Home Brewing is a hobby which permits the production of beer at least as good as any commercial beverage but at a much lower cost. This activity can be as simple or as complex as the home brewer desires. The product will be tailor made to the brewer's taste or that of friends. At its most sophisticated development the commercial process can be almost perfectly replicated. Alternatively a good brew can be made as simply as a cup of tea - although it does take about four weeks. For the very keen brewer the hobby provides insights into chemistry, biology, botany and engineering. A perfect brew from your own production line cannot be bettered.
