I am making my first starter and was wondering about adding yeast nutrient. During wort boiling or when I pitch the yeast. I was thinking that the nutrient should be boiled just like the wort so it is sterilized but, would boiling kill any helpful nutrients? If I add it to the cooled wort am I likely to add contaminants that haven't been sterilized?
The stuff is Fermax Yeast Nutrient by Crosby and Baker, Ltd. I bought at local homebrew supplier.
Thanks in advance.
