Rack Wall Mount

The wine rack has a mount with two screw holes, and then there are like three loopy metal pieces that hang off it with room for six wine bottles through the loops. My walls are plaster. I was planning on drilling a hole directly into the wall stud and using plastic expansion anchors. Will this work, or is there a better way? I've heard conflicting reports. I also bought some toggle bolts but it seems like a better idea to go directly into the stud. Do I even need anchors if screwing into the stud? Thanks!
