Brew day testing equipment

While Beer is 90-97% water, it is a very tricky subject.

Brew day testing equipment

Postby AFewTooMany » Fri Aug 07, 2015 09:27

I've recently delved into the nightmare that is water treatment and got a alkalinity salifert kit. I'll be using it to test my untreated water on each brew day and retesting after treatment.

My question is do I need an additional testing method such as a digital ph meter for the mash/boil/fermenter? Or is this even necessary?

I just use the Salifert kit. Testing pH can be done in the mash to see if it's converted before sparging. If your planning on getting a pH meter get a decent one. I don't bother testing pH though

I bought a cheap pH meter just to confirm the figures and it worked out OK.
I use BruNwater for water adjustments.

It doesn't have to be a nightmare as long as you apply the KISS Principle :D

The first step in the KISS guide to water treatment is to measure your alkalinity. once you know that you can determine if there is any need to reduce it with acid, or increase it using sodium/potassium bicarbonate. As you are Glasgow based I will bet that you have very low levels of anything in your water, and therefore you will be adding minerals. A tsp of gypsum in the mash and one in the boil will be good for starters.

Need no. What it would tell you would be that your water treatment 'helps' the mash pH fall in the right range . . . although even with no water treatment and your water the vast majority of mashes will fall in the right range anyway. It would also enable you to determine the effective treatment for your liquor for the beer styles you want to brew, if you want to put the time in doing test mashes.

pH has absolutely nothing to do with degree of conversion, it will tell you if the pH is in an 'optimal range' for conversion but cannot measure conversion. :roll:

Sounds like it was a good value meter rather than a cheap one :D

It's good to hear it works when the water has a lot of minerals in it, but it does not work for me with a significantly lower level of minerals present (but plenty of cryptosporidia), and it is even less accurate with my full volume mashes on the Braumeister. I also think the 'warnings' regarding chloride and sulphate levels are unnecessary. You can brew great beer with high levels of calcium sulphate and chloride, brewers have been doing it for years . . . and that applies to world beer styles not just those British (or even UK ) ones. . . . Unless of course you are deliberately trying to brew a beer with no flavour :twisted:
