Kalita Wave: Guest Barista Review - Part Two
Welcome to the second of our two part guest barista review on the Kalita Wave pour over method! Last week, Collin Moody of Cafe Streets reviewed the 155 Series for us. John spent time on the 185 series for us, discussing his brewing method and the difference between the Wave's flat bottom geometry and conical manual brewers.

On the surface, the Kalita Wave Series of coffee drippers looks and seems fairly similar to other coffee drippers out there: They come in ceramic, glass and metal versions; have a somewhat proprietary filter that works with the particular shape and features of the dripper; and, given the coffee industry's current state of affairs, seem to be yet another in an ever-growing list of brewing toys... er, tools... to obtain and use. I'll give a full disclosure here, though, and state here and now that I am undoubtedly one of those coffee industry nerds who will put a dent in my wallet in the name of "coffee research," all the while grinning over the thought of trying out the latest and greatest toy.Er, tool.
The 185 Series Method
Some months ago, back in the Spring, I believe, I saw a picture of the metal version of the #155 size Kalita Wave dripper. No one in the States had yet obtained the rights to import and distribute the Wave drippers, so, much to my chagrin, I could only sit in jealousy and ponder what made the Wave drippers so different from everything else out there. Therefore, when Wrecking Ball finally did begin distributing them, I immediately bought a #185 size metal dripper and some filters so that I could go to work and see what the excitement was all about.
I was not in the least bit disappointed; in fact, I was quite pleased. I used the parameters recommended by Nick Cho -- roughly 42 grams of coffee, 700 milliliters of water -- but deviated from the pulse-brew he advocates and went instead with a straightforward, continuous-pour technique, all the while aiming for an extraction time of about 3 minutes, 30 seconds. Generally, I found the brews to be clean, sweet, and, if this makes sense, uncluttered while still having complexity.
When my friends over at Prima Coffee decided to carry the Wave Series, I jumped at the chance to review the #185 size. Having already played with the metal dripper for some time, I was anxious to get back into the lab -- my kitchen at home -- and see if I could discern a noticeable difference between not only the Wave drippers themselves, but also the other manual pour-over methods out there. Of course, being anxious to do experiments and actually carving out the time to do them are two very different things, and, much to my guilt and chagrin, I kept putting off the experimenting I needed to do. In the meantime, though, I was still able to brew quite a bit with the various Wave drippers, and I think it fair to say that I was not disappointed. I usually kept my batch-sizes between 30 grams of coffee, 500 milliliters of water and 42 grams of coffee, 700 milliliters of water, though I did occasionally go higher to 60 grams of coffee and 1 liter of water.
Observations and Comparisons
In my casual, not-experimental brewing, I had a few practical observations. First, the paper filters, which are shaped like muffin cups, definitely need to be pre-rinsed carefully as they will easily lose their shape unless the rinse water is poured gently and carefully. Second, careful storage of the paper filters is also a must, as they will lose their shape and get floppy unless held together so as to keep the filter walls nearly straight and upright, which is key in keeping the shape intact during the pre-rinsing process. Trust me, you don't want floppy filters! Third, the #185 size definitely has a sweet spot as far as batch size goes, and I think it is right in that 42 grams of coffee, 700 milliliters of water range. If you're looking for a single pour-over brewer that does, say, just a single, small cup of coffee but will also go all the way up and do a full liter, I'll go out on a limb and say one doesn't exist that does the entire range well.
Now, when I finally got down to doing a series of experimental brews, the first thing I wanted to do was compare it to the Hario V60 02, since that's probably the most commonly used manual dripper out there at the moment, and because the 02 size is comparable to the #185 size Wave dripper. The V60's draw-down time is very, very fast due to the large hole at the bottom and, unlike the Chemex, another popular V-shaped pour-over device, has a thinner filter as well as ridges along the side, both of which speed up the draw-down time. The Wave, however, has three relatively small holes on the bottom, sized similarly to a Melitta dripper, which significantly slow down the draw-down time. Practically speaking, the V60 is a much more pour-dependent brewing device, which means it is less likely to be repeatable, brew after brew.
The second thing I wanted to do was to compare the various #185 size Wave drippers. The ceramic, glass, and metal are all very pretty to look at, but I wanted to know if they worked differently. The biggest possible difference I saw would be in their heat-retention properties, and so I made sure I had out my digital thermometer while I brewed a lot of batches of coffee. My findings? Well, to be honest, I couldn't really see a difference between the three, nor could I taste one. I logged a fair amount of data and spat out a lot of coffee, but there wasn't enough clear deviation one way or another to conclusively say that any one dripper had better -- or worse -- heat-retention properties. I think a part of this is due to the fact that the filters themselves move the coffee slurry away from the walls of the dripper, thus allowing air to be an insulator to keep the drippers themselves from sucking away any heat from the slurry.
As I conclude, I'd like to go back to the idea of the #185 series having an ideal batch size -- roughly 42 grams of coffee, brewed with 700 milliliters of water. Without getting too technical, this, I believe, is inherent to the design of the drippers and filters, and has a lot to do with bed-depth and ideal extraction time. The Kalita Wave Series does a very, very good job of allowing close to ideal conditions for extraction, and the #185 size works quite well for those wanting two to three cups at a time.

For most companies it's hard to find motivation for pushing out new products if you find yourself on top already. This is not, however, the case with La Marzocco. The Italian based espresso machine manufacturer continues to push the envelop when it comes to innovations in espresso machine technology. The newest line from La Marzocco continues their progression in the specific areas of temperature stability and pressure profiling. We've discussed the Strada Electronic Paddle version in detail in our Strada EP blog post and listing for the 2 Group Strada EP. The Strada Mechanical Paddle employs technology similar to the Mechanical Paddles on other La Marzocco models but with a few new features including individual pressure gauges, digital PID control, and dedicated group boilers.
Hario Skerton grinder is handy for manual home and travel grinding, it can also be slightly more cumbersome for an extended road trip where only a small amount of grinding will be done (for a more detailed comparison of the two grinders, check out this blog post: Hario Skerton vs. Mini Mill). For those trips (or homes) where a minimal amount of grinding is needed, the Hario Mini Mill Slim is the perfect grinding solution. The Mini Mill employs adjustable conical ceramic burrs for grinding any of the wide range of grinds employed in today’s coffee market. It can effortlessly handle 24 grams of anything from fine espresso to a coarse French Press setting. Because of its lightweight (0.5 lbs) and sleek plastic body, the Mini Mill easily fits into small carrying bags and suitcases without adding a lot of extra weight. This, in conjunction with the Aerobie AeroPress coffee maker, has the propensity to make excellent coffee anywhere hot water and fresh beans are available.
The Hario Mini Mill is a traveling coffee enthusiast’s dream come true.... and with its ability to grind to the fine quality needed for espresso, it can be paired with a hand-held travel espresso maker such as the mypressi TWIST (and an excellent choice of beans) to achieve a quality rivaling the product found in many high-end espresso machines. Whether the need is grinding beans for a french press, Aeropress, or mypressi, the Mini Mill Slim is the perfect travel solution.
As the interest in specialty coffee continues to increase, so does the interest in brewing methods that best compliment the quality and ideals of specialty coffee. Up until this point there have been limited options when it comes to pour over brewing devices that offer both a small learning curve as well as excellent results. Garnering praise for both their calculated design and ease of use, the Kalita line of pour over brewers are helping that small list of brewers grow. The Kalita Wave Dripper is being offered in both small (1-2 people) and large (1-4 people). The small size is offered in both glass and stainless steel while the large size is offered in glass, stainless steel, and ceramic. For an overview of the unique style the Kalita Wave Dripper brings to the pour over method, a feature chart that overviews the design, technique, and advantage can be found below.
