Hi Tulin!
I found it at Whole Foods out here.  You might be able to find it at a  "health" store with a good bulk section.  Or maybe a gourmet store - like Fox &amp; Obel downtown??  If not, I bet you can find it online.  Try this site: http://www.bobsredmill.com/organic-hard-red-spring-wheat.html  Bob's Red Mill is a line that I see at Whole Foods a lot, and they seem to be a reputable supplier.  Good luck!  Let me know how it turns out!
