Refined Tastes is a location-based challenge in Captain Scarlett and Her Pirate's Booty. To perform this challenge in Wurmwater, it is required to reach a weapon chest located high on the refinery supports. It is worth 4 Badass Rank.
The connection to Washburne Refinery is high top a support pylon and is accessed via two service elevator platforms with a diagonal travel. The chest is hidden on a narrow ledge half way up the support pylon, and to reach it one must jump from one of the mobile platforms when it is near the top.
Failed jumps are likely, and the task of reaching the ledge may take several attempts. There is also a pirate sand skiff that patrols in a circuit beneath the pylon that can cause trouble, so eliminating this before the jumping attempts begin removes a notable annoyance from the challenge.
