Hello, i am doing a cab /merlot and currently going through mlf.Today, after 4 day of mlf and about .75 inch of fine lees sediment at the bottom i noticed the wine has a pronunced taste of lees/ yeast. At this point should i rack the wine ?(this would be the second racking).The mlf seems it has slowed down considerably although the temp and ph are whitin range. Also i noticed the tannins are v noticeable and i was looking to add egg whites.When or should i adress the strong tannins at this early stage?Thank you.
