Hanging Wine Rack

The wine rack has a frame with two screw holes, and then there's like three pieces of metal hanging off Loopy it with room for six bottles of wine through the loops. My walls are plaster. I intend to drill a hole directly into the wall studs using plastic anchors. Does this work or is there a better way? I have heard conflicting information. I also bought some toggle bolts, but it seems to have a better idea to go directly into the post. Do I still need to screw anchors if the amount? Thank you!

The best thing is to screw directly into the pin, otherwise you may lose your wine.
You do not need an anchor if you do that, just regular wood screws at least two inches long

I rock bolts.

You do not need an anchor if you're sure you hit the poles.

so striking poles without anchors necessary if not using toggle bolts, plastic anchors suck.

Anchors do not work in the nails.
