Introduction • Reports • Why and where? • Next to come - M. Sc Biotechnology & Diploma master brewer

Internship at a macro brewery > 1 mio. hl year • Organization • Production - Uniform production of high quality - Control and analysis’ • Processes - Insight to the V-shape theory and product flow - Considerations with handling of large scale - Filtration Stabilization (PVPP) Alternatives to DE

Internship at a micro brewery 10^3 – 10^4 hl year • The art of brewing - Handling of equipment • Raw materials • Sensory

Goals & Transfer of knowledge • Goals are the foundation for constant development and the ability to transfer knowledge from one scale of production to another… Macro brewery - Economics Micro brewery Passion

Goals & Transfer of knowledge • Goals are the foundation for constant development and the ability to transfer knowledge from one production to another… Macro brewery Economics Micro brewery Passion (hl/Ma. H, recycling, waste disposal) (Taste&appearance, customer contact, local) But of course size and amount of different products makes the difference…

Goals & Transfer of knowledge Macro brewery Micro brewery - Function of a large company - More technical approach through analysis and control - Process flow and lean - Full introduction to all types of processes in brewing - Utilities - The art of brewing - Process handling - Raw materials and compositions - Costumer approach

Cultures, ethics and development Do all these new iniatives take away traditions? Are they blocked by traditions? Or are we even ready for them?

Cultures, ethics and development The world of brewing is old and conservative… But… Times are changing and so is the way of brewing due to various factors and aspects… • Spent grain for bio refining or cattle feed? • Membrane filtration and Reinheitsgebot • Fusarium infected barley vs GMO (USA & EU) • Use of enzymes in the future… - Essential with growing markets and prices on raw materials - Ethics and attitude among consumers - Developing countries • Health effects - Silicon

Take home message When your intern asks; ”Why are you doing this? ” And your answer is; ”Because that’s what we’ve always been doing”. Then please ask yourself; ”But why? ” and ”Could we do it other ways? ”
