Why Choose Biasol Brew Flour?

Bia equals food while Sol is short for solution. BiaSol is our family-made, innovative food solution. For every pint of your favourite craft beer, there’s a mountain of spent grain going to waste. Brewers’ spent grain is mostly barley but also some wheat, rice and corn. Repurposing this valuable ingredient means a better flour for you and less waste from a pint at the pub.


The Taste

Our innovative Brew Flour has a delectably malty and nutty flavour. It also adds an earthy, wholesome colour to your baked goods. 

Zero-Waste Driven

BiaSol products are designed to benefit our community and our environment. By repurposing spent grain as a food source, we’re striving to contribute to a zero-waste world.


Highly nutritious

Each bag of Brew Flour is packed full of fibre and high in protein. The only thing you won’t find in here is alcohol – it’s removed in the creation process.
