Quick answer
Alto Cold Brew Filter Bags let you brew smooth, concentrated cold brew in any container without a special maker. Just fill, tie, steep, and enjoy.
Why use filter bags instead of a cold brew maker?
Alto Cold Brew Filter Bags eliminate the need for a dedicated brewer or mesh strainer. They are biodegradable, compostable, and plastic-free, so cleanup is as simple as tossing the used bag. The included funnel makes filling mess-free, and the drawstring tie keeps grounds contained during steeping.
The trade-off is that you cannot control the water flow or agitation like you can with a full cold brew system. For most home brewers, the simplicity and zero cleanup more than make up for it.
How to brew cold brew with Alto filter bags
- Fill the bag with coffee: Open an Alto Cold Brew Filter Bag and place it inside the included funnel. Add about 1 cup (100–120 g) of coarse ground coffee. Do not overfill—leave room to tie the bag securely. Common mistake: using a fine grind can clog the bag and make the brew bitter. Stick to coarse.
- Tie and place in your container: Pull the drawstring to close the bag tightly. Place the bag in a clean jar, carafe, or pitcher. For a standard 1:4 concentrate ratio, add 4 cups (950 ml) of cold or room-temperature filtered water. Checkpoint: make sure the bag is fully submerged. If it floats, weigh it down with a clean spoon or glass.
- Steep at room temperature or in the fridge: Let the bag steep for 12–24 hours. Room temperature steeping extracts faster (12–16 hours); fridge steeping gives a smoother, less acidic result (18–24 hours). Taste after 12 hours and adjust next time. Common mistake: steeping longer than 24 hours can over-extract and create bitter flavors.
- Remove the bag and enjoy: Lift the bag out by the drawstring and let it drip for a few seconds before discarding. The remaining liquid is a concentrated cold brew. Store it in the fridge for up to two weeks. Checkpoint: dilute with water or milk to taste—start with a 1:1 ratio of concentrate to water.
