pH too high?

Post #1 made 3 years ago
I've just had my tap water tested at an aquarium shop and it came up with pH 8.1. I read somewhere that the ideal pH is 5.6 (ish?). I live in Pembrokeshire, South Wales and believe the water to be soft (little limescale build up in kettles, etc). Should i treat my brewing water and if so with what?

Thanks all,
James

James, you have nothing to worry about here.

8.1 is quite normal for starting water. Once you add your crushed grains to it, it will drop down to a much lower pH.

For a new brewer (and many existing/experienced brewers), you do not need to worry about water chemistry to produce a great beer and, if you are lucky, a perfect beer. You quoted 5.6 above. This is actually incorrect for many styles and situations. And, to tell you the truth, I have never seen any 'perfect' or anywhere near perfect maths/logic on this pH area.

To be sure you are in the ball-park though, buy some pH strips and check your full volume mash a few minutes after you add your grain/grist and maybe ten minutes after again.

That should be your first step into water chemistry I think. I also think that if your mash pH is somewhere between 5 and 6 then you have more important things to worry about if your beer is not tasting great. For example, the recipe itself.

There's some weird things about pH paper that I should have mentioned above sorry. Basically there are two different types. Suss out pH strips in this thread. Hopefully your ones are also the right type Dave :peace:.

Thanks to brewdave I have just order 10 strips to trial.

Pat - they are advertised as suitable for wort in as much as they show...

Can compare to my digital pH meter, but will probably never get around to it!

On your next order, consider buying the 5m roll mentioned here. Whilst the strips above are correct for wort, a roll will give you over 150 tests and the gradations and paper are more precise and easier to read.

When do order a roll, try and remember to click on the Amazon banner at top of the page. We have had it going for 19 months now but have only just cracked $100.

:lol:.

I seem to remember those particular ones are either difficult to source in the UK, or are very expensive.
Maybe Bob needs to add these to his "cheese" winners awards!
