"Would you care for a refill?" This question should always be answered affirmatively when discussing wine or room diffuser capsules. These luxe little cocoons are filled with The Kimpton Scent — citrus, green tea, black pepper, clove and musk. Each refill lasts about 300 hours when used with the Kimpton Room Diffuser Set. You’re on your own for the Pinot top-off. Diffusers sold separately.
