Low Intervention / Natural Wine

🔍 Quick Summary

Low intervention winemaking lets the grape and the place do the talking, producing wines that are raw, vibrant, and often a little wild.

🛠️ What It Is

Low intervention (or natural) winemaking is a philosophy of minimal manipulation—in the vineyard and especially in the cellar. The goal is to express the vineyard and vintage with as little interference as possible.

In practice, this usually means:

  • Native yeast fermentation (no commercial inoculation)

  • No or low sulfur additions (especially at bottling)

  • No fining or filtration

  • No additives like enzymes, color enhancers, or tannin powders

  • Minimal to no oak—often aged in neutral vessels like concrete or old barrels

While there’s no universally accepted definition, most natural winemakers avoid modern winemaking tools and chemicals, aiming instead for transparency, purity, and energy—even if that comes with some funk or unpredictability.

👅 Flavor & Style

Color

  • Often hazy or unfiltered

  • Orange wines (skin-contact whites) are common in this category

Aromas & Flavors

  • Primary: Bright fruit, herbs, citrus, wildflowers

  • Secondary: Funk, sourness, yeasty or cidery notes

  • Tertiary: Oxidized, nutty, or savory if aged with oxygen or on lees

Structure

  • Acidity: Often high and mouthwatering

  • Body: Can vary widely—light and lifted to chewy and rustic

  • Tannin: Present even in whites (from skin contact)

Common examples:

  • Skin-contact Pinot Gris from Oregon or Friuli — copper-hued and textural

  • Gamay from Beaujolais or Loire — juicy, unfiltered, and vibrant

  • Zibibbo from Sicily — floral, salty, often made with ancient methods

🎯 Why Winemakers Use It

Low intervention winemaking is about philosophy and flavor—trusting nature and embracing imperfection.

  • Flavor effects – Creates layered, sometimes surprising flavors; highlights freshness and texture

  • Structural impacts – High acid, tannic grip (even in whites), and wild textures

  • Technique variation –

    • Skin Contact: Adds grip and depth, especially in whites

    • Lees Aging: Adds body and protects wine naturally

    • Amphora or Concrete: Used to age without adding flavor

    • Zero Sulfur Wines: No SO₂ added at any stage (high risk, high reward)

Tradeoffs:

  • Stability: Wines may spoil more easily without sulfur or filtration

  • Consistency: Vintage and bottle variation can be significant

  • Flavor Tolerance: Some consumers may find them too sour, cloudy, or “funky”

At its best, low intervention wine feels alive—textural, aromatic, and emotionally engaging. At its worst, it can be volatile or flawed. But for many, that risk is part of the beauty.
