Mash ph adjustment 14 years 1 month ago #7

If its a conversion problem then do a starch test:

Get a little bottle of "Tincture of iodine" from the local chemist.

Get a clean white saucer.

Put 1 drop of iodine on the saucer ( there is usually a dripper built into the bottle ).

The Iodine is brown at this stage

Add a few drops of wort and mix with the tip of a knife.

If the mix turns blue then this means that there is starch present. It is super sensitive test!!

If the mix doesn't change colour the you have 100% conversion of starch to fermentables.

Do it at the start of the mash and it will turn blue!!

Hope this helps

Attempting to post my water report, the long one is pre softener, the other one is from the kitchen tap just tested for hardness and iron reduction....,

Bought the iodine, will do that test at my next brew, but I'm definitely missing OGs. Problem with my pre-softened water is that the iron is off the scale and tastes bad, its at 998ppm, dont think itd make a nice brew. My softener uses a product called crystal-right 200. I emailed the suppliers to ask what that can be expected to do given my water profile and didnt get an answer. I might ring them this week because I'd love to know what effect it has on the pH, without paying for another test.

Crystal Right
Is the only multipurpose water treatment media that removes iron, manganese and hardness and raises pH and can remove hydrogen sulphide al in one process.

Crystal Right silica crystals are a natural choice for today's water conditioning systems. No other product does so much to condition problem water in a single pass.

These zeolite crystals come from a sodium aluminosillicate carefully produced and processed by Mineral-Right using an exclusive technology. Through its unique crystalline structure, Crystal Right provides superior removal of hardness, iron and manganese while raising pH levels of acidic water at the same time.
Unlike round, resin beads, Crystal Right crystals provide better filtration, and are thoroughly cleaned by backwashing faster than ordinary resins without loss of product.Explore the many advantages of a single-pass, single-system product that is setting new industry standards. Your dealers and customers will be impressed.

Crystal Right 100 is the most durable of the manufactured minerals. It raises the pH value of acidic water while it reduces hardness, iron, and manganese. Low pH waters tend to be more corrosive than neutral or higher pH waters. This pH adjustment and reduction of undesirable minerals is maintained by the excellent filtration and backwashing properties.

Crystal Right 200 is a select, high capacity mineral used for the reduction of hardness, iron, and manganese from water. The mineral is a crystalline structure manufactured to stringent specifications and quality control (screen analysis) guidelines. This extra effort assures the highest softening capacity of the zeolites. In addition to these high capacities, the consistently superior performance is possible because of its excellent filtration and backwashing characteristics.

Crystal Right works best on "clear water" iron and manganese, where a water sample is clear of precipitated iron when freshly pumped. We have installations operating with iron or manganese levels up to 15 ppm and producing water with less than 200 ppb iron and 50 ppb manganese. Above 15 ppm we do have systems producing good treated water but residual iron and manganese may exceed the 200 ppb and 50 ppb levels. As Crystal Right is an inorganic mineral, its lifetime can be reduced on very low TDS water so we do not recommend its use with TDS of less that 80-ppm or a hardness of less than 50 ppm.
Crystal Right 100 is used where the raw water pH is between 6.0 and 7.0 (if the pH is lower than 6.0 then conventional pH correction will also be needed)

Crystal Right 200 is used where the raw water pH is 7.0 or above, its advantage in this situation is a higher capacity.
Both minerals will remove calcium and magnesium hardness so it is easy to test if the system is working by testing the water hardness. If the water is soft, the unit is working.

Mash ph adjustment 14 years 3 weeks ago #12

Did an overnight mash on wed night. Doughed in and hit slightly low temp of 66.7. 6kgs lager malt with 3% wheat cos I like a nice head. Used 35litres tesco bottled water. Mixed 35g dls into dry grains before dough in. Checked mash ph after dough in and it was 5.8ish. Mashed overnight, lost about 10deg over 10 hours. Ph 5.3 to 5.5 in morning before mash out. Heres iodine test before mash out:
I think it indicates good conversion, can anyone confirm?
Mashed out at 78deg and pulled bag. Had to leave house for a few hours so set stc1000 to 80deg so it wouldn't lose much temp. Mash was cloudy when I left but when I got back the cloudiness had cleared and clumps were floating in it. Anyway continued with boil. Had a cutout with my buffalo 20mins into boil. Gave it a stir every few minutes after and it didn't cutout again. Wondering if cutout was related to the wort clearing and clumps forming before I started boil. Here's pic of buildup after rinsing boiler and it looks more caramelised than burnt like my previous buildups:
can anyone tell me what's that about the wort clearing when I left it and if that could have caused it. Anyway, continued with boil, no more issues except the pellets blocked my damn hop strainer(rolled up piece of splatter screen stuck in back of tap) and I had to pour from kettle into fermenter. 6kg grain bill in 35litres water got me 25litres at 1.06 into fermentor.
