What would this sauce be called? I have a nice sized chuck roast in the sous-vide circulator, I can see that there are some great looking juices accumulating in the bag. I want to make a sauce out of those juices with butter, garlic, herbs and wine reduction. There is a name for that kind of sauce, but it's escaping me at the moment. So that I can Google for recipes, what would a sauce like that be called?
Using the meat juices from cooking is a jus :) adding wine along with the aromatics might change it to be a "red wine jus" or I've also seen a "port jus", or the jus could be used in a Madeira sauce, etc.


  served in the natural juices that flow from the meat as it cooks.
