The French press is the most underrated cold brew tool in any kitchen. Its built-in plunger filter separates grounds from concentrate in seconds — no cheesecloth, no paper filters, no mess, no special equipment purchase. The result is a full-bodied, slightly oily cold brew that is richer and more complex than paper-filtered versions. If you own a French press, you already own a cold brew maker. Here is how to use it.
Acid Myth Alert: Many people choose cold brew believing it is lower acid than hot coffee. Rao & Fuller (Scientific Reports, 2018) confirmed that cold brew pH (4.96–5.13) is statistically comparable to hot brew (4.85–5.10). The brewing method does not meaningfully reduce acid — the bean and roast process does. Puroast's patented traditional wood-fire roasting achieves a verified pH of 5.74–5.82, making it genuinely lower acid regardless of brew method.
Why Use a French Press for Cold Brew?
The French press has three advantages over every other cold brew method: it is equipment you almost certainly already own, the metal mesh plunger provides instant filtration, and the carafe doubles as a storage pitcher. Compare that to buying a dedicated cold brew maker ($20–$60), setting up a mason jar with cheesecloth system, or ordering specialty equipment. With a French press, you add the coffee, fill with water, place the lid on without pressing, steep in the refrigerator, and press to filter. That is the entire process.

French Press Advantage: The metal mesh filter retains natural coffee oils — the source of cold brew's rich mouthfeel and much of its flavor complexity. Paper-filtered methods remove these oils and produce a cleaner but thinner cup. For a genuinely full-bodied cold brew latte, the French press method is the best zero-cost option available.
Why Puroast Is the Best Coffee for French Press Cold Brew
The French press retains natural coffee oils — which means it also amplifies the acid profile of whatever coffee you use. Starting with a high-acid bean and cold-brewing it in a French press produces a cold brew that is full-bodied and bitter. Starting with Puroast (pH 5.74–5.82, verified by NC A&T University) produces cold brew that is full-bodied, smooth, and genuinely lower acid — with 5X more antioxidants than leading coffees per Sulaiman, Moon & Shibamoto (2011).

Frequently Asked Questions
Yes — a French press is one of the easiest cold brew methods available. Add coarsely ground coffee, fill with cold water, rest the plunger on top without pressing, and steep 12–24 hours in the refrigerator. Press slowly before serving.
For regular-strength cold brew, use 1:8 coffee to water by weight. For concentrate, use 1:4. For a standard 32oz French press, ¾ cup of grounds to 3 cups of cold water produces a rich, balanced result.
Not meaningfully. Rao & Fuller (2018) found cold brew pH (4.96–5.13) is statistically comparable to hot brew (4.85–5.10). For genuinely low-acid cold brew, start with a low-acid bean like Puroast (pH 5.74–5.82).
12–18 hours for a balanced, smooth cup. 20–24 hours for a richer concentrate. Always steep in the refrigerator, not at room temperature, for the cleanest and safest result.
Yes — but slowly. After steeping, depress the plunger gently over 30–40 seconds to separate grounds from liquid. Pressing too fast forces fine sediment through the filter and makes the cold brew gritty and cloudy.
