Only 9 of 152 Scottish Distilleries Still Practice Traditional Floor Malting: The Industry's Supply Chain Reality
The Scottish Whisky Industry's Supply Chain Reality
Behind the marketing promises of "traditional methods" lies a shocking reality: of Scotland's 152 active whisky distilleries, only 9 still practice floor malting. Even among these few, most produce just 15-30% of their malt requirements on-site.
The remaining 94% rely entirely on commercial suppliers, with just two companies—Simpsons Malt and Crisp Malt—controlling approximately 65-70% of Scotland's whisky malt supply.
This isn't just about one distillery—it reveals how the entire Scottish whisky industry operates.

Having observed the extensive restoration work at Glen Garioch's Old Meldrum site, I've witnessed firsthand the complex logistics behind their malting operations.
What Beam Suntory Actually Achieved
In 2020, owners Beam Suntory invested £6 million to restore Glen Garioch's traditional production methods, including:
- Floor maltings restoration - Operational since early 2022
- Direct-fired wash still - Returning to pre-1997 heating methods
- Four additional maltings operators - Hired specifically for floor malting operations
- Training program - Staff sent to Laphroaig and Bowmore to learn traditional techniques
The Surprising Production Reality
Despite this massive investment, Glen Garioch's floor maltings can only supply 25% of their total malt requirements. The remaining 75% must come from commercial suppliers.
Why this matters for whisky buyers: Every Glen Garioch bottle contains malt from multiple sources, creating a complex flavor profile that goes far beyond what the distillery can control on-site.
The Commercial Malt Suppliers Dominating Scottish Whisky Production
From an engineering perspective, the supply chain reveals a shocking concentration of power: just two companies control the majority of Scotland's malt supply.
How Two Malt Suppliers Control 65-70% of Scottish Whisky Production

Simpsons Malt (Berwick-upon-Tweed):
- Produces 200,000 tonnes annually - enough for 40+ major distilleries
- Sole supplier to The Macallan for 25+ years (every bottle!)
- Supplies Chivas Brothers - including The Glenlivet, Royal Salute, Ballantine's
- Estimated market share: 35-40% of all Scottish whisky malt
- Also supplies: Glen Garioch, Highland Park, Craigellachie, others
Crisp Malt (Alloa & Portgordon):
- Operating in Scotland for 40+ years
- Portgordon facility: 162,000 tonnes capacity (expanded from 42,000 in 2024)
- Alloa facility: Additional production since 2003
- Combined Scottish capacity: ~200,000+ tonnes annually
- Market position: "There aren't many big producers we don't supply" (Production Manager)
- Specializes in plain, peated, and high diastatic malts
Combined market control: With Simpsons at 260,000 tonnes and Crisp at 200,000+ tonnes, these two suppliers control approximately 65-70% of Scotland's whisky malt production.

The Transportation Engineering Challenge
Moving malt from these suppliers to Old Meldrum requires sophisticated logistics:
- Bulk delivery trucks - 25-tonne capacity, specialized pneumatic systems
- Storage silos - Climate-controlled for moisture management
- Quality control protocols - Testing every delivery for consistency
- Inventory management - Balancing floor malt with commercial supplies
The Engineering Reality of Floor Malting vs Commercial
Floor Malting Limitations at Glen Garioch
Production Capacity:
- Floor maltings: ~750 tonnes per year (25% of needs)
- Total requirement: ~3,000 tonnes annually
- Shortfall: 2,250 tonnes from external suppliers
Labor Intensivity:
- Four full-time maltings operators
- 96-hour malting cycle per batch
- Hand-turning every 8-12 hours
- Quality monitoring throughout process
Commercial Malting Advantages
Efficiency Metrics:
- Simpsons Malt: 200,000 tonnes vs Glen Garioch's 750 tonnes
- Automated systems: 24/7 operation with minimal staffing
- Consistent quality: Computer-controlled temperature and humidity
- Cost effectiveness: 60-70% lower per tonne than floor malting
What This Means for Glen Garioch's Flavor Profile
The Blending Reality
Every Glen Garioch expression contains:
25% Floor Malt Characteristics:
- Enhanced body and mouthfeel
- Traditional peaty undertones (when used)
- Hand-crafted texture variations
- Historical terroir connection
75% Commercial Malt Impact:

- Year-round availability
Quality Control Challenges
Master blenders must balance:
- Batch variations from floor malt seasonal changes
- Supply chain consistency from multiple commercial sources
- Inventory management of different malt types
- Flavor standardization across production runs
The Industry-Wide Reality: Only 9 Distilleries Practice Floor Malting
The numbers tell the complete story of Scottish whisky's malt dependency:
The Current Statistics (2024):
- 152 active Scottish distilleries (Scotch Whisky Association)
- Only 9 have operational floor maltings (5.9%)
- 143 distilleries (94.1%) buy 100% of their malt externally
- Of the 9 with floor maltings, most produce only 15-30% of requirements
- Only 1 distillery (Springbank) achieves 100% self-sufficiency
Major Scottish Whisky Brands That Rely 100% on Commercial Malt Suppliers:
100% External Malt Dependency:
- Glenfiddich (despite massive scale)
- Johnnie Walker distilleries
- Dewars portfolio distilleries
- Most Diageo distilleries
- Most Pernod Ricard distilleries
- Nearly every Islay distillery except Kilchoman/Bowmore/Laphroaig
Complete List of Floor Malting Distilleries:

- Springbank (Campbeltown): 100% own malt - the only fully self-sufficient distillery
- Balvenie (Speyside): ~15% own malt, 85% external
- Highland Park (Orkney): ~20% own malt, 80% external
- Kilchoman (Islay): ~20% own malt, 80% external
- Glen Garioch (Highlands): 25% own malt, 75% external
- Laphroaig (Islay): Partial floor malting for peated character
- Bowmore (Islay): ~30% own malt, 70% external
- BenRiach (Speyside): Floor maltings revived in 2012
- Abhainn Dearg (Lewis): Small-scale floor malting operations
Why 143 of 152 Distilleries Abandoned Self-Sufficiency
The economics are compelling - explaining why even premium distilleries surrendered control of their core ingredient:
Space Requirements:
- Floor maltings: 1,000m² for 50 tonnes per week
- Commercial maltings: Same space produces 500 tonnes per week
- Real estate cost: Floor malting requires 10x more space per tonne
Labor Economics:
- Floor malting: 4 operators for 750 tonnes/year (Glen Garioch scale)
- Commercial: 4 operators for 50,000+ tonnes/year (Simpsons scale)
- Cost per tonne: 60-70% higher for floor malting
- Scale advantage: Commercial suppliers achieve 67:1 efficiency ratio
The Surrender Timeline:
- 1960s-1970s: Most distilleries close floor maltings for "efficiency"
- 1980s-1990s: Remaining holdouts convert to commercial suppliers
- 2000s: Only 6-7 distilleries maintain any floor malting
- 2020s: Industry realizes they've lost control of their core ingredient

How This Impacts Single Malt Scotch Quality and Authenticity
This isn't just about Glen Garioch - it fundamentally changes how you should view Scottish whisky:
Understanding "Traditional Methods" Claims in Scotch Whisky Marketing
When distilleries say "traditional methods":
- 94% mean "we buy industrial malt like everyone else"
- Only 6% actually have any floor malting capability
- Even those typically mean 15-30% traditional, 70-85% industrial
Premium Scotch Whisky Brands and Their Actual Malt Sources
Your Favorite Whiskies' True Malt Sources:
Macallan 18 ($400+): 100% Simpsons commercial malt (25+ year contract) Glenfiddich 21 ($200+): 100% commercial malt despite "traditional" marketing Highland Park 18 ($180+): ~20% own floor malt, 80% commercial Glen Garioch 12 ($55): 25% floor malt, 75% commercial (better ratio than many premiums!)
The Value Revelation: Glen Garioch's 25% floor malt content actually exceeds many whiskies costing 2-3x more.
How to Taste the Difference
Floor Malt Indicators:
- Richer mouthfeel - Hand-malting creates texture variations
- Seasonal character - Batch differences throughout the year
- Traditional earthiness - Connection to local terroir
- Complexity layers - Non-uniform malting creates depth
The Future of Glen Garioch's Malting Strategy
Expansion Possibilities
Given the £6 million investment success, future developments might include:
Production Scaling:
- Additional floor malting capacity
- Target: 40-50% self-sufficiency by 2027
- Enhanced visitor experience integration
Supply Chain Optimization:
- Direct contracts with local farmers
- Reduced transportation costs
- Regional barley variety experiments
The Bottom Line: Every Whisky is a Supply Chain Story
The next time you hold any bottle of Scottish whisky, remember what you're really holding:
94.1% of bottles: 100% commercial malt from 2-3 major suppliers (Simpsons, Crisp, others) 5.3% of bottles: Mixed traditional/commercial malt (partial floor malting distilleries) 0.6% of bottles: 100% traditional floor malt (Springbank only)
This isn't a secret unique to any one distillery—it's the foundation of modern Scottish whisky production. Even your most expensive single malts likely contain the same commercial malt as budget blends.
Glen Garioch's honesty about their 25% floor malting actually makes them more transparent than distilleries charging triple the price while hiding their 100% commercial malt dependency.
The whisky industry built its reputation on tradition, then quietly outsourced that tradition to industrial suppliers. Distilleries like Glen Garioch represent the few attempting to restore some traditional production methods to Scottish whisky.
