Thai Water Chemistry - Bottled and RO

Postby onesnzeros » Tue Jun 28, 2016 9:33 pm

Has anyone here sent off their water to get tested yet?
Where can i send it to? How much is it?
I want to get my water chemistry mapped, even if i can get an average of say three different sources of RO water, find out what these machines are leaving behind… from time to time i'm assuming i get a bottle from a machine with a worn out membrane and my salt additions are way out of the ballpark… ok if it's a feckin huge double IPA, but i'm really doing my best to pull together some consistent and pale pale pale ales. Very frustrating from time to time. The mash pH is fine, but i just wanna get an idea of what these RO machines are leaving behind.

Also, on topic ish… I need to find some buffer solution to calibrate my pH meter.
I've found this…

and this…

has anyone dealt with these companies before? or know where i can get bulk packets? 350 baht for 2 packets is just INSANE :(

Great post and that's interesting about the Nestle and Minere as I've been looking for this info. Also would love to know where I could get water tested. It makes a big difference to beer but it's something I've just ignored due to lack of known places to test. Please feedback if you find anywhere.

i just buy the reverse osmosis stuff now, depending on the style of beer - a few grams of calcium chloride and calcium sulphate are plenty. Maybe a pinch of iodine, a smidge of epsom salts. But the calcium is enough most of the time. If you're doing dark beers, it's possible the mash pH could drop a bit low with this type of profile. Minere is high in carbonates which can help the darker mashes - in this case i generally use 1 x 6L minere and mix it with my adjusted water. I haven't been doing many darker beers, so I haven't needed chalk or baking soda yet. I have a good pH meter that seems to be enough, but the calibration is out i know, i need to find some buffer solution, gotta find a pool shop or something.

I've since discovered it's possible to get water tested at your local water authority, not sure how much it is yet though. Give me a few weeks, maybe plus a few more (i'm on Thai time, and a teacher salary :( )

Yeah let me know how that goes. I sent my water to the university in Nan where our farm is to get it tested. If all else fails I can send yours up there if you can get me a sample

yeah cheers, i'm really just (for now) interested in what the RO machines are leaving behind. On average i guess… everything is so dodgey here, i guess i'm happy enough to have ALE really :P mai bpen rain, allay goday… i think i'm turning Thai-nese, i really think so :P

Hi all,

I've been using Sprinkle Water plus my own salt additions cos I always assumed it was stripped of everything (http://www.sprinkle-th.com/en/production.php). Might this not be the case?

yeah from the blurb it should be.
i'd give it a go with a pH tester.
