Adding minerals post brew

just to add, pure distilled is bad for an espresso machine no?

Cuprajake Yes, do not put 0TDS water in your coffee machines (espresso, or otherwise).

Petre adding drops of 10000ppm only made the shot worst. But next batch of water will be 40/20 and lower and hope I get better results.

Should you be brewing in the espresso machine with 20ppm alkalinity?

10,000ppm sounds like a typo?

If 1 drop of Lotus alkalinity (KH) is 10ppm in 450mL then 1 drop will be around 113ppm in 40mL and not practical for espresso.

Cuprajake so can we now buy cheap beans and cheap grinders, produce $hit shots and add water post to make them taste good? sweet im in,

No, it just tweaks perceived acidity, in the same way brewing with different water does, it just let’s you brew with a ‘clean slate’ and dial in the acidity by taste, or find a value you like if preparing a new batch of water.

i was being cheeky - its alot of messing about dont you think?

i use the dr pavliss water as he believed it added nothing to the taste of the coffee

Cuprajake I know, but what water makes coffee taste just like coffee within influence of water? None of it, because coffee is made with water and there is no known neutral state (other than 0TDS and that is very, very far from normal and is more one end of the spectrum rather than neutral).

For me with espresso it’s a trade off, I trade off some possible taste? For boiler safe water which will never scale, I’m happy with the espresso I make, don’t feel like it’s missing anything post brew, this gets into the realms of refractometer and faff

Yes I have one, but rarely use it haha

This is no faff, it’s a drop or two in your 450mL/225mL of coffee, it doesn’t seemingly have any application for espresso.

So you are using 0TDS water? I’m confused now.

Cuprajake no I use rodi with potassium bicarbonate, for espresso

That’s what they’re doing, basically. They don’t need the alkalinity to protect a kettle so much, but add the drops/KH after brewing, you add it before brewing. They’re adding GH too, but you don’t need to, nor do you need to use 4 different drops. It’s easier to dose than sodium bicarb is to RODI water, no scales needed.

There’s no more/less need to test run than you have now.

Do most people who do pour over use distilled water?

Cuprajake I use Osmio Zero - mineralised.

Cuprajake I shouldn’t think so, I use Lockhills, or Zero jug water remineralised with tap water, or BWT mg2 filtered water, depending on what’s around at the time. But if I stuck to Zero jug, these drops are not something I’d rule out, saves mixing/measuring (depending on price/availability, they seem a whole lot more practical than say Third Wave Water).

I don’t think it any more/less practical overall that what you, or I basically do, unless for experimenting/tweaking on the fly, where it’s quicker & more convenient for small batches.

$60 I believe they cost.

I make all mine in a big batch so it’s only a once a month thing

I don’t do as much brewing now, lock down did have it’s plus points haha

Cuprajake

Profit margins on this stuff is putting Weber to shame. I’d be surprised if you couldn’t buy a kilo of the salts, bottles with pipettes, and 5 litres of distilled water for significantly less than $60.

Rob1 - you wouldn’t guess what I did yesterday… 🤣🤣🤣🤣🤣🤣🤣

Enough bottles and salts for me and friends, for a lifetime, from Amazon for £20. 🤣🤣🤣🤣🤣

Yeah I’d also make my own, there basic and you can buy good quality salts from intralabs etc

I used to make all my own salts for reef dosing.
