pH of 5. This answers is correct assuming you brew your coffee with distilled water or "pure water" as it can be referred to. However most, if not all, municipal water and some rural water systems have acidic water that comes out of the tap. even if you filter this water there may still be some residual acidic properties. Normal black coffee tends to have a pH in the range of 4.3 to 5.0
Bases taste bitter and acids taste sour, so coffee would be a base.
ANSWER:Black coffee and even the coffee grounds can be added to the soil to increase the Ph of the soil. Certain plants will grow sluggishly in low pH. One of these is the Azalea. They like high pH soil and oak leaves and/or coffee/coffee grounds added to the soil or just placed on top of the ground will do this.
