Minimal Intervention,
Maximum Expression.

The mechanics differ slightly between red and white winemaking, but the principle is the same. For our whites, free-run juice drains from the press under the weight of the grapes alone, before mechanical pressure is applied. For our reds, it drains from the fermenter after fermentation is complete, released by gravity as the wine separates from the skins. In both cases, what emerges first — without force — is considered the most elegant and expressive fraction of the harvest.

The analogy most people reach for is extra-virgin olive oil: the first cold press, before heat or pressure extracts the remaining oil from the paste. Drip sake works the same way. In each case, the first liquid released naturally carries the clearest expression of the source material.

What pressing adds — and why we don't need it

Free-run typically accounts for roughly 70% of a wine's total potential volume. The remaining 30% is locked within the skins and seeds, recoverable only through mechanical pressing. That press fraction yields additional wine, but it also extracts more tannins, phenolics, and coarser compounds from the grape solids. Used judiciously, press wine can add structure. Used without restraint, it introduces bitterness, heavier aromatics, and textures that work against finesse.

Many serious producers keep the two fractions separate throughout the winemaking process, evaluating each before deciding whether any press wine earns its place in the final blend. At Ojai Mountain, we make that decision earlier: we bottle only the free-run. The reasoning is rooted in the vineyard itself. At elevation, with thin soils, strong winds, and a short growing season, our vines produce small, thick-skinned berries with a naturally high skin-to-juice ratio. Concentration, structure, and tannin are already present in abundance. Pressing would not refine the wine — it would add weight where precision already exists.

Choosing to bottle only the free-run fraction means sacrificing roughly 30% of potential production. What remains is wine with finer texture, greater aromatic clarity, and a more transparent connection to the mountain where it was grown.

Red Wine Fermentation

Fermentation is initiated by the native yeasts naturally present on the grape skins and in the winery environment rather than by adding commercial yeast strains at the outset. Native fermentations are slower and less predictable than inoculated fermentations, but they tend to produce wines with greater aromatic complexity and a more faithful expression of the vineyard site.

At the same time, minimal intervention does not mean refusing to act when stability is at risk. A “stuck fermentation” occurs when yeast stops converting sugar into alcohol before fermentation is complete, leaving residual sugar that can create microbial instability, unwanted refermentation, or spoilage in bottle. Erich monitors every fermentation closely, and if a native fermentation appears at risk of stopping prematurely, commercial yeast may be introduced to safely finish the process. The goal is always to preserve both site expression and the long-term integrity of the wine. Sulfur use remains limited throughout.

White Wine Fermentation

Our white wines are made with a focus on preserving freshness, natural acidity, and site expression. After primary fermentation, we add a small amount of sulfur dioxide to prevent malolactic fermentation, a secondary bacterial conversion that softens acidity and can create richer, buttery characteristics. By blocking this process, we retain the bright citrus, mineral tension, and energetic structure that define our high-elevation vineyard. The result is a style that feels precise and lifted, with clarity, texture, and a strong sense of place shaped by cool mountain nights, ocean influence, and restrained winemaking.

At the Winery

At the winery, fruit is carefully sorted before processing. All red varieties are fully destemmed prior to fermentation. To date, we have not used whole-cluster fermentation, though this is not a philosophical position. Destemming allows us to work with clean, ripe fruit and gives us precise control over tannin structure and extraction from the outset, which has been especially important during the earlier years of understanding the vineyard site.

Once fermentation is complete, our red wines move into neutral French oak barrels, where they age for 18 to 24 months before bottling. Neutral oak plays a specific role here: it allows the wine to breathe and integrate slowly over time without contributing oak flavor, vanilla, or toast. The goal is a wine that feels polished and complete without tasting like the barrel it aged in.

The extended aging period is not arbitrary. At this elevation, our reds have the structure and acidity to develop in barrel without losing freshness. The extra time allows tannins to soften, flavors to deepen, and the wine to find its balance on its own terms.

Reds — Unfiltered and Unfined

Our red wines are bottled without fining or filtration. Fining agents — such as egg white, bentonite, or isinglass — are commonly used to clarify wine and remove certain proteins or tannins. Filtration removes particles and can extend shelf life. We skip both.

The reason is rooted in red wine chemistry. Red wines contain substantial tannin and phenolic material from skins and seeds. These compounds naturally bind with proteins and other suspended particles over time, forming sediment that settles in bottle. Reds also have structural buffering against microbial instability that whites lack. Because of that, a lightly cloudy or sedimented red is widely accepted — especially in minimal-intervention wines — and poses no risk to the wine's integrity.

By skipping fining and filtration, we preserve the texture, weight, and complexity-building compounds that give our reds their depth and aging potential. Our wines may show natural sediment over time. That is not a flaw. It is evidence that nothing has been taken out.

Whites — Filtered for Stability, Not for Style

Our white wines are filtered before bottling, but this choice reflects the chemistry of white wine itself, not a departure from our minimal-intervention approach. White wines contain far fewer tannins and phenolic compounds than reds. Without those natural stabilizers, proteins remain suspended more easily, making whites prone to visible haze, protein instability, and microbial spoilage in bottle — even when the wine is technically sound.

A gentle filtration removes unstable particles and microbes while preserving the aromatics and texture that define our high-elevation whites. For wines made without malolactic fermentation and with minimal sulfur, this filtration supports long-term stability and allows the wine to evolve cleanly over a decade or more.

The result is a white wine that tastes exactly like Ojai Mountain — precise, mineral, energetic — without the risk of instability that would undermine that expression over time.
