Discover the pros and cons of cold brew and hot brew methods using a mason jar. Learn step-by-step techniques, tips, and which suits your taste.
Brewing coffee in a mason jar is a simple, versatile, and eco-friendly way to enjoy your favorite beans. Whether you prefer the smooth, low-acid taste of cold brew or the quick, aromatic satisfaction of hot brew, a mason jar can do it all. In this guide, we'll compare these two popular methods, walk you through each process, and help you decide which one fits your lifestyle.
Mason jars are not just for canning; they are perfect for coffee brewing because they are sturdy, easy to clean, and allow you to see your brew. Plus, they are reusable, reducing waste from single-use coffee makers. Let's dive into the details of cold brew vs. hot brew in a mason jar.
Cold Brew in a Mason Jar: The Low-Acid Favorite
Cold brew involves steeping coarse coffee grounds in cold water for 12 to 24 hours. This method extracts flavors slowly, resulting in a smooth, less acidic, and naturally sweet concentrate. It's perfect for those who find hot coffee too bitter or acidic. To start, you'll need a mason jar, coarse ground coffee, cold water, and a fine mesh strainer or cheesecloth.
The process is simple: add coffee grounds to the jar, pour in cold water, stir gently, and cover. Let it steep in the refrigerator for at least 12 hours, then strain. The resulting concentrate can be diluted with water or milk. For a ready-to-drink option, try Chamberlain Coffee's Organic Cold Brew Elephant Large Coffee Bags, which are designed for cold brewing and offer a rich, balanced flavor.

- Use a ratio of 1 part coffee to 4 parts water for a strong concentrate.
- Steep for 12-24 hours; longer steeping increases strength but may add bitterness.
- Strain twice for a cleaner cup.
Hot Brew in a Mason Jar: Quick and Aromatic
Hot brewing in a mason jar is essentially the immersion method, similar to a French press. It's faster than cold brew, taking only 4-5 minutes, and produces a full-bodied, aromatic cup. You'll need a mason jar, medium-fine ground coffee, hot water (just off the boil), and a strainer or a reusable filter.

To hot brew, add coffee grounds to the jar, pour hot water, stir, and let it steep for 4 minutes. Then, press the grounds down with a spoon or strain the coffee into another container. This method highlights the coffee's brightness and complexity. For a delightful twist, try Chamberlain Coffee's Organic Hazelnut Coffee Blend, which offers a nutty, cozy flavor perfect for hot brewing.
- Use a ratio of 1 tablespoon of coffee per 6 ounces of water.
- Steep for exactly 4 minutes to avoid over-extraction and bitterness.
- Stir gently before straining to ensure even extraction.
Cold Brew vs. Hot Brew: Which Should You Choose?
The choice between cold brew and hot brew ultimately comes down to your taste preferences and schedule. Cold brew is ideal for those who enjoy a smooth, sweet, and less acidic coffee, and it's perfect for making iced coffee. It requires planning ahead, as it takes at least 12 hours. Hot brew is quicker and delivers a more traditional coffee flavor with higher acidity and more pronounced aromatic notes.
If you're new to mason jar coffee, consider starting with cold brew because it's forgiving—over-steeping won't ruin the taste as easily. For hot brew, you'll need to be more precise with time and temperature. Both methods are cost-effective and don't require special equipment beyond a mason jar and a strainer.
For convenience, you might also explore Chamberlain Coffee's Organic Medium Roast Cold Brew Singles, which are perfect for single servings and eliminate the need for straining. Or, if you want to elevate your experience, pair your brew with a Navy Ceramic Mug to keep your coffee warm and stylish.
- Cold brew: smoother, less acidic, longer time, great for iced coffee.
- Hot brew: quicker, more aromatic, higher acidity, best for traditional coffee.
- Both methods are simple and require minimal equipment.
Whether you choose cold brew or hot brew, a mason jar is a versatile tool that makes brewing coffee easy and enjoyable. Experiment with different roasts and grind sizes to find your perfect cup. With a little practice, you'll master both methods and impress your friends with your barista skills.
