The stainless steel mini pellets help to prevent sediments in carafes and decanters. Directions: Fill with plenty of water, carefully add the pellets and swirl the container for 1-2 minutes. Pour out carefully into a sieve and simply rinse the pellets with water. Used correctly, the bottle cleaner can be reused indefinitely! From a simple wine glass to a glass which is a pleasure to drink from: every Riedels collection arises out of sensory workshops designed to engage all the senses.
