A beverage nucleation device includes a housing, a beverage receiving area defined by the housing for receiving a beverage container containing a supercooled beverage, and a support configured to support the beverage container in an upright orientation in the beverage container receiving area. The beverage nucleation device may further include an applicator configured to contact a sidewall of the beverage container on the support, wherein the applicator includes an elastomeric material. An ultrasonic transducer of the beverage nucleation device is configured to generate and apply ultrasonic energy to the beverage container via the applicator so as to cause nucleation of the supercooled beverage.
