  • Based on the video, what specific challenges are involved in brewing on a commercial scale?

    • Trial and error is still needed to progress from brewing on the laboratory scale to commercial manufacturing.
    • Beer is technically considered a ‘food substance’ and hence is subject to food safety guidelines.
    • Flavour, taste, odour and appearance all have to be consistent in commercial brews and so frequent human sampling is required.
    • All ingredients used for commercial brewing must have traceable origins.
