Tips for the Perfect Brew

• Maintain the ideal coffee-to-water ratio for balanced flavor․
• Use a coarse grind to prevent over-extraction․
• Adjust steeping time to suit your desired strength․

Coffee-to-Water Ratio

The coffee-to-water ratio is crucial for achieving the perfect brew with your Rumble Jar․ A general guideline is to use 1 cup of coffee for every 4 cups of water, but this can be adjusted to suit your taste preferences․ For a stronger brew, opt for a 1:4 ratio, while a 1:6 ratio will yield a smoother, less concentrated coffee․ When using the Rumble Jar, start with 115 grams of coarse-ground coffee for 32 ounces of water, then fine-tune the ratio based on your desired flavor profile․ Proper measuring ensures consistency, so invest in a scale for accuracy․ Experimenting with this ratio allows you to tailor your cold brew to your liking, whether you prefer bold or light flavors․

Grind Size Recommendations

The grind size of your coffee beans plays a significant role in the brewing process with the Rumble Jar․ A coarse grind is highly recommended, as it allows for optimal extraction without allowing too much sediment into the final brew․ Using a burr grinder to achieve consistency is ideal, as blade grinders can create uneven particles․ Aim for a grind size similar to kosher salt or coarse sand․ Avoid fine grinds, as they can lead to over-extraction and a muddy texture․ Conversely, a grind that’s too coarse may result in under-extraction, yielding a weak brew․ Experiment to find the perfect balance for your taste preferences, ensuring the grounds are uniformly sized for the best results․ The Rumble Jar’s filter is designed to work seamlessly with this coarse grind, delivering a clean and flavorful cold brew every time․

Steeping Time Optimization

The steeping time for your Rumble Jar cold brew is crucial for achieving the perfect flavor․ The standard recommendation is to steep for 18–24 hours, allowing the coffee grounds to slowly infuse into the water․ However, this time can vary depending on personal taste preferences․ For a stronger brew, extend the steeping time slightly, while a shorter steeping time yields a lighter flavor․ Factors like the coffee-to-water ratio and grind size also influence the optimal steeping duration․ To ensure consistency, steep the Rumble Jar in the refrigerator to maintain a stable temperature and prevent over-extraction․ Experiment with steeping times to find your ideal balance, as this step directly impacts the flavor profile of your cold brew․ Proper steeping ensures a smooth, full-bodied coffee every time․
