No potassium iodine, just used iodophor which I believe works perfectly well for doing an iodine test.louistoo said:Where did you buy potassium iodine Welly?

You got a location we can buy this MHB? I've tried betadine as an indicator, but AFAICT it's fairly useless in the brewery.MHB said:No where near as well as proper Starch Indicator, Its a blend of Iodine and Potassium Iodide usually in 20-30% alcohol and some times with a few other ingredients to make it more sensitive.
Made properly it can show positive for ppb levels of starch and is very clear in its indication at brewing concentrations.

Yes. There is many comments and conversation on S-04 doing this. 1.020 is the common number. There is a little tlc you can do to get it to work better but I just don't use it but many do with good results.Brewno Marz said:Restart of thread and on topic.
Made a small batch (20 litre) of oatmeal stout on Good Friday and used Fermentis S-04 yeast. Fermentation took off and SG got to 1.020 in 3 days. Yesterday, 4 days further on and still at 1.020 and no signs of yeast in suspension. So, I gave the fermenter a big shake and then today still no movement. SG stuck at 1.020 and no airlock activity. Is this a characteristic of the S-04 yeast?
If only I had a dollar for every time I've responded to this. S-04 is a perfectly fine yeast, you just have to know it's quirks. Search for one of my previous responses for specifics.
