Yzurbu Cold Brew Coffee Filter Bags

Yes, these bags are surprisingly durable. Multiple users specifically mention the material is 'strong' and 'doesn't tear or leak grounds' even after 12-24 hour cold brew sessions. The mesh is fine enough to contain grounds effectively while being tough enough to handle the weight when wet. The drawstring closure stays secure throughout the brewing process too.

These work best with about 1/2 to 3/4 cup of coffee grounds per bag. Keep in mind that several reviewers mention the bags are smaller than they expected from the photos, so don't overfill them. If you're brewing a full pitcher of cold brew, you might want to use 2-3 bags rather than cramming everything into one.

The fine mesh does an excellent job for most people—eight reviewers specifically praised how well it contains grounds with minimal sediment. However, there have been occasional quality control issues where some bags let through more sediment than expected. Overall though, you'll get a much cleaner brew than straining through cheesecloth or a standard filter.

Stick to cold brew with these. One reviewer discovered the material melts easily with hot water, which makes sense since they're made of a polyester-like synthetic material. They're specifically designed for cold brewing coffee or iced tea, not hot preparations.

No, these aren't compostable—they're made from a polyester-like synthetic material. A couple of reviewers specifically mentioned being disappointed about this. If you're looking for an eco-friendly option, you'll want to search for organic cotton or other natural fiber brew bags instead.

It depends on how often you brew. If you make cold brew weekly, 200 bags gives you nearly four years of use, which is solid value. Multiple reviewers mention these are technically reusable if you rinse them out, though the drawstring quality may degrade over multiple uses. For frequent brewers who value convenience and mess-free cleanup, the quantity provides good value even as a disposable option.
