Natural Brunello Production Guide - Evidence-Based Protocols for Minimal Intervention
11 August 2025
Executive Summary
This guide provides scientifically-validated protocols for producing exceptional natural Brunello di Montalcino through absolute minimal intervention. Each recommendation is calibrated for:
- 100% Sangiovese as required by Brunello DOCG regulations
- Minimum 2 years oak + 4 months bottle aging (5 years total for Riserva)
- Galestro soil conditions at 300m elevation
- Ultra-low sulfur philosophy (10ppm at crush only)
- 12-year spontaneous fermentation heritage
All protocols meet or exceed the strictest natural wine standards globally, ensuring your wines could qualify for any certification while focusing on quality over bureaucracy.
Section 1: Mycorrhizal Network Cultivation for Sangiovese on Galestro
Scientific Foundation
Arbuscular mycorrhizal fungi (AMF) colonization specifically benefits Sangiovese cultivation. Research on Sangiovese vines demonstrates that Funneliformis mosseae inoculation increases volatile organic compounds crucial for wine quality¹. In Mediterranean climates similar to Montalcino, AMF colonization provides 40% improvement in water stress tolerance - critical for Sangiovese's tendency toward high vigor².
Galestro's friable clay-schist structure with pH 7.5-8.0 provides ideal conditions for mycorrhizal establishment, as demonstrated in Chianti Classico studies³.
Implementation Protocol for Brunello Vineyards
Year 1 - Initial Inoculation (Specific to Your Parcels):
30-year-old vines (established):
- Apply 25g/vine of native AMF inoculum in March
- Focus on Rhizoglomus intraradices for mature vine disease resistance
- Expected colonization: 40-50% within 6 months
- No soil disturbance deeper than 10cm to preserve networks
10-year-old vines (developing):
- Apply 35g/vine targeting 60% colonization
- Mix F. mosseae and R. intraradices equally
- Critical for quality improvement during peak production years
- Monitor monthly using gridline intersect method
6-year-old vines (young):
- Apply 50g/vine for rapid network establishment
- Young vines respond fastest to inoculation
- Avoid phosphorus fertilization which inhibits colonization
March replanting protocol:
- Pre-inoculate roots with 100g AMF mix per vine
- Ensure galestro soil temperature >10°C at planting
- Plant material must be from massal selection, not clonal
- Water only with non-chlorinated water first season
Expected Outcomes for Brunello Production
- Enhanced Sangiovese aromatics (specifically cherry and violet notes)
- Improved tannin polymerization during mandatory 2+ year aging
- Natural protection against esca and grapevine trunk diseases
- 30-40% reduced irrigation needs preserving Brunello typicity
- Increased wine complexity measurable after 18 months aging
Section 2: Indigenous Yeast Optimization for Long-Aging Wines
Scientific Foundation
Brunello's extended aging requires robust fermentation to prevent volatile acidity development. Research from Montalcino shows indigenous Saccharomyces cerevisiae populations produce 23% higher glycerol content than commercial yeasts, crucial for Brunello's texture after 2+ years aging⁴. Natural fermentation produces higher levels of mannoproteins that stabilize color during extended oak aging - essential when working with only 10ppm SO2⁵.
Implementation Protocol for Brunello Fermentation
Pied de cuve preparation (Brunello-specific):
- Timing: Start 5 days before each parcel's harvest
- Selection: 100kg best Sangiovese from oldest vines
- Crushing: By foot or gentle roller, no destemming
- Temperature: Maintain 22°C (optimal for Sangiovese indigenous yeasts)
- Monitoring: Check every 8 hours - pH, Brix, sensory
- Readiness indicators:
- 3-4° Brix drop achieved
- VA <0.3 g/L (critical threshold)
- Active bubbling visible
- Clean fermentation aroma (no H2S)
Fermentation management for age-worthy structure:
- Days 1-3: 20°C to preserve Sangiovese's delicate fruit
- Days 4-12: 26°C maximum (higher destroys aging potential)
- Days 13-25: 24°C for gentle tannin polymerization
- Days 26-35: 22°C extended maceration for structure
- Total maceration: 30-35 days for Brunello requirements
Critical parameters for 10ppm SO2 protocol:
- pH must remain <3.5 throughout (measure daily)
- Temperature control essential - no spikes above 28°C ever
- Dissolved oxygen <2mg/L during active fermentation
- Complete MLF within 60 days to minimize VA risk
- No additions except 10ppm SO2 at crush
Risk Mitigation for Extended Aging
- Maintain three separate pied de cuve from different parcels
- Monitor VA every 48 hours during fermentation
- If VA exceeds 0.4 g/L, cool to 18°C immediately
- Never exceed 0.6 g/L VA (wine becomes unmarketable)
- Keep detailed fermentation charts for each tank
Section 3: Whole Cluster Adaptation for Brunello DOCG
Scientific Foundation
While Burgundy successfully uses 30-100% whole clusters, Sangiovese's different phenolic structure requires careful adaptation. Research from Tuscany shows 15-20% whole cluster inclusion optimal for Sangiovese, providing complexity without excessive tannins that become aggressive during extended aging⁶. Stem lignification in Sangiovese occurs 2-3 weeks later than Pinot Noir, requiring patience⁷.
Brunello-Specific Whole Cluster Protocol
Maximum whole cluster percentage by vine age:
- 30-year vines: 20% maximum (best stem maturity)
- 10-year vines: 15% maximum
- 6-year vines: 10% maximum (younger vines = greener stems)
- Never exceed these percentages for Sangiovese
Sangiovese stem assessment (September):
- Visual: 90%+ brown coloration (vs 80% for Pinot)
- Physical: Stems snap cleanly, no bending
- Aromatic: No green/vegetal aroma when chewed
- Timing: Usually 7-10 days after optimal berry ripeness
Fermentation adjustments for whole cluster Brunello:
- Layer whole clusters in middle third of fermenter only
- Extended cold soak: 72 hours at 12°C (longer than Burgundy)
- CO2 blanket essential during cold soak
- First punch-down only after 5 days (preserve whole berries)
- Gentle extractions - 2 punch-downs daily maximum
- Total maceration: 30-35 days for structure
Impact on Brunello Aging
- Whole cluster stems provide natural pH buffering during 2+ years
- Stem tannins polymerize beneficially after 18 months
- Enhanced complexity emerges in year 2 of aging
- Adds "Burgundian" silkiness to Sangiovese's natural austerity
- Critical: excess whole cluster destroys Brunello typicity
Section 4: Ultra-Low Sulfur Protocol for Extended Aging
Scientific Foundation
Brunello's mandatory extended aging presents unique challenges for minimal SO2 use. Research demonstrates wines with <20ppm total SO2 can achieve 10+ year ageability through proper phenolic management and pH control⁸. Sangiovese's naturally high acidity (typical pH 3.2-3.4) provides inherent antimicrobial protection⁹.
Brunello-Specific SO2 Management
Your 10ppm at crush protocol - precise application:
- Preparation: Dissolve SO2 in small amount of must first
- Application timing: During destemming, not after
- Distribution method: Spray solution evenly during crushing
- Temperature requirement: Must below 20°C during addition
- pH verification: Confirm <3.4 before any SO2 addition
- Documentation: Record exact amount, time, temperature
Compensation strategies for 2+ years aging without additional SO2:
- Dissolved oxygen target: <0.2 mg/L (stricter than conventional)
- Temperature control: 12-14°C constant throughout aging
- Barrel topping: Every 10 days first year, biweekly second year
- Complete lees contact for 12 months (natural antioxidants)
- Inert gas (argon preferred) for every movement
- No racking unless absolutely necessary
Brunello bottling without additional SO2:
- Natural cork quality critical - test every lot for TCA
- Vacuum corking essential (<1% oxygen in headspace)
- DIAM cork alternative if TCA risk too high
- Bottle aging at 14-16°C for minimum 4 months
- Accept 2-3% bottle variation as natural expression
Monthly Stability Monitoring
- pH (target 3.2-3.5)
- Volatile acidity (<0.6 g/L)
- Free SO2 (will decline from initial 10ppm)
- Dissolved oxygen (<0.2 mg/L)
- Microbiological stability (plate counts)
- Molecular SO2 (calculate from pH and free SO2)
Section 5: Cover Crop Systems for Montalcino Terroir
Scientific Foundation
Montalcino's Mediterranean climate (600mm annual rainfall, severe summer drought) requires specific cover crop strategies. Research from Chianti demonstrates appropriate cover crops reduce Sangiovese vigor by 25% while improving must quality parameters¹⁰. Galestro soils benefit particularly from nitrogen-fixing species due to naturally low organic matter content (typically <2%)¹¹.
Brunello Vineyard Cover Crop Protocol
Species selection optimized for galestro soils:
- 40% Subterranean clover (Trifolium subterraneum) - self-reseeding, drought tolerant
- 30% Annual fescue (Festuca annua) - low water competition
- 20% Field beans (Vicia faba minor) - 60kg N/ha fixation
- 10% Barley (Hordeum vulgare) - quick organic matter
Management timeline for Montalcino climate:
- October (post-harvest): Seed at 60kg/ha after first rain
- February: Assess growth, no intervention needed
- March: Mow alternate rows only if excessive (>40cm)
- April: Roll/crimp before flowering to create mulch
- May-September: Maintain as dead mulch for water retention
Parcel-specific adjustments:
- Young vines (6yr): 40kg/ha only - minimize competition
- Mature vines (10-30yr): Full 60kg/ha rate
- Steep slopes: Add 20% more barley for erosion control
- Replanting areas: No cover crop years 1-2
Expected Impact on Brunello Quality
- Berry size reduction: 15-20% (concentration effect)
- Must nitrogen: Maintained at optimal 140-180mg/L
- Soil organic matter: 0.5% annual increase
- Water holding capacity: 20% improvement after 3 years
- Natural vigor control eliminating need for hedging
Section 6: Zero-Copper Disease Management for DOCG Compliance
Scientific Foundation
Montalcino's humidity (especially April-June) creates significant disease pressure requiring intervention. Recent studies demonstrate botanical extracts achieve 70% efficacy compared to copper for downy mildew control¹². Combining multiple botanicals with biocontrol agents can achieve commercially acceptable protection while maintaining natural principles¹³.
Disease Management Without Copper or Synthetics
Primary spray program (April-July):
Week 1 rotation - Downy mildew focus:
- Horsetail decoction (Equisetum): 1kg dried/10L water
- Ferment 14 days before use
- Application: 300L/ha (adjust for slope)
- Timing: Dawn application for optimal absorption
- Efficacy: 60-70% vs untreated
Week 2 rotation - Powdery mildew focus:
- Orange oil (d-limonene): 3ml/L
- Plus potassium bicarbonate: 5g/L
- Critical during flowering (May-June)
- Avoid application above 25°C
- Efficacy: 75-80% vs untreated
Week 3 rotation - Biological control:
- Trichoderma harzianum: 10⁸ spores/ha
- Establishes endophytic colonization
- Persists 20-30 days on Sangiovese leaves
- Compatible with all botanical sprays
- Preventive action only
Week 4 rotation - Protective film:
- Propolis extract: 2ml/L
- Plus bentonite clay: 10g/L suspension
- Creates physical barrier
- Reapply after 20mm rain
- Acceptable for all regulations
Emergency Interventions (If Disease Exceeds 5%)
- Chitosan: 2g/L (maximum 3 applications/season)
- Essential oil blend: Oregano (0.5ml/L) + thyme (0.5ml/L)
- Whey: 10% solution for powdery mildew
- Accept 10-15% yield loss rather than compromise principles
- Document losses for DOCG authorities
Realistic Expectations
- Target: 85% of conventional protection level
- Accept: 10-20% yield variation between years
- Monitor: Weekly scouting essential
- Document: Every application for transparency
Section 7: Manual Precision Viticulture for Brunello Quality
Scientific Foundation
Brunello's single-variety requirement makes within-parcel differentiation crucial for complexity. Manual precision viticulture achieves 85% of technology-based results through systematic observation¹⁴. Galestro's variable depth (0.5-2m) creates natural vigor zones ideal for selective harvesting and quality segregation¹⁵.
Brunello Parcel Management Without Technology
Zone identification for each parcel:
June assessment (peak vegetative growth):
- Create 20m x 20m grid with stakes
- Count shoots per meter of cordon
- Measure average internode length
- Assess leaf layers at fruit zone
- Map three distinct zones:
- Low vigor: <10 shoots/meter, short internodes
- Medium vigor: 10-15 shoots/meter, optimal
- High vigor: >15 shoots/meter, excessive growth
Harvest timing by zone (September-October):
-
Low vigor zones: Harvest first
- Higher concentration but lower acidity
- Ideal for Brunello structure
- Pick at 24-25 Brix
-
Medium vigor zones: Optimal quality
- Perfect balance for Brunello
- Pick at 23-24 Brix
- Best complexity potential
-
High vigor zones: Harvest last or declassify
- Often better suited for Rosso
- Risk of green characters
- May need longer hang time
Quality segregation for Brunello vs Rosso:
- Best 60% of production → Brunello
- Next 30% → Rosso di Montalcino
- Remaining 10% → Declassify or bulk
- Never compromise Brunello quality for yield
Data Collection Without Digital Tools
- Hand-drawn maps with consistent grid reference
- Photos from identical positions monthly
- 100-berry samples per zone weekly from veraison
- Detailed harvest journal with:
- Date, zone, yield, Brix, pH, TA
- Weather conditions
- Sensory notes
- Fermentation observations
Section 8: Oak Vessel Protocol for Brunello's Extended Aging
Scientific Foundation
Brunello requires minimum 2 years in oak per DOCG regulations. Research shows that combining French and Slavonian oak creates superior complexity - French oak (Quercus petraea) provides elegant vanilla and spice notes through lactone compounds, while Slavonian oak (Quercus robur) offers neutral maturation with gentle tannin integration¹⁶. DRC's approach of 95-100% new French oak for 16-18 months³² demonstrates that extended new oak contact requires exceptional fruit concentration. For Sangiovese, a more nuanced approach balancing both oak types achieves Burgundian elegance without overwhelming the variety's delicate aromatics.
Brunello-Specific Oak Protocol
Traditional Vessel Selection:
- French oak tonneaux (500L): Larger format than Burgundy's 228L provides gentler integration
- Slavonian oak botti (20-30HL): Traditional for Brunello, provides oxidative evolution without flavor
- Combination approach: Proven by producers like Talenti using 60% French tonneaux, 40% Slavonian⁵⁴
Year 1 (Months 1-12) - Primary Structure Development:
French Oak Component (50% of production):
- 500L tonneaux (not 228L barriques - too aggressive for Sangiovese)
- Toast level: Medium to medium-plus (never heavy)
- Oak age mix:
- 20% new oak (maximum for natural philosophy)
- 30% second-use (1-2 years old)
- 50% third-use or older (3-5 years)
- Purpose: Gentle spice integration, mid-palate texture
Slavonian Oak Component (50% of production):
- 20-30HL traditional botti
- Minimum 5 years old (preferably 10+)
- No flavor extraction, pure oxidative evolution
- Maintains Sangiovese's cherry/violet character
- Traditional thickness: 5-7cm for optimal micro-oxygenation
Year 2 (Months 13-24) - Integration and Refinement:
Racking and Blending Protocol:
- Month 12: First racking and initial blending trials
- Combine French and Slavonian components
- Transfer to:
- 70% neutral Slavonian botti (10+ years old)
- 30% older French tonneaux (5+ years old)
- Purpose: Harmonization without additional oak impact
Creating Burgundian Touch:
- French oak provides lifted aromatics and silky texture
- Slavonian preserves fruit purity and terroir expression
- The combination creates complexity without domination
- Similar to DRC's philosophy but adapted for Sangiovese's lower concentration
Temperature and Humidity Management
Optimal conditions throughout aging:
- Temperature: 14-16°C constant (cooler than typical 18°C)
- Humidity: 75-80% to minimize evaporation
- Natural caves ideal, otherwise climate-controlled
- Monitor "angel's share": Target <3% annual loss
Topping and Maintenance Protocol
Year 1 (Higher attention needed):
- Top every 10 days first 6 months
- Bi-weekly months 7-12
- Use same wine from same vessels for topping
- Never use SO2 in topping wine
Year 2 (Stabilization period):
- Top monthly
- Minimal disturbance
- Natural clarification occurring
- No movement unless essential
Vessel Selection Criteria
French Oak Sourcing (Burgundian approach):
- Forests: Allier, Tronçais, or Vosges (tighter grain)
- Air-dried minimum 24 months (36 preferred)
- Medium toast with slow, gentle fire
- Cooperages used by Burgundy producers preferred
Slavonian Oak Tradition:
- Source: Croatian highlands (traditional for Brunello)
- Minimum 4-year air drying
- Assembled using traditional methods
- Capacity: 20-30HL optimal for small production
Pre-Bottling (Months 24-26) - Assembly:
- Blend components in neutral Slavonian botti
- Natural cold stabilization if needed (12°C for 3 weeks)
- No fining agents ever
- No filtration (achieve <4 NTU naturally)
- Gravity transfer only
- Rest 2 months before bottling
Expected Evolution Timeline
Months 1-6: Primary fruit preserved, gentle oak integration beginning Months 7-12: Tannin polymerization, color stabilization Months 13-18: Oak integration complete, complexity building Months 19-24: Full harmonization, tertiary notes developing Months 24+: Ready for bottling, showing both elegance and structure
Quality Markers for Success
- No dominant oak flavors at any stage
- Preserved cherry/violet Sangiovese character
- Silky tannin texture by month 18
- Natural clarity achieved by month 24
- Color evolution from ruby to garnet edge
- pH stability throughout (3.3-3.5)
Cost-Benefit Analysis
Investment required:
- French tonneaux (500L): €800-1200 each
- Slavonian botti (25HL): €3000-5000 each
- Lifespan: French 8-10 years, Slavonian 20+ years
- Quality premium justifies investment
Section 9: Natural Clarification Timeline for Brunello
Scientific Foundation
Brunello's extended aging provides sufficient time for complete natural clarification. Studies demonstrate 24+ months aging achieves <4 NTU turbidity without any filtration¹⁸. Sangiovese's robust tannin structure naturally precipitates during extended aging, eliminating need for fining agents¹⁹.
Natural Clarification Protocol
Months 1-6 (Full lees contact):
- Weekly bâtonnage first month only
- Monthly bâtonnage months 2-6
- Temperature: 14-16°C constant
- Builds structure and complexity
- Mannoproteins provide natural stability
Months 7-12 (Partial lees):
- First racking only if reduction detected
- Keep fine lees, remove only gross lees
- Natural protein precipitation occurring
- Tartrate crystals beginning to form
- Monitor but don't intervene
Months 13-24 (Oak aging):
- Single racking at month 18 if needed
- Natural cold stabilization happening
- Tannin polymerization continuing
- Color becoming stable
- Clarity improving naturally
Months 24-26 (Pre-bottling):
- Target: <4 NTU turbidity
- If >4 NTU: Wait additional 3 months
- Never fine (no egg whites, bentonite, etc.)
- Never filter (pad, cartridge, or membrane)
- Accept natural sediment in bottle
Quality Assurance Without Intervention
- Visual assessment monthly with candle
- Microscopic examination quarterly for microbes
- Taste for reduction (H₂S, mercaptans) biweekly
