TL;DR: To make cold brew coffee, steep coarsely ground beans in cold water for twelve hours using a ceramic or glass vessel. Strain the concentrate and dilute with water or milk to taste for a smooth, low-acidity beverage.
Why Porcelain Matters for Cold Brew
While many home brewers opt for plastic jars or metal filters, the choice of vessel significantly impacts the final flavor profile and the longevity of your brewing setup. Porcelain is an exceptional material for cold brew enthusiasts because it is non-porous and chemically inert. Unlike wood, which can absorb oils and develop stale flavors over time, or certain plastics that may leach unwanted tastes, porcelain provides a neutral canvas that allows the pure, nuanced notes of your coffee beans to shine through without interference. Furthermore, a high-quality porcelain carafe or steeping jar is durable, easy to clean, and aesthetically pleasing, making it a centerpiece for your kitchen counter or coffee station. When selecting a porcelain vessel, look for pieces with a smooth, glazed interior to ensure that coffee grounds do not stick to the walls, simplifying the cleanup process after your twelve-hour steep.

Gathering Your Tools and Ingredients
Before you begin, ensure you have the right equipment. A large, wide-mouthed porcelain jar with a tight-fitting lid is essential for optimal surface area exposure. You will also need a fine-mesh sieve, a paper filter for a second pass, a kitchen scale, a burr grinder, and fresh, filtered water. For the coffee, choose a light or medium roast with coarsely ground beans, resembling the texture of sea salt. The ratio is the most critical variable; a standard starting point is one cup of coarsely ground coffee for every four cups of water. This yields a concentrated brew that can be diluted later to suit your preference.
The Brewing Process
First, add your coarsely ground coffee to the bottom of your clean porcelain jar. Next, pour the filtered cold water over the grounds, ensuring that every piece of coffee is fully saturated. Use a wooden spoon to stir gently, which helps dislodge any air bubbles trapped in the grounds. Cover the jar with its lid and place it in the refrigerator. Allow the mixture to steep for a minimum of twelve hours, but do not exceed eighteen hours, as over-extraction can lead to bitter, astringent notes. After the steeping period is complete, prepare your filtration setup. Place a fine-mesh sieve over a second container or a large glass pitcher. Slowly pour the coffee slurry through the sieve to remove the bulk of the grounds. For a clearer cup, pour the liquid through a paper filter into a clean, chilled porcelain carafe. This double filtration method ensures a silky smooth texture free from sediment.
Serving and Storage Tips
Once filtered, your cold brew concentrate is ready to be stored in the refrigerator for up to two weeks. Keep it in a sealed glass or porcelain container to prevent it from absorbing odors from other foods. When serving, pour the concentrate over ice and dilute with water, milk, or oat milk to your desired strength. A common ratio is one part concentrate to two parts liquid. Experiment with different dilution levels to find your perfect balance. Because porcelain retains temperature well, serving your cold brew in a chilled porcelain mug can enhance the drinking experience by keeping the beverage colder for longer compared to thinner ceramic or glassware. Remember to rinse your brewing vessel immediately after use to prevent any residual coffee oils from drying and becoming difficult to remove.
FAQ
Q: Can I use hot water to make cold brew?
A: No, cold brew must be made with cold or room-temperature water to avoid the high-acidity and bitterness associated with hot extraction methods.
Q: Why is porcelain better than plastic for storage?
A: Porcelain is non-reactive and does not absorb odors or flavors, ensuring your coffee tastes fresh, whereas plastic can impart unwanted tastes and degrade over time.
