Barley as cow feed....
Dear Sir,
I will be able to explain ( whether Barley can be used OR NOT ) to you on phone ONLY as its too deep a subject for explaination on the email.
I always like to offer advise on Call since explaining is much easier than writing & clarity of communication is TWO sided whereas communication by mail/post is ONE sided.
Secondly I would also like to know what other ingredients you are using.
You may please see my blogs & get my number therein.
