Kumamoto (California) Humboldt Bay, California View on Ocean MapAttached to longlines, these Kumamotos have a very different look and flavor from the Washington ones. The genetics may be quite different.

But this one was little bit too fatty. Michael K on December 23, 2018 at 5:55 pm Rating 5 I like the Humboldt Kumamoto much better than the Washington which are not sweet or creamy which is what I love about Kumamoto. I have not tried the Oregon. The Humboldt seem to be fairly consistent, lots of oysters are great sometimes like Welfleets when they are on are some of my favorite but often they are just average. D9sus4 on December 3, 2016 at 1:19 pm Rating 5 I have to say that I have never eaten a Kumamoto that I didn’t like. I think they are one of the mildest oysters raised in the Pacific. That said, there are differences in the quality mostly depending on where they were raised. From Canada to Baja, and they don’t all taste the same. My favorites are probably the ones from Oregon, but they are hard to find here in St. Louis, MO. littledeer on December 18, 2015 at 8:59 am Rating 1 It must depend on when and where. Many people rave about Kumamotos, but I have tried them a few times, from January to May, and have yet to learn to appreciate the metallic taste. That said, there are few oysters a bit of mignonette and a Guinness or Gewurtz won’t help. But I won’t quit trying. Submit a Rating Cancel replySign up now to post your rating, or login here.
