Chop 22 oz. of Goat Milk Melt and Pour Soap Base into small uniform pieces. Place the soap into a heat-safe container and melt in the microwave using 30-60 second bursts.
Add 1 tsp. of coffee seed oil (about 0.1 oz.) to the melted base and use a spoon to thoroughly mix in. Add 0.4 oz. of Espresso Fragrance Oil and 0.4 oz. of Vanilla Color Stabilizer and mix.
Add 1 heaping tsp. of the used coffee grounds and stir in.
Allow the soap to cool to about 120-125 degrees F. That prevents the coffee grounds from sinking to the bottom of the bars.
Fill each mold cavity. After each pour, spritz the soap with 99% isopropyl alcohol to help get rid of bubbles. Allow the soap to cool and fully harden for several hours or up to overnight. Remove from the mold and enjoy. To prevent glycerin dew, wrap each bar in plastic wrap.
