The Stainless Steel Kalita Wave is easy to use, easy to clean and sure looks nice. This dripper is a favorite around the Sweet Maria's office. The stainless steel construction looks nice too. The three small holes in the base allow for good drainage while being restrictive enough to give you good extraction.
The Kalita drippers are the first brewers we have sold that use flat bottom "cupcake" style filters. A flat bottom allows for the bed of ground coffee to form into a wider shape in comparison to a cone or V-shape brewer. So what does this all mean? Is a flatter bed of coffee better? Not necessarily...but we think it's easier to evenly pour hot water through a wider, flat surface that drains at a moderate pace. Kalita drippers are a favorite around the Sweet Maria's office. The three small holes in the base allow for good drainage while being restrictive enough to give you a good extraction. Aside from the mild horizontal ridges the Kalita's walls are smooth and the waves on the wall of the filter is what creates the space which allows coffee to flow filter through the paper. We would trust this dripper to withstand the abuse of travel, camping, etc., but it's not a thick-walled beast. One could easily bend the metal with a little force. It's lightweight and has a delicate feel to it. The plastic handle has a surprisingly nice feel and serves as insulation when lifting the dripper off of your cup.
You will have to buy Kalita Wave #185 sized filters. You might be able to buy filters made by another company but they will be hard to find.
