In addition to the above by our very experienced friend, I would say that most people that I know who usually want medium-well or well-done steak have truly enjoyed the medium sous vide steak that I have served them.
Many who order medium-well are really only ordering that because they fear ‘bloody’ juices from a steak. The red juices are not blood. If there was any juice left in a medium-well steak it would still have a reddish hue.
