered water. Dilute the finished concentrate 1:1 with water or milk before serving. If you prefer ready-to-drink cold brew, brew at 1:15 and skip the dilution step. Adjust by taste after your first batch.
Finding beans that stay sweet through a long steep is the whole game, and that is exactly what we roast for. Get started with Chilled Iguana Coffee Co. and let our Cold Brew Coffee, Cowboy Blend, and Best Sellers Sample Pack bring a little laid-back island ease to your daily cup.
