Select your peaches for ripening. Choose large, fully colored and unbruised peaches for best results. Store the other peaches in the refrigerator for slower ripening.
Place peaches between two linen napkins, in a safe, shaded spot in the kitchen. Allow four to seven days for natural ripening with this process.
Place two to three peaches in a paper bag. Leave the bag open and sitting on the counter, in a shaded place in the kitchen. Check for ripeness in two to three days with this method. Never put too many peaches in the bag, as touching peaches rot with this method.
Test for ripeness. Ripe peaches smell strongly of peach and depress slightly to the thumb. Don't press hard enough to squish the peaches, as this bruises and damages the flesh.
