1In each canning jar, place one color candies. Pour 1 cup (8 oz) vodka over candy in each jar, making sure candy is completely covered with vodka. Place lids on jars; seal tightly. Shake each jar vigorously 20 seconds. Let stand 3 hours.
2Filter each candy-infused vodka through 1 coffee filter placed over 2-cup glass measuring cup. (This can be a slow process due to the build up of sugar from the candy. It may be necessary to poke a few small holes into the coffee filter for an initial filtration.) Repeat process with a second coffee filter. If after the second filtration a sugar residue remains, filter again or skim with a spoon.
3Carefully pour each infused vodka into separate flask. (If necessary, use funnel.) Refrigerate until ready to use; refrigerate up to 6 months.
