Coffee as an amendment to raise PH is a long debunked myth.

I'm a bit confused by this. If the soil is alkaline then you would not want calcium carbonate nor dolomite, as they both neutralize acid. In other words they are alkaline.
In addition, coffee has been used to lower the pH making it more acid.
Maybe just a mix up on the scale, but FYI...
pH above 7 is alkaline/caustic.
pH below 7 is acidic.
