AWasteofCoffee Espresso (95 TDS)
๐งช Concentrate recipe
MgSO4 (Epsom Salt)
- 7.39g/300mlNaHCO3 (Sodium Bicarb)
- 5.03g/300ml
๐ฅ Per liter brew water
MgSO4 (Epsom Salt)
- 5.5ml (55 ppm)NaHCO3 (Sodium Bicarb)
- 3.5ml (35 ppm)
The concentrates above are added to my Coway R.O. water which has a very low TDS of 3.5 ppm. I choose to use this recipe as it seems to be a good balance - not too low TDS to corrode the boiler while at the same time not too high to scale.
