Winemaking with Chardonnay

Updated: February 2026 | Reading Time: 9 minutes

Chardonnay is the world's most popular white wine grape—and also one of the most versatile. From crisp, unoaked expressions to rich, buttery, oak-aged beauties, Chardonnay can be molded into many styles. This flexibility makes it an excellent choice for home winemakers.

Understanding Chardonnay

Chardonnay characteristics:

  • Neutral grape: Takes on character from winemaking
  • Full-bodied: Richer than most whites
  • Able to age: Especially with oak
  • Undergoes MLF: Malolactic fermentation adds buttery character

Style Decisions

Unoaked (Crisp Style)

  • Prevent malolactic fermentation
  • Ferment cool (50-55°F)
  • Stainless steel aging
  • Drink young (1-2 years)

Oaked (Buttery Style)

  • Allow malolactic fermentation
  • Age in oak 6-12 months
  • Sur lie aging with batonnage
  • Can age 3-5+ years

Fermentation

Process overview:

  1. Press grapes immediately
  2. Settle juice (cold settle)
  3. Ferment at 50-60°F (unoaked) or 55-65°F (oaked)
  4. Choose: prevent or allow MLF
  5. Age in stainless steel or oak
💡 Key Decision

Your biggest decision with Chardonnay is whether to allow malolactic fermentation. MLF creates the buttery, creamy character. Preventing MLF keeps the wine crisp and fruit-forward.

Oak Integration

Options for home winemakers:

  • Oak chips: 1-3 oz per gallon
  • Oak cubes: More surface area than chips
  • Barrels: Traditional but expensive

Conclusion

Chardonnay is uniquely rewarding because YOU shape the final style. Start with one style, then experiment.
