About RIENNE

Philosophy

A Shift in Perspective RIENNE was born from a quiet conviction: that refinement, clarity, and wellbeing belong at the center of how we gather, sip, and celebrate. What began as a personal shift has become a larger vision for how we experience life with intention.

The RIENNE Standard


Curation with Integrity

Every bottle we curate is chosen for its integrity — crafted with care, rooted in sustainability, and designed to stand on its own. Our selections don’t mimic; they express. This is Liquid Gastronomy™: a sensorial ritual that reflects the season, the table, the mood.

Beyond the Glass

Rienne serves across three touchpoints —retail, eCommerce, and hospitality partnerships — all informed by the same point of view. We collaborate with restaurants, hoteliers, and vision-aligned creators who believe that wellness and sophistication can exist in the same breath. There’s no compromise here — only a new lens through which to see the possibilities.

Flagship store


A Place to Discover — Our flagship store, opening in historic Coral Gables in 2026, will embody this philosophy. Part tasting bar, part atelier of discovery, it’s a space where design and flavor meet — through seasonal edits, elevated service, and a slow, thoughtful rhythm.
