Beer Analysis

Specialist Services for Brewing Makers

A critical factor in laboratory testing is the experience of the analyst undertaking the work. At Leeder Analytical, whether it’s raw materials like malt or water, or your final products, our staff have extensive industry experience ensuring your requirements are understood and met. Some of the services we offer include:

Sugar Analysis

Analysis of sugars in wort and finished product from individual sugars like: fructose, glucose, sucrose, lactose, maltose to full sugar profiles.

Nitrosamines Analysis

In the brewing industry Nitrosamines can be formed when germinated barley is kilned. Leeder Analytical can analyse food and beverage including malt, wort or beer for Nitrosamine compounds including n-nitrosodimethylamine and other compounds down to ppb levels. Typical compounds we can analyse include: N-Nitrosodimethylamine, N-Nitrosomethylethylamine, N-Nitrosodiethylamine, N-Nitrosopyrrolidine, N-Nitrosomorpholine, N-Nitrosodi-n-propylamine, N-Nitrosopiperidine, N-Nitrosodi-n-butylamine and N-Nitrosodiphenylamine.

Organic Acids

A wide range of acids can be determined from totals to individual acids. Some of these include:
Total Acids (TA), Acetic acid,
Citric Acid, L-Malic Acid,
D-Lactic acid, L-Lactic acid,
Oxalic Acid, Succinic Acid
to full acid profiles.
Malt Analysis
No two batches of malt are alike.
The only sure way to predict their effect on your brew is to be able to review malt analysis data. Leeder Analytical can provide a wide range of malt testing services. These include moisture content, colour, diastic power (DP), total protein, soluble protein, screenings <2.2mm, alpha-amylase, carbohydrate profile, etc.

Microbiological
Micro testing can be used to analyse in-process beer for Pediococcus and Lactobacillus from post-boil to bottling. These organisms present a challenge to brewers since they enter the brewery on raw materials such as grain and can produce lactic acid, altering the taste and aroma of the finished product.
