I figure that by the time my wife and I reach Cordoba we will be running short of the ground coffee we bring with us from the States. We normally brew a cup or two for each of us when we arise rather than immediately venturing out into the world in search of a cafe. That comes later in the day. We'd like to buy coffee from a shop that sells whole beans bulk and grinds them on the spot rather than buy packaged coffee from a supermarket. We prefer darker roasts. Advice please.
