• and
• a cap attached to the pod, wherein the cap includes a retainer with a cut-out portion creating one or more flaps on the retainer that fold with pressure thereby breaking the seal and releasing the first beverage ingredient and the second beverage ingredient.

• a first beverage ingredient disposed in the first chamber;
• a second beverage ingredient disposed in the second chamber, wherein the second beverage ingredient is different from the first beverage ingredient;
• and
• a cap attached to a top of the pod, wherein the cap includes a retainer sealed on one of either the cap or the top of the pod, wherein the retainer includes a cut-out portion creating flaps on the retainer that fold with pressure to thereby break the seal and release the first beverage ingredient and the second beverage ingredient into a mixing liquid, and wherein when the beverage ingredients mix with the mixing liquid, a beverage is created.
