Mushroom Sauce – shelf life

I’m going away this weekend and would like to do some of the prep for my meal in advance. How long would a homemade mushroom sauce (no flour, just reduced cream, wine, garlic and mushrooms) last in the fridge? Would it be ok to freeze it? Would freezing it not affect the quality of the mushrooms and cause the sauce to split when you reheat? I would prefer to keep it refrigerated for 4 days, but don’t want to heat up ” sour” sauce.
