Returning Nutrients to the Vineyard: Building Healthy Soils Naturally
At Iron Hub Winery & Distillery, sustainability starts in the vineyard. In a recent vineyard update, winemaker Spencer Jones shared one of his happy activities of the growing season: returning nutrients to the soil naturally. “Honestly, this is one of my favorite parts: putting it back into the soil.”
After harvest and pressing, the leftover grape skins and pumice still contain valuable nutrients. Rather than discarding them, Spencer and the team spread the material back into the vineyard to replenish the soil and support long-term vine health.
“These pumice skins right here are full of nutrients,” Spencer explains. “So, we’re building back what these vines took out of the soil, replenishing our soils naturally, and then seeding over it with our cover crop.”
Over time, the organic material breaks down and becomes part of the soil, improving soil structure and naturally returning nutrients to the vines.
“In six months, all this will have decayed into organic material,” Spencer says. “That will slowly replenish our soils with nutrients, resulting in a sustainable vineyard.”
These regenerative farming practices are integral to Iron Hub’s approach to vineyard stewardship. When combined with seasonal cover crops and thoughtful farming techniques, they help create healthier soils, balanced vines, and wines that truly reflect the Sierra Foothills.
At Iron Hub, sustainability is more than a philosophy — it’s part of daily work in our vineyard year-round, helping preserve the land for future generations.
