Hi Lika & Shane
that’s interesting that these small beans are difficult to find even in Japan. The problem for us in providing small beans is that we don’t have a way to sort the smaller from the larger bean. I would think it was done by hand and eye traditionally. We use different machinery due to the volume of our product. We start with screenings where smaller sized things fall through the screen but the small beans are not small enough to be drafted off with this method. Then the beans move onto the gravity tables which works on weight and removes small stones and heavy things but even smaller mung beans have similar gravity.
To invest in the right equipment, we’d want to have a good measure of demand. I suggest that you start asking your favourite retailers (usually the organic specialty shops) and tell others to start asking for it. I have flagged your interest to the product team. It also needs to come from the retailers/ manufacturers.
