At Belgomalt, we believe that brewing excellence starts long before the mash tun. It starts with understanding your raw materials - and that means knowing how to read your Certificate of Analysis (COA).

With the launch of the new Belgomalt website, we're introducing an interactive COA tool that makes this easier than ever. Inside each product page, customers will find a live, interactive certificate that walks through every parameter of the malt - what it means, what the acceptable range is, and how it directly affects your brewing process.

What Is a Certificate of Analysis?

A Certificate of Analysis is the technical fingerprint of a malt batch. Barley is a living product - no two harvests are identical, and no two production lots are the same. The COA captures this uniqueness through a series of analytical parameters that describe the malt's physical, chemical, and enzymatic profile.

For a brewer, the COA is not just paperwork. It's a roadmap.

Parameters like Extract, Diastatic Power, Kolbach Index, Friability, Viscosity, and FAN in wort are the variables that determine how your mash behaves, how your yeast performs, and ultimately, how consistent and high-quality your final beer will be. Knowing how to interpret these numbers allows you to adapt your recipe and process to the actual characteristics of each batch — not just a generic average.

An Interactive Experience, Built for Brewers

The new interactive COA page at belgomalt.be/coa allows you to hover over each parameter and get an instant, plain-language explanation of what it measures, why it matters, and how it impacts your brew.

For example:

• Humidity — higher moisture reduces extract yield and shelf life.
• Kolbach Index — a key indicator of malt modification; a well-modified malt supports better head retention and foam stability.
• Betaglucan — directly impacts lautering filterability.
• Alpha Amylase — a core enzyme for starch breakdown; low values can lead to viscous wort and reduced extract yield.

With the launch of the new Belgomalt website, customers can now access this interactive certificate directly within each product listing — making it simple to understand the full analytical profile of every malt before it reaches your brewery.

Why It Matters

Great beer comes from great ingredients, handled with knowledge. The COA is the bridge between the maltster's precision and the brewer's craft. By making it interactive and accessible within the product experience, we're shortening that bridge — and putting more control in the hands of the brewer.

Whether you're dialing in a Pilsner, experimenting with a specialty grain, or troubleshooting a filtration issue, your COA is your best starting point.
