At 502 Vineyards, winemaking is deeply personal. For our family, it’s not just about producing wine—it’s about preserving the unique character of our land in every bottle. One of the ways we honor this philosophy is through natural fermentation, a process that relies on the wild yeasts from our vineyards and grape skins to craft wines that are authentic, vibrant, and alive.

Our Wild Ferment wines reflect the unpredictable beauty of nature, and while it’s a challenging process, it’s one that we embrace wholeheartedly. For us, it’s about staying true to our roots and creating wines that feel as close to the land as possible.

What is Natural Fermentation?

Natural fermentation, also called wild fermentation, is the process of letting the naturally occurring yeasts on the grapes and in the environment initiate and complete the fermentation. These wild yeasts are unique to our land in Gümüşhacıköy, carrying the specific characteristics of our terroir—the soil, climate, and even the air around us.

Unlike commercial yeasts, which are added to control the process and produce predictable results, wild yeasts create wines that are spontaneous and full of complexity. Each batch is slightly different, giving the wine a sense of individuality and authenticity that can’t be replicated.

Why Our Family Chose Wild Fermentation

For our family, natural fermentation is more than just a method—it’s an expression of trust. It’s about stepping back and allowing the grapes to tell their story without interference.

We believe that great wine doesn’t come from rushing or manipulating the process.

Instead, it comes from patience, care, and a willingness to

let nature take the lead.

Wild fermentation requires extra attention and careful monitoring, but the results are worth it: wines that are bold, layered, and truly reflective of where they come from.

How We Craft Wild Ferment Wines

The Grapes: Our Wild Ferment wines begin in the vineyard with a blend of Merzifon Karası, Merlot, and Cabernet Sauvignon, grown on 8-year-old vines in our high-altitude plots. These grapes are harvested by hand at peak ripeness to preserve their natural flavors and balance.
The Fermentation: After the harvest, the grapes are left to ferment naturally without any added yeasts or sulfites. The wild yeasts, unique to our environment, work slowly, allowing the flavors to develop organically. Fermentation can take weeks, depending on the conditions, and requires close attention to ensure the process unfolds as it should.
Aging with Care: Once fermentation is complete, the wine is aged for eight months in Hungarian oak barrels. This aging process adds structure and depth, with subtle notes of vanilla and spice complementing the wine’s natural fruit and earthy flavors.
No Additives: To maintain the purity of the wine, we avoid adding sulfites during bottling. The result is an unfiltered, vibrant wine that reflects the true character of the vineyard.

The Wild Ferment Experience

Each bottle of our Wild Ferment wine is a snapshot of the vineyard in that particular year—a reflection of the soil, the climate, and even the wildflowers that grow nearby. The flavors are bold and expressive, with layers of ripe dark fruits, earthy undertones, and a hint of spice from the oak barrels.

But what truly sets Wild Ferment apart is its vibrancy. Without the use of sulfites or commercial yeasts, the wine feels alive in a way that’s hard to describe but unmistakable in every sip. It’s a wine that tells the story of its journey, from the vine to your glass.

Why Wild Fermentation Matters

For our family, natural fermentation is a way of staying connected to the land and honoring the traditions of winemaking. It’s not the easiest path, but it’s one that feels true to who we are and what we want to share with you.

When you open a bottle of 502 Wild Ferment, you’re not just tasting wine—you’re tasting the love and care that went into nurturing the vines, the patience it took to let the process unfold naturally, and the unique character of the vineyard that year.

This is why we make wine the way we do—to share something real, something alive, and something that reflects the beauty of our home in Gümüşhacıköy.
