Huckleberry species that tastes like spinach?

Last year, my mom's neighbor got some free Huckleberry seeds from a seed company (as part of a larger seed order), and planted them, and let my mom pick them.

According to my mom, they tasted terrible - like spinach. Adding sugar to them didn't help, as then they tasted like spinach with sugar.
But my mom made fantastic "wine" out of them. So much so that at Thanksgiving last year, pretty much the whole family was saying it was the best wine she's made yet.

I want to plant the same species, but apparently, there are multiple plants people call Huckleberry.

This year, I bought "Chichiquelite Huckleberry" from Baker Creek and grew them - it wasn't the correct thing. The wine was decent, but not what everyone was raving about last year.

I've asked the neighbor what seed company it was that sent them, but haven't got a response.

Any idea what this might've been?

I'm 95% pretty sure it was an annual, the neighbor said it was "huckleberry" but could've lost track, and it ostensibly tastes like spinach.

This is probably the most common annual called huckleberry:
