If I'm not mistaken, flow rate will always be faster initially during the pour, but will slow down greatly as time goes on. The water has to 'work' more to get through the coffee. This happens with all filter designs, i.e. truncated cone, V-shaped, and flat bottom e.g Kalita Wave.
Wow, first time I've heard of the Sanyo dripper. How was your experience using it?
I have 2 of the Daiso plastic drippers, bought in my early days of home brewing. They correspond roughly to Kalita 101 & 102 size, 3 holes. But hole size is different between the two, one has larger diameter holes than the other. Strangely enough, I've never been able to get a good cup of coffee to my liking from these Daiso drippers.
I recently made an order from Perk Coffee. You can try them as well. Good quality beans. They roast every Monday or Tuesday and ship the coffee out to you the day after, so if you make your order during the weekend, you'll be able to receive your coffee by Wednesday. Just a few days after roast. Still have to let the beans rest, though.
Arkib Kopi always roasts to order. And IIRC Reframe Coffee Roasters does too.
I thought the Sanyo Aritayaki 三洋有田烧 has been quite common for some time?
It shares some similarities with the Kalita 102 but the botton is much well-designed. You will see more ribs to support the paper filter, allowing airflow and resulting in faster flow-rate than the Kalita 102. However, it is still much slower than a Haria v60. In my pass experience, the Sanyo Aritayaki will be a bolder coffee, and paired with lower water-temp and medium size grind, you will get a sweet & bold coffee that still retains its acidity.
However, our shop replaced it with the ZeroJapan which works nearly similarly but has a better built quality.
