Make Cold Brew Coffee With Filter Bag Step-by-Step Guide

How to make cold brew coffee with filter bag is a must-have skill in our life. Let’s learn more about it.
We have 20 years of experience in producing coffee filter bags. Let’s learn about the process from a different perspective.
Step 1: Prepare the Coffee Grounds
Start by grinding your coffee beans to a coarse consistency. This is essential for allowing the coffee to extract properly without over-extracting or becoming bitter. Measure about 1 cup of coffee grounds for every 4 cups of water.
Step 2: Add Coffee Grounds to the Filter Bag
Place the ground coffee into the filter bag. Tie or close the bag securely to prevent any coffee grounds from spilling out. If your filter bag has a drawstring or closure, use it to seal the top.
Step 3: Mix Water and Coffee Grounds
Place the filter bag into your container and pour cold water over it. Stir gently to make sure the coffee grounds are fully immersed in the water. For a stronger brew, you can add slightly more coffee grounds.
Step 4: Seal the Filter Bag
If you’re using a mason jar or pitcher, ensure the lid is tightly sealed to keep the coffee steeping as it should. If your container doesn’t have a lid, cover it with plastic wrap or a clean towel.
Step 5: Refrigerate for the Perfect Brewing Time
Refrigerate the coffee for 12-24 hours, depending on how strong you want the cold brew. The longer you let it steep, the more intense the flavor will be. Check the brew after 12 hours and decide if it needs more time.
Step 6: Strain and Filter the Cold Brew
After steeping, remove the filter bag from the container and discard the used coffee grounds. If desired, you can strain the cold brew a second time through a fine mesh sieve to ensure it’s completely smooth.
Step 7: Serve and Enjoy Your Cold Brew Coffee
Pour your cold brew into a glass with ice and serve. You can dilute it with water or milk to suit your taste. Add sweeteners, flavorings, or cream to customize the flavor.
Tips for the Best Cold Brew Coffee Using a Filter Bag

Enhancing Flavor with Additives
