WHAT MAKES MARIANNE’S UNIQUE
Marianne’s stands apart in the crowded oils and fats category by pairing five generations of agricultural and ingredients expertise with an uncompromising commitment to purity, transparency, and craftsmanship. Unlike many competitors who simply source and bottle finished oils, Marianne’s oversees the entire process from farm to bottle, working directly with multi-generational and smallholder farmers for their avocado oil across Mexico, South America, East Africa, and for their beef tallow across the U.S. Marianne’s avocado oil is refined with care using a controlled, low-temperature process that helps retain naturally occurring nutrients while reducing processing-related contaminants. Marianne's beef tallow is rendered slowly in small batches, gently releasing moisture and impurities to create a clean, concentrated fat with a rich texture and exceptional cooking performance. Every batch of avocado oil and beef tallow is refined or rendered “low and slow” to preserve nutrients while minimizing harmful processing contaminants, then rigorously tested and verified through third-party labs.
This purity-first approach has earned Marianne’s rare distinctions, including recognition as one of only two brands to test 100% pure in a landmark UC Davis avocado oil study, along with Clean Label Project Purity Awards and Seed Oil Free Certified®. From introducing the first refined Regenerative Organic Certified® avocado oils to hit grocery shelves to re-elevating traditional beef tallow through responsible sourcing and small-batch rendering, Marianne’s isn’t reinventing pantry staples — it’s restoring them to what they were always meant to be: honest, nourishing, and made with care.
