Probably another one rusting away somewhere too. I find the V60s to give me the most consistent and most delicious coffees out of all the brewers. The user above me suggesting that all the V60s are capable of making the same amount of coffee and how different sizes are nonsense.. is... well... nonsense. The V60-01 and 02 have different sized openings and that contributes to a lot. I find the 01 is great for 12 ~ 18g or so, and the 02 works for around 25 ~ 35g or so. I've tried making smaller batches in the V60-02 (before I got the 01) and I had similar results as you, just less vibrant, boring, and more difficult to dial in.
The V60 requires the finest grind out all the brewers and I think that really contributes to a better extraction and more intense flavor overall. I do also really like my Chemex, but the coffees are usually ever-so-slightly less vibrant than the V60 brews but occasionally they are godly.
I found the Kalita Wave 155 to be a horrible brewer. Even though it's supposedly more consistent and easier to brew with, I didn't find that to be true at all. It still requires dialing in your grind and a precise technique for an even extraction. In fact, I find the cupcake filters to be infuriating since grinds get stuck in the folds (how is that supposed to be a more even extraction?). You can develop techniques to get the grounds out of the folds, but it will most likely result in you bypassing the coffee bed and pouring in between the filter and the brewer. Swirling certainly doesn't work well for that, in my experience. If you do end up with a brewer, don't get the 155, it will definitely not meet your 25-40g requirement.
The StaggX is even worse than the Kalita Wave. It is double walled, which is nice I suppose, but it has the same cupcake filter problem. On top of that, it doesn't just automatically sit level on top of cups or carafes because of some horribly weird design choice to remove the skirt. Oddly, it does sit perfectly level on my Hario decanter, but everything else requires a balancing act and is pretty much guaranteed to be not level in one direction as it's a 3D problem.
I'd suggest the 6-cup Chemex or the V60-02. The Chemex would give you a little more of a unique experience, unique flavor profile and can definitely handle the sizes you're looking for. But, the V60-02 would probably give you the coffee you're looking for and would require very little learning... and it's cheap!
Thanks for this perspective, maybe I should just continue tinkering with the v60 03.
I messed around further this weekend; I found 1100 g water to 80-82 g coffee at 20 grind to work fairly well, provided I agitate with spoon during bloom. When scaling down, I found 550 g water to 40g coffee at 14 grind to be somewhat comparable.
As I think about it, I am somewhat surprised that Hario didn't adjust their hole/opening size for different sizes (01 vs 02 vs 03). This means that with each larger size, the ratio of average coffee size to opening size is going to increase, which makes each size perform differently.
Have you tried out the December Dripper?
Will be curious what you think of the Espro bloom.
