Cask Rack

Taken all the way down to base materials, one Cask Rack is 2 crafting steps deep and needs 4 intermediates — Brass Ingot ×7, Cedar Lumber ×7, Oak Lumber ×7 and 1 other — which resolve to 5 distinct raw materials totalling 89 units, plus 63 crystals.

That bill outweighs 13,442 of the 13,602 recipes tracked here and 1,495 of the 1,552 Carpenter ones, and 4,464 recipes nest deeper.

Only 6 of those crystals go into the final step; the other 57 are burned by the intermediates, so the real crystal cost is 36 Wind Shard, 24 Wind Crystal and 3 Ice Crystal.

The chain crosses two disciplines — Carpenter to Lv 52 and Goldsmith to Lv 23 — so no single class can finish it unaided.

All 5 raw materials are gathered, and not one of their spots is timed, so nothing in the tree waits on the Eorzean clock.

Of the intermediates, Silver Ingot has the widest use: 157 recipes call for it, spanning eight of the eight crafting classes.
