Review on ☕ Kolob Brew Tube - Stainless Steel Mesh Reusable Filter for Wide Mouth Glass Mason Jar - Cold Brew Coffee Maker, 1 or 2 Quart by Lisa Phelps

I used a smaller cold brew system that works like KolobCo, but I needed more concentrate. The features that drew me to the KolobCo whistle were the larger brew volume and thin stainless steel screen, with the bottom of the whistle also being made of mesh, which allows the beer to drain more efficiently from the bottom. I haven't gotten to the bottom of the concentrate jar yet, so I don't know if there's any leftovers. If there's any left over it's not a problem as it stays at the bottom of the glass instead of pouring into my cup. I grind beans in a burr grinder on coarse setting and get a little sediment that came with my smaller brewing system so wouldn't be surprised if it shows up with this pipe, hey it's coffee! It adds flavor to the drink, you don't have to filter or drink it like I said, it stays at the bottom of the glass or cup when it gets there. Just don't drink the last spoonful. I also like the ability to turn the jar upside down to soak the bottom part of the time. It turns out to be an excellent concentrate for cold brewing.
