KINGrinder manual grinders. The new king of value?

I note the K4 specs differ from those of the J-Max in these ways: 1) weight: JMax = 780g and K4= 630; and 2) grind size increment: JMax=8.8 microns and K4 = 16 microns (and 90 clicks per revolution in the JMax versus 60 with the K4). The 150g of extra weight in the JMax suggests (though doesn't prove) sturdier...

Bottled water mix suggestions for espresso machine

The alkalinity value of 40 is still acceptable or being exactly at the lower bound it might lead to potential corrosive issues if the mix is not always exactly 50:50?

Flow control: Can a boiler pressure gauge be used instead of a grouphead one?

The boiler pressure gauge usually reads from 0 to 3 bar, so it wouldn't be suitable for measuring brew pressure, even if you could install one at the brew chamber. The best solution for HX e61 machines would be to install a dual reading temp/pressure gauge with the appropriate ranges in the access hole (which is used for maching access...

Bottled water mix suggestions for espresso machine

Nikos is spot on. Each value in a mix needs to be multiplied by its fraction of the mix. In your bicarbonate example: HCO₃⁻ : 74 mg/L * 0.5 + 24 mg/L * 0.5 = 49 mg/L And converting that to CaCO3 equivalent, 49 * 0.82 = 40.2 The amounts of carbonate (CO₃²⁻ ), bicarbonate (HCO₃⁻ ), and carbonic acid...

Coffee roasting machine - Help needed

Kia ora, The biggest batch I've tried on my Quest M6 is 640 grams; I think it would do slightly more, but not a kilo. Have you looked at the Allio Bullet? When I bought my M6, the Bullet was also on my short list. I opted for the Quest because it is so dirt simple that anyone can easily...

Quickmill Anita - No water from grouphead.

Thanks, Nico. I pulled the gasket and shower screen and cleaned off the dispersion screw (which was filthy -- oops). Got down to the brass, and tried to get the screw off, first with a big flathead screwdriver, then with a flattened washer in a pair of vice grips (I saw this advice here on a thread); neither worked (although...
