Various exemplary agitators for a carbonation system, systems including an agitator for a carbonation system, and methods including an agitator for a carbonation system are provided. In general, an agitator is configured to rotate in a chamber to mix together a gas, such as carbon dioxide, and a liquid, such as water, to form a carbonated fluid. The agitator includes a plurality of paddles configured to encourage the mixing of the gas and the fluid by agitating the gas and the liquid during the agitator's rotation. Each of the arms has an angled outer tip to facilitate the efficient mixing. The agitator includes a hollow shaft through which the gas is configured to flow during the agitator's rotation. The agitator can be part of a carbonation system configured to dispense the carbonated fluid as a beverage.
