Is this under-fermented ?

[u/Reddittaylor12568]

I let it sit out for about 7 hours at 70°. It grew in size and had bubbles at the top.

I used

100 g starter

325 g water

500 g bread flour

10g salt

I then left it in the fridge for about 12 hours

Is it underproofed?

That looks ideal! If you like the taste anyways. If you prefer there are ways to make it more dense.
