Default Iodine testing...

I went to wal-mart today to get some iodine to test conversion with and they didn't have any. The pharmacist told me they didn't sell it any more because of meth dummies or some such crap. So I got something that is basically a generic betadine solution. When I tested I didn't see purple...I didn't really expect to though because I mashed for abt 75 mins instead of 45-60 because...well, just because.

So will betadine work as a test agent?

BTW...the brew day turned out great...

I'd go to regular drug store and get some. Some people use iodophor sanitizer. I don't know about betadine. sorry

I'm not talking abt sanitizing...I use Star San for that. I'm talking about testing to see if you have reached full conversion.

Boil some flour to gelatenize it. Test this with you solution. If it turns black purple you are fine.

Schlenkerla is talking about Iodophor because it has iodine in it. If you can't find iodine, you can find Iodophor.

Thanks - I should have stated that iodophor has iodine.

Ok, sorry my bad.

I did the test with flour and it worked. So the sample that I took from my MLT yesterday was fully converted. Beersmith said I should have gotten 1.035 OG and I got 1.034 and this was my second ever all grain so I am pleased. That was even after having to add a half gallon of water to the finished wort because I had forgotten about the 90 min boil instead of 60 like I'm use to. It was a five gallon version of BM's Sterling Gold.

Betadine ought to work, because the same compound responsible for antiseptic properties also reacts with the starches.
