Best Coffee for Cold Brew — Smooth, Low Acid, and Worth the Wait
Cold brew is the most forgiving brew method you can make at home: coarse grind, cold water, twelve hours, done. But forgiving does not mean the coffee choice does not matter. In fact, because cold brew is served concentrated and often over ice, the flavor characteristics of the bean come through more clearly than in almost any other format.
This guide covers everything you need to choose the best coffee for cold brew: which roast levels work best, why grind size matters, and which specific coffees from our lineup are built for cold extraction. We will also address the great cold brew debate, medium-light versus medium-dark, because the answer is not the same for everyone.
What Makes a Coffee Good for Cold Brew?
Cold brew extracts coffee slowly over twelve to twenty-four hours using cold or room temperature water instead of heat. The slow, cold extraction pulls out sweetness, chocolate, and low-acid flavors while leaving behind many of the harsh, bitter, and high-acid compounds that hot water extracts quickly. The result is a naturally smooth, sweet, and low-acid cup that tastes nothing like iced coffee made from hot brew poured over ice.
The best cold brew coffees share three characteristics:
Best Roast Levels for Cold Brew
This is where cold brew gets interesting, and where personal preference genuinely matters. Unlike espresso or French press, there is no single correct answer for cold brew roast level. The right choice depends on what kind of cold brew experience you are looking for.
Our Cold Brew Picks and Who They Are For
We get asked regularly whether to use Backroad Cold Brew or Rogue Traveler for cold brew. The honest answer is that it depends on your taste preferences, and both are excellent choices for different reasons.
Which one should you choose?
Choose Backroad Cold Brew if you want a cleaner, more nuanced cold brew with chocolate and toffee notes and a lighter body. It is purpose-roasted for cold extraction and produces a cold brew that is smooth, complex, and distinctly different from your typical grocery store cold brew concentrate.
Choose Rogue Traveler if you want a bolder, richer cold brew with more body and a darker chocolate and caramel profile. This is Jamie's personal cold brew choice and the one we reach for when we want something that drinks more like a traditional cold brew concentrate — bold enough to stand up to milk or oat milk without getting lost.

Grind Size and Ratio for Cold Brew
Cold brew is forgiving about most variables, but not about grind size. Get the grind right and everything else falls into place. Get it wrong and no amount of steeping time will fix the cup.
The cold brew grind and ratio rule
Grind: Extra coarse, even coarser than French press. Think rough breadcrumbs or the texture of raw sugar. The long steep time compensates for the reduced solubility of cold water. A fine grind in cold brew produces a bitter, over-extracted concentrate that tastes nothing like good cold brew.
Ratio: 1:4 for cold brew concentrate, one part coffee to four parts water by weight. This produces a concentrate you dilute to taste, typically 1:1 with water or milk. For ready-to-drink cold brew, use a 1:8 ratio and drink it straight over ice.
Example: For a standard mason jar cold brew concentrate, use 100g of coarsely ground coffee to 400ml of cold filtered water. Steep 12 to 24 hours in the refrigerator. Dilute 1:1 when serving.
| Format | Ratio | Steep Time | How to Serve |
|---|---|---|---|
| Concentrate | 1:4 coffee to water | 12 to 24 hours | Dilute 1:1 with water or milk over ice |
| Ready to drink | 1:8 coffee to water | 12 to 18 hours | Serve straight over ice — no dilution needed |
| Cold brew cocktail | 1:4 concentrate | 12 to 24 hours | Mix with spirits, simple syrup, and ice |
Cold Brew Method — Step by Step
Cold brew is one of the easiest coffee methods you can make at home. Here is the process from start to finish:
- Grind coarsely. Use an extra coarse grind, much coarser than French press. If you are ordering pre-ground, select cold brew as your grind preference at checkout, and we will grind it correctly.
- Combine coffee and cold water. Add your coffee to a mason jar, French press, or dedicated cold brew maker. Pour cold filtered water over the grounds at your chosen ratio. Stir gently to make sure all the grounds are saturated.
- Cover and refrigerate. Cover loosely and place in the refrigerator. Steep for 12 to 24 hours. Twelve hours produces a lighter, brighter cold brew. Twenty-four hours produces a darker, bolder concentrate.
- Filter and store. Pour the cold brew through a fine mesh strainer lined with a paper filter or cheesecloth to remove the grounds. Store the filtered concentrate in a sealed container in the refrigerator for up to two weeks.
- Serve over ice. Dilute concentrate 1:1 with cold water or milk. Add ice. Drink immediately or store for up to a week.
The cold brew patience payoff
The hardest part of cold brew is waiting twelve hours. Make a batch the night before you need it, and it will be ready by morning. Make a double batch on Sunday and you have cold brew for the entire week. The actual hands-on time is about five minutes. Everything else is the refrigerator doing the work for you.
Cold Brew Equipment
You do not need specialized equipment to make excellent cold brew at home. A mason jar and a fine mesh strainer will get the job done. That said, dedicated cold brew makers make the process cleaner and easier, especially the filtering step, which can be messy without the right setup.

The minimum viable cold brew setup
A 32oz wide-mouth mason jar, a fine mesh strainer, and a paper coffee filter. That is all you need to make excellent cold brew at home. The mason jar holds your steep. The strainer catches most of the grounds. The paper filter catches the fine particles. The total cost is under five dollars if you do not already have these. No excuse not to try it this week.
Cold Brew FAQs
What is the difference between Backroad Cold Brew and Rogue Traveler for cold brew?
Backroad Cold Brew is a medium-light roast purpose-built for cold extraction, clean, nuanced, with chocolate and toffee notes, and a lighter body. Rogue Traveler is a medium-dark roast that produces a bolder, richer cold brew with more chocolate and caramel character. Backroad is the choice if you want something lighter and more complex. Rogue Traveler is the choice if you want something darker and bolder — it is Jamie's personal cold brew preference.
How long should I steep cold brew?
12 to 24 hours in the refrigerator is the standard range. Twelve hours produces a lighter, brighter cold brew with more nuance. Twenty-four hours produces a darker, more concentrated cold brew with more body. Start at twelve hours and adjust based on your taste preference. Steeping longer than 24 hours can produce bitter, over-extracted cold brew.
What grind size should I use for cold brew?
Extra coarse — significantly coarser than French press, much coarser than drip. The long steep time compensates for the lower extraction rate of cold water. Fine grinds in cold brew produce bitter, over-extracted concentrate. When ordering pre-ground coffee for cold brew from us, select cold brew as your grind preference, and we will grind it correctly at checkout.
Can I make cold brew with any coffee?
Yes, but the results vary significantly. Medium and medium-dark roasts produce the smoothest, most naturally sweet cold brew. Light roasts tend to produce thin, slightly sour cold brew that does not extract well in cold water. Dark roasts work well but require a very coarse grind and a shorter steep to avoid bitterness.
How long does cold brew last in the refrigerator?
Cold brew concentrate stored in a sealed container in the refrigerator lasts up to two weeks. Ready-to-drink cold brew lasts up to a week. The high coffee-to-water ratio of concentrate acts as a mild preservative. If your cold brew tastes flat or sour after several days, it is past its peak — make a fresh batch.
Should I use filtered water for cold brew?
Yes. Water quality matters more in cold brew than in hot brew methods because there is no heat to mask off-flavors. Chlorine and mineral content in tap water come through clearly in cold brew. Filtered water produces a noticeably cleaner, sweeter cup. If your tap water tastes good on its own, it will work fine. If it does not, filter it first.
