Nature’s Perfect Shape
…for wine fermentation

Nature’s most harmonious shape is also ideal for wine fermentation. Its seamless, cornerless design allows wine to circulate freely, creating a natural, continuous stirring action you can actually observe. This motion keeps more of the cap submerged, extracting maximum fruit flavor and color—while minimizing the need for manual “punch downs.”

With a capacity of nearly 500 gallons, our egg-shaped wine tanks are thoughtfully engineered to meet the needs of both your wine and your winery. From essential features to smart extras—like custom pallets and pedestals, and easy-clean pomace doors—every detail reflects careful craftsmanship and practical insight.

Their sleek, minimalist design makes a striking impression in any showroom, yet it conceals a depth of functionality beneath the surface. Suitable for both red and white wines, each tank is hand-finished in your chosen color and can proudly display your winery’s logo—guaranteed to impress every tour.

As with all Sonoma Cast Stone products, our egg tanks exemplify exceptional design and premium concrete quality—and yes, they're hatched right here in the California Wine Country.
