Rumble Jar – Next-Gen Cold Brew Coffee Maker for Mason Jars
Introduction
If you’re looking to make professional-quality cold brew coffee at home, the Rumble Jar – Next-Gen Cold Brew Coffee Maker is the perfect choice. With its innovative design and high-quality filter, you can enjoy stronger and fresher cold brew coffee. This buying guide will help you select the right Rumble Jar for your needs.
Filter Design and Extraction
The Rumble Jar features a 200 micron filter made of 18/8 stainless steel. This filter is specifically designed for coarse ground coffee, allowing optimal water circulation and extraction. Unlike fine mesh screen filters, the Rumble Jar’s filter is ideal for cold brewing and produces a stronger coffee flavor.
Fresher Coffee with Airtight Seal
The Rumble Jar’s filter rests inside a Mason jar, allowing the jar’s lid to maintain an airtight seal. This ensures that your cold brew stays fresh and prevents oxidation. The airtight seal also makes the jar leakproof and portable, eliminating the risk of coffee spills.
Durable and Innovative Design
The patent-pending capped-filter design of the Rumble Jar features an ultra-sturdy 18/8 stainless steel filter. The filter includes a food-grade silicone cap, available in multiple colors, that keeps coffee grounds sealed inside while acting as a shock absorber to protect the filter. This design eliminates the issues of flimsy mesh filters that can produce weaker cold brew and easily fray, rip, or get clogged up.
Simplified Brewing Process
The Rumble Jar makes brewing professional-quality cold brew coffee at home incredibly simple. After adding your coffee grounds and water, tighten the lid and rotate the jar horizontally/sideways 2 or 3 times to activate the brewing process. Let it sit overnight, and your cold brew will be ready in the morning. Cleanup is quick and easy too.
Compatibility and Capacity
The Rumble Jar is compatible with wide-mouth 32oz Mason jars (not included). The filter, made of stainless steel with a food-grade silicone cap, is designed specifically for wide-mouth jars. It’s important to note that the stated 1-quart capacity refers to the volume of the Mason jar, not the filter itself. The Rumble Jar is BPA-free and dishwasher safe.
Conclusion
If you’re looking for a next-gen cold brew coffee maker that produces professional-quality cold brew coffee, the Rumble Jar is the perfect choice. Its innovative design, durable filter, and airtight seal ensure stronger and fresher coffee every time. With its simplified brewing process and compatibility with wide-mouth Mason jars, the Rumble Jar is a must-have for any coffee enthusiast.
