I’ve been mixing 0.5 grams of potassium bicarbonate in a 5 liter jug of distilled water for my espresso machine. I just use a jewelers scale to weigh it out and dump it in the jug of water. Simple. I buy the distilled water in 5 liter bottles.
I came across the rpavlis water method again and the formula to create it and got wrapped around the axle with their creation of a concentrate and then using that to make a larger batch.
Is my simple method OK?
