Re: Ro or tap

I've tested several lots of CaCl2 in my day, and it has been my experience that it is never anhydrous. 94%-96% pure when first opened is about as good as it gets, and it goes down hill from there as it absorbs moisture from contact with air. Put calcium chloride flakes in the oven at 150C until the...

Re: Ro or tap

I've sent off the water sample today. I'll post results when I get them and see where we go from there... Did you keep a sample of the water you sent for yourself? For PeeBee, I notice you have spent time on the British Geological Survey website, but did you come across this page? It takes a bit of...

Re: Ro or tap

Again, I didn't realise when I decided on that recipe all the things I might/should consider. I am grateful for all the advice and will use it for sure! Maybe I could post wallybrews analysis and you could confirm your thoughts in due course? I will have a look at Bru'n Water and see if I can rough...

Re: Ro or tap

Yes, that recipe is unlikely to have been created with British malts and water profile in mind.

Re: Ro or tap

I appreciate any help! 👍 The importance of water treatment should never be berated or undervalued. While it is virtually always possible to make a drinkable beer with the water supplied to your home untreated, the chances of that water having the perfect mineral content for the beer of your choice ...

Re: Ro or tap

That was to get the right number of zeros after the four. :wink:

Anyway, having water with alkalinity equivalent to 255mg/L CaCO3 makes water treatment simple for brewing stouts.

Re: Ro or tap

1.399972? Call it 1.40?

1/(1-1/3.5) using fractions.....
=1/(1-2/7)
=1/(7/7-2/7)
=1/(5/7)
=7/5
=1+(2/5)
=1.400000000


Bloody calculators.

Re: Ro or tap

Indeed it is excellent, and there is undeniably nothing else like it, but it has a serious Achilles heel. It relies heavily upon calcium carbonate, and it presumes that calcium carbonate both fully dissolves and dissociates into ions, just as for other calcium species such as gypsum and calcium chl...

Re: 12 Days and Still Going

Tape the Inbird Sensor to the fv with bubble wrap covering it. The vial of steriliser will have a different thermal mass to your full fv. Indeed it will. which way and with what effect is the unknown. WLP002 is a well respected yeast, particularly its ability to flocculate. I would certainly give i...

Re: 12 Days and Still Going

No, you won't have overpitched, but it ought to have been at FG by now. Checking your hydrometer in tapwater should be enough to find if it might be out by much for measuring atowards the end of primary fermentation. What yeast, original gravity and temperatures? Sounds as if it might need rousing a...

Re: Ro or tap

Without having a sample of your water analysed you will, forever, either be in doubt, denial or both of those. That said, if your water is as soft as it appears, any errors or deviations from the norm should be inconsequential. If you don't already have one, I would advise you buy a cheap TDS meter ...

Re: First Attempt at adjusting Water Profile

NEIPA is an American homebrew style and therefore one might assume the desired brew liquor will conform with American homebrew's understanding and beliefs. Those differ to British understanding and beliefs. Assuming you have correctly replicate the required water profile it may not be impossible to ...

Re: New pH probe--help!!

Assuming both probes are similar to the one I bought some time since, the storage holder is very small and will soon dry if it not properly tightened or there is spillage. I would hope and expect after a good soak in storage solution the probe should be fine. My replacement has lasted much longer th...

Re: New pH probe--help!!

A pH probe is usually stored in a near saturated solution of potassium chloride and suggest in your case the water has evaporated to leave those crystals. Potassium chloride solution is also that inside the probe and as you correctly assume, is topped when necessary using the syringe through that ho...

Re: Graham's water treatment calculator

Brewing Elements Water has it around there too at 600ppm. Pretty heavy however so unless you’re brewing historic beers my taste is personally at at least half that. At work for the basic pale I’m at a much more sensible 3:1 with 150/60ppm and it’s much nicer. On several occasions I've brewed near t...
