Dugger has it right. You don't want the wine to set on the sediment too long.
If you are bulk aging, you will want to rack off the sediment periodically. If you are bottling right away (which I would never do except for a summer wine), it is a good idea to rack off all the sediment into a clean container; then bottle from there. This way you don't risk getting sediment in your bottles and it helps get rid of that last little bit of CO2 that might still be lingering.
After bulk aging various lengths of time, when I bottle, I rack into a fermentor bucket and bottle from there. (I do this so I can utilize the spicket on the bucket. I use a bottling wand, but I like to slow down the flow just before the bottle is full, so I don't get all the overflow. For me, bottling seems to always be a messy job.)
