Cold brew coffee is a refreshing, smooth, and versatile drink that’s surprisingly easy to make at home using a French press. If you already own a French press for hot coffee, you’re just steps away from crafting your own cold brew.
This guide walks you through the process, from selecting the right beans to serving the perfect cup, ensuring you have everything you need for a delicious result. Optimized for coffee lovers searching for an at-home cold brew recipe, this post is your go-to resource for mastering cold brew with a French press.
What Is Cold Brew Coffee?
Cold brew coffee is made by steeping coarsely ground coffee in room-temperature water for an extended period, typically 12–24 hours. Unlike iced coffee, which is brewed hot and cooled, cold brew never touches heat, resulting in a smoother, less acidic flavor. The “cold” in cold brew refers to its chilled serving temperature, often over ice or straight from the fridge. Using a French press simplifies the process, as it doubles as both a brewing and filtering tool, making it ideal for home coffee enthusiasts.
Why Use a French Press for Cold Brew?
A French press is a fantastic tool for cold brew because it streamlines the process. The built-in plunger separates the coffee grounds from the liquid, eliminating the need for additional filters or equipment. If you already own a French press, you’re ready to start brewing without investing in specialized cold brew makers, which can range from $10 to over $100 on Amazon. For those who make cold brew occasionally, a French press is a practical, budget-friendly choice.
Equipment and Ingredients You’ll Need
To make cold brew coffee with a French press, gather these essentials:
- French Press: A standard 34-ounce French press works well for this recipe.
- Fresh Roasted Coffee Beans: Opt for light to medium roasts for nuanced flavors or dark roasts for bold richness. Aim for a 1:7 coffee-to-water ratio.
- Burr Grinder: A coarse grind, similar to kosher salt, ensures even extraction and prevents bitterness.
- Scale: Precision is key for the perfect coffee-to-water ratio.
- Room-Temperature Water: Use filtered water (70–80°F) if your tap water isn’t great. Avoid distilled water, as it lacks minerals that enhance flavor.
- Airtight Container: A mason jar or decanter stores your cold brew concentrate in the fridge.
Step-by-Step Guide to Making Cold Brew Coffee
Follow these simple steps to create a smooth, flavorful cold brew at home. The process takes about 15 minutes of active time, plus 12–24 hours of steeping.
Step 1: Weigh and Grind Your Coffee
Measure 50 grams of fresh coffee beans using a scale. Grind them to a coarse consistency, resembling kosher salt. A burr grinder ensures uniformity, preventing over-extraction that can make your cold brew bitter.
Step 2: Add Coffee to the French Press
Place the coarsely ground coffee into the bottom of your clean French press. Ensure the press is free of old coffee oils by rinsing it thoroughly before use.
Step 3: Pour in Room-Temperature Water
Weigh 350 grams of room-temperature filtered water. Slowly pour it over the coffee grounds, stirring gently with a spoon to ensure all grounds are fully saturated. This promotes even brewing and maximizes flavor.
Step 4: Cover and Steep
Place the lid on the French press but do not press the plunger down. Let the mixture steep at room temperature, away from direct sunlight or heat, for 12–24 hours. A 16-hour steep is a great starting point for balanced flavor—shorter steeps yield milder coffee, while longer ones produce a bolder concentrate.
Step 5: Plunge and Filter
After steeping, slowly press the plunger down using steady pressure to separate the grounds from the liquid. The French press’s mesh filter ensures a clean, sediment-free cold brew.
Step 6: Store and Refrigerate
Pour the cold brew concentrate into an airtight container, such as a mason jar, to prevent further extraction from residual grounds. Store it in the refrigerator, where it will stay fresh for up to two weeks. Avoid storing it in the French press, as this can lead to over-brewing.
| Cold Brew Recipe Summary | Details |
|---|---|
| Coffee Amount | 50 grams, coarsely ground |
| Water Amount | 350 grams, room temperature (filtered) |
| Coffee-to-Water Ratio | 1:7 |
| Steep Time | 12–24 hours (16 hours recommended) |
| Storage | Airtight container, refrigerate up to 2 weeks |
Serving Your Cold Brew Coffee
Cold brew concentrate is strong, so it’s typically diluted before drinking. Start with a 1:1 ratio of concentrate to water or ice, adjusting to taste (e.g., 1:2 or 1:3 for a lighter brew). Serve over ice for a refreshing drink or straight from the fridge for a chilled sip. To customize your cold brew, try these add-ins:
- Liquid Sweeteners: Simple syrup or agave nectar dissolves easily in cold liquids, unlike granulated sugar.
- Milk or Cream: Dairy or plant-based options add creaminess.
- Flavored Creamers: Vanilla, hazelnut, or seasonal flavors enhance the experience.
- Syrups: A drizzle of caramel or chocolate sauce elevates your drink.
For the best flavor, dilute only the portion you’re drinking and store the remaining concentrate undiluted. If you dilute a large batch, consume it within 2–3 days, as it loses freshness faster.
Benefits of Cold Brew Coffee
Cold brew’s unique brewing process yields distinct advantages. Because it’s steeped at room temperature, it’s less acidic than hot-brewed coffee, making it gentler on sensitive stomachs. The slow extraction also produces a smoother, sweeter flavor that highlights the coffee’s natural notes.
Cold brew concentrate can pack a stronger caffeine punch—potentially up to twice that of hot coffee—depending on the beans and dilution ratio. This makes it a great choice for an energizing boost. Additionally, cold brew shares coffee’s health benefits, such as antioxidants that may support heart health, boost metabolism, and promote longevity, according to Healthline. Like hot coffee, plain cold brew is low-calorie (e.g., 5 calories per 16-ounce serving), but add-ins like creamers or syrups can increase the count.
Tips for Success
- Experiment with Steep Time: Adjust between 12 and 24 hours to find your preferred strength.
- Clean Your French Press: Rinse thoroughly after each use to remove coffee oils that can affect future brews.
- Batch Prep: Double the recipe for a week’s worth of cold brew, storing it as a concentrate.
- Taste Test: Try different roasts or origins to discover your favorite cold brew profile.
