Solid Olive Castle Soaps products including soap bars, liquid soap, and a bar of soap on a wooden stand with a beige background.

Our Mission

Drawing on our roots as the original founders and team behind Buff City Soap , Brad and Jennifer Kellum set out to create something more refined: small-batch skincare and laundry essentials rooted in the purity of true Castile soap. At Solid Olive, we believe olive oil is more than an ingredient—it’s the heart of a tradition, a philosophy, and a promise. Every product we make is a celebration of craftsmanship, transparency, and timeless self-care.

From Grove to Lather: The Solid Olive Journey

Sourcing the Finest Olive Oil

We start with 100% extra virgin olive oil, rich in skin-loving antioxidants. Every batch is traceable to its source.

Cold-Processed for Purity

No heat, no chemicals, just pure, cold-processed olive oil, preserving its natural benefits.

Handcrafted in Small Batches

Blended with natural clays & essential oils, then hand-poured with care.

Slow-Cured for Over 3 Months

Aged like a fine vintage wine, creating a richer, silkier, and longer-lasting lather.
That’s why Solid Olive bars feel different from day one—and keep their shape longer.
