Kumquat fruit ID

[vnomonee]

I picked these up from an asian grocery store. They were labeled as "Japanese kumquats" nothing else.

They are not sweet in the middle, although some did have a hint of sweet. They are definitely acidic but not as much as a Nagami...




I don't think they are Meiwa although that was my first guess. I looked at pictures of Marumi but those had a small depression at the base (not as pronounced as a Fukushu) but I also saw pictures of completely round fruit so the pictures online could be misidentified.

From the taste description definitely sounds like Marumi or Fukushu, but yes in my experience these two usually have a dimple at the bottom.  Maybe there is some varience.

The appearance looks like Meiwa

Yes unless these are not fully ripe Meiwa I'm thinking that they are Marumi or a variation.

I just tasted a Meiwa fruit off my potted tree that isn't all the way ripe (colorwise at least) and found that they still have sweeter flesh compared to these grocery store kumquats
