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. As founders, we — Karen & Mark — set out to create a space where the absence of alcohol wouldn’t mean the absence of beauty, pleasure, or connection. What began as a personal shift has become a larger vision for how we experience life with intention.

Curation with Integrity

We believe in less noise, more meaning. 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. It’s not about substitution; it’s about presence.

A Place to Discover


Our flagship store, opening in South Florida in 2025, will reflect this philosophy. Part tasting bar, part atelier of discovery, it’s a place where design and flavor meet. Through seasonal edits, elevated service, and a slow, thoughtful rhythm, we invite guests to engage with the ritual of zero-proof drinking in a way that feels elegant, modern, and deeply human.

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.

A Shared Standard


We created Rienne to live well — fully, beautifully, and without pretense. This story is personal, but it’s not just ours. It’s for anyone choosing intention over habit, and seeking pleasure in what is thoughtfully made. We’re honored to be part of a quiet revolution — one sip, one setting, one shared moment at a time.
