We have been in the tile and stone business for over 47 years. My advice is to always complete your own testing to determine what will happen to even a properly sealed and maintained natural stone. We recommend using Oceancare sealing products. To test obtain a small 12 x 12 sample and properly seal it. Then subject the stone to a similar type condition for which you will use the stone. If you would leave lemon on the counter top for 30 minutes then do the same. If you immediately wipe up wine stains, then I would do so. This is the only way to truly answer what will stain or not stain and how a natural stone will function in real life conditions. My guess is if you use a very high quality sealer and reseal it as required, then you should be fine. Also be careful about sealer guarantees to see what they are actually guaranteeing against. Most of the time it is not replacement or refinishing of the stone, but rather with receipt, supplying another gallon of sealer.
