Nuka Mixer

"Nuka Mixer" is an unmarked repeatable side quest in Washington's Malevolence that is available immediately after talking to Vault 89 Overseer Rachel O'Connolly for the first time during Old Runners.

The player asks Rachel why there is so much Nuka-Cola merchandise all over her office, prompting her to explain to the player that she is able to make Nuka-Cola in the vault using the purified water (explaining why none of the Nuka-Cola in Vault 89 is irradiated).

Rachel had reverse engineered the formula using the vault's research equipment; however, due to lack of ingredients, she had to take liberties with the ingredients that actually goes into the vault's own Nuka-Cola; regardless, the vault's cola tastes exactly as the original does. (The player then has the option of either continuing the conversation or mentioning Sierra Petrovita of Girdershade, prompting Rachel to call her a psycho bitch with a two-person fan club).

The player then asks Rachel if she can make a batch for them; she gladly agrees, and hands the player a list of ingredients she is able to use to craft custom Nuka-Cola batches with different flavors.

If the player brings her an ingredient, they are given three bottles worth of the custom Nuka-Cola.

The ingredients the player is told about are fresh apples, carrots, pears, and Mutfruit. The player also has the option of bringing Rachel other ingredients that are not marked, which are whiskey, blood packs, Mentats, and the Alien biogel found in Mothership Zeta.
