How does Indri differ from Bourbon despite sharing vanilla notes from its American cask component?

It layers vanilla notes with complexity from European oak and PX sherry influence, creating a fruitier experience

While the American cask component in Indri Trini maturation likely imparts vanilla notes similar to those found in Bourbon (which requires new charred oak), Indri diverges significantly through its use of additional cask types. Specifically, the inclusion of European oak and PX sherry casks layers richness and complexity onto the base sweetness. This layering results in a profile that incorporates dark fruit and raisiny notes, making the resulting flavor profile significantly fruitier and more intricate than the typically purer, sweet profile derived predominantly from new charred oak maturation seen in many Bourbons.
