Starch End Point Test

I have been reading Wheelers information on this subject
How important is this test?
I have tried several local Chemists and they do not or cannot assist with the
Iodine Blue Indicator or Iodine + Potassium Iodide he recommends.
He also recommends Using Domestic Iodine
Is this the Aqueus Betadine I already have ?
or is this used in a diluted form

Betadine will do it. But with modern malts a 90 minute mash is easily sufficient to convert the starches into sugars.

It really isn't, unless your thermometer is 10 degrees out either direction, all of the starch will convert.

looking forward to a modified 6X brew this weekend with less hasell?

I've done 61 mashes and never had one fail the starch test.

Never bothered with it myself.

Its a good indication to a new brewer but taste will tell you you have conversion .I pesonally pour a little bit of wort on the seat in the shed and sit in it for ten minutes if I can get the chair off my butt it needs a little longer if I can't I just cut myself out and sparge.
Its called breweing by the seat of your pants

Bit heavy on trousers though
