I have found Super Kleer K.C to clear my red wines to be very
It contains Chitosan which is a shellfish derivative.
My concern is that someone who might be allergic to shell fish could
have a reaction. I do not know what is left behind in the clearing
that might cause a reaction nor do I know the chemical science to know
if the derivative even straight is safe.
Do you think there should be a warning given on the bottle or to the
person consuming the wine?
If this is a concern, I would suggest you contact the company on this. I
use it too and have never heard of a problem. Does not mean there could not
be one. It is my understanding that a person who is allergic to shellfish
might want to be careful handling it but it all settles out during the final
clearing. But do check.
LD Carlson, the manufacturer responded to my question as to how it
works and if there is any concern.
I'm not exactly sure how the two work together. However I do know
for certain that there is no problem using the Chitosan for anyone that
is allergic to shellfish. The why it is processed destroys any and all
proteins that cause allergy problems.
