I purchased this device a week ago. I wanted to start my pour over experience with an easier device then the Hario V60. (Believe me I went back and forth about getting it.) I ultimately landed on the wave 185. For the sake of size I went with the 185 to get more brewed cups out of this. I also purchased along with the wave the kalita wave glass 500 ml.
For size it will brew me 2 decent size mugs. Now back to the wave 185. I decided to give this a try after the several reviews on here and the ease of the brewing process with a flat bottomed pour over will distribute the coffee evenly a lot easier then the Hario V60 as I have heard the V60 is great if you are experienced with pour overs.
Now i have been recently using beans from Devils Head Coffee and adding 30 grams to the 500 ml measurement of the kalita glass. I find that if you are new to the brewing process to youtube some tutorials or even ask a local roastery how to get the best results by demonstrating it for you. I find with the measurements provided I have yielded amazing results. I have brewed several cups of delicious cups of coffee which has been rich in taste and gave me some of the besr cups of coffee I have ever had.
I highly recommend this product for anyone looking to enter into the pour over method of coffee making and avoid gettinf a cheap knock off on amazon to save money. I will update in due time if any problems with the device occur.
