Darker-colored jeans are not only a fashion statement, they also help elongate the legs and make a person appear thinner. Unfortunately, even the darkest pair of jeans will begin to fade after several washes. Dying your light-colored or faded jeans is possible with a widely consumed beverage you may already have in your pantry. Coffee, along with tea and red wine, contains tannic acid, which will darken the color of your jeans to a desired hue.
Save your used coffee grounds until you have 2 cups of used grounds. Drink a darker roast during this time to ensure that you have a darker coffee dye for your jeans.
Pour the coffee grounds and 1 gallon of water into a large cooking pot.
Bring the coffee grounds water to a boil over high heat. Allow the mixture to boil for five minutes before removing the pot from the heat and allowing the coffee mixture to cool until it reaches room temperature.
Lower the jeans into the mixture. Push them to the bottom of the pot with a gloved hand or wooden spoon and hold them down for 30 seconds. This will ensure that all of the jeans are covered with the liquid.
Allow the jeans to remain in the coffee bath for at least eight hours. The longer the jeans remain in the coffee, the darker the stain will be.
Remove the jeans from the coffee bath and rinse them briefly under a cool tap. This will remove some of the lingering coffee odor and excess dye.
Lay the jeans onto a towel or hang them up outside and allow them to dry.
