Kahlua recommends storing Mudslide for no longer than 1 year after production. Unlike the original liqueur, Mudslide can actually curdle or mold because of its dairy content. Once the bottle has been opened, the lid should be kept sealed as much as possible and any leftovers should be refrigerated.
