When brewers talk about malt quality, the conversation usually focuses on specs like extract, protein, or color. What often gets overlooked is the starting point of all of it: the barley variety.
In Canada, barley breeding and selection are taken seriously. The Canadian Malting Barley Technical Centre (CMBTC) evaluates and recommends varieties that consistently meet the needs of maltsters and brewers. These varieties are tested for malting performance, extract potential, enzyme levels, and overall brewing quality.
For breweries sourcing malt, understanding these varieties gives better insight into consistency, performance, and why certain malts behave the way they do in the brewhouse.
Why Barley Variety Matters in Brewing
Not all barley performs the same once it is malted.
Different varieties bring differences in:
• Enzyme strength and conversion power
• Protein levels and FAN
• Extract yield
• Modification and friability
• Lautering and filtration performance
These factors directly impact brewhouse efficiency, fermentation, and ultimately beer quality.
This is why most modern malts are not built from a single variety. They are blended to hit specific performance targets.
The Core Canadian Malting Varieties
Across Western Canada, a handful of varieties dominate the malting landscape. Based on the latest CMBTC data, varieties like AAC Synergy, CDC Copeland, AAC Connect, CDC Fraser, and CDC Churchill make up the majority of acres seeded for malting barley.
Each one brings something different to the table.
AAC Synergy
AAC Synergy has become one of the most widely grown malting varieties in Canada.
It is known for:
• Strong extract potential
• Good balance of protein and enzyme levels
• Reliable, consistent performance
This makes it a versatile option for a wide range of beer styles, especially where efficiency and consistency matter.
CDC Copeland
Copeland has been a long-standing benchmark in Canadian malting.
It typically offers:
• Lower protein levels
• Clean malt flavor
• Consistent modification
Because of its lower nitrogen content, it is often used in cleaner, more delicate malt profiles where clarity and smoothness are key.
AAC Connect
AAC Connect is a newer variety that has gained traction quickly.
Key traits include:
• Higher enzyme levels
• Strong FAN contribution
• Good performance in adjunct brewing
This makes it useful in blends where additional enzymatic strength is needed, especially in high gravity or adjunct-heavy brewing.
CDC Fraser
Fraser is valued for its higher protein and enzyme contribution.
In practical terms:
• Boosts FAN and enzymatic power
• Supports strong conversion
• Useful in more demanding mash conditions
It is often used to strengthen a malt blend rather than define its flavor.
CDC Churchill
Churchill is a newer addition with growing adoption.
It contributes:
• Balanced performance across extract and enzymes
• Good agronomics for growers
• Increasing availability in the market
As newer varieties continue to develop, options like Churchill are becoming more common in modern malt blends.
Why Malt Is Blended, Not Single Variety
In theory, single-variety malt sounds appealing. In practice, it is not how consistent malt is produced at scale.
Maltsters blend varieties for two main reasons:
1. To balance performance
Some varieties bring higher enzymes and FAN, while others offer lower protein and cleaner profiles. Blending allows maltsters to hit specific targets for extract, modification, and fermentation performance.
2. To manage protein levels
Protein can vary year to year depending on growing conditions. A variety that typically runs higher protein may still be used in a lower protein malt if the crop comes in lighter that season.
The result is a more stable, predictable malt that performs the same way from batch to batch.
What This Means for Brewers
For breweries, the key takeaway is simple.
You are not just buying malt. You are buying a controlled blend designed to meet a performance spec.
That is why reviewing a certificate of analysis (COA) matters more than focusing on a single barley variety. The COA reflects the final malt, not just the raw barley.
Still, understanding the role of different varieties helps explain:
• Why one batch may lauter faster than another
• Why FAN levels shift slightly over time
• How maltsters maintain consistency across seasons
Canadian Barley as a Brewing Advantage
Western Canadian barley is known for its quality, consistency, and strong malting characteristics. The CMBTC recommended list helps ensure that the varieties used across the industry are proven performers in both malting and brewing.
For breweries, this translates to dependable malt that supports efficient brewing and consistent beer.
At Grist Malt Company, our malts are produced using blends of CMBTC recommended Canadian barley varieties. Each blend is built around lab data and targeted specifications, not guesswork.
If you are looking to better understand how your malt is built or want to dial in performance in your brewhouse, it starts with knowing the barley behind it.
