Does anyone know anything about yeast hulls and should they be used on
both red and white wine?
I have been led to believe that they are very good at detoxifying
wine.

I'm not sure what you mean by "detoxifying wine". However, yeast hulls are
often added to prevent stuck fermentations. Some think this is due to the
hulls providing nutrients to the wine. However, I just came across this
paper describing the properties of yeast hulls in removing components that
are toxic to the yeast. I suspect that's what you were driving at when you
said they detoxify?
