I agree with grapeman that ordinary bottles are designed to exclude oxygen, and thus are not really suitable for long-term storage of wine. However, I think you will get less oxidation before you bottle this if you put it in two 5 L plastic containers than if you put it in one 23 L container.
Another option is finding larger glass bottles. You could use six 1.5L bottles, for example, although you would need 6 airlocks, etc. Any chance of finding 4 L or 5 L glass in your part of the world?
