A brewery is a facility where beer is produced through the fermentation of ingredients like water, malted grains, hops, and yeast. The brewing process involves several steps, including mashing, boiling, fermenting, and conditioning. Breweries can vary in size, from small craft operations to large commercial enterprises. Many breweries also offer tours and tastings, allowing visitors to learn about the brewing process and sample different types of beer. Some breweries may focus on specific styles, such as lager, ale, or stout, while others experiment with unique flavors and ingredients to create innovative brews.
