I need advice for building a wine rack

Twich22 thought this was worth mentioning said

I have a decently sized wine cellar, about half of a standard bedroom in size. However I only have half of the wine racks needed to fill it, and those wine racks are all full. I am currently just stacking boxes for the time being but would like to install new wine racks when I can.

I was thinking of just building my own. The other wine racks in there were custom built but they are expensive.

Does anyone have any advice or experience in this regard? I am looking for something cheap and/or easy to build but also space-effective. I want to be able to fit as much wine as possible! I have not really built much in my time but am willing to learn.

I was thinking about a wire-rack, or maybe something like a book shelf. Any thoughts are appreciated!
