Urea in nutrient
- Hello to all group members. It is good to see that the group is
continuing to flourishing and stimulating discussion on the subject
of distillation. I have been very busy with the business and not had
the time to devote to the group but I get all the digests. I would
like to take the opportunity to thank Tony for looking after the
group and keeping it going well, thanks Tony.
Anyway, I see that the age old subject of urea as an ingredient in
nutrient has risen like a phoenix again. I would like to put this to
rest once and for all, as some of the members know, I did a lot of
research on this when it first came to light in 1997.
I believe the issue was initially raised more to score political
points than as a genuine concern for the law in New Zealand or
peoples health - but that is another issue.
According to 'The Food Regulations 1984, Amendment No. 5' dated 2nd
December 1991 regulation 235, General alcoholic drinks, subclause 3
says "General alcoholic drinks may contain any of the following:",
paragraph (i) "Yeast nutrients, except urea"
Which is what has been quoted in past correspondence and always
referred to when discussing the issue, however:
'The Food Regulations 1984, Amendment No. 9' dated 10th of October
1994 regulation 101, (3) states "Regulation 235 of the principal
regulations is hereby further amended by revoking paragraph (i) of
subclause (3)." ie the exception to urea above is now revoked.
On seeing this I contacted the New Zealand Health Department and
requested, under the Official Information Act, all the paper work as
to why the original banning and why the lifting of that ban.
Of course, I got screeds of paper but the story is that the ban was
instigated because of research done in England that pointed health
risks of urea as an ingredient for fermentation. Thus it was banned.
It was later realised that although these chemicals were present in
the fermented wash, they were not present once the wash had been
distilled. It appears that they are not carried over in the
distillation process, thus the ban for this type of alcoholic product
I hope this all helps to clear the matter especially for those
overseas members who may be questioning the ingredients in their
