What is graining out in the brewing process? Graining out is a crucial step in the brewing process that involves separating the spent grains from the liquid wort after mashing. During mashing, the grains are soaked in hot water to extract sugars and other fermentable compounds. Once this process is complete, the spent grains need … Read more
What is a Mash Tun? A mash tun is a vessel used in the brewing process to convert the starches in malted grains into sugars through a process called mashing. This vessel is typically made of stainless steel or copper and is equipped with a false bottom or a perforated plate to separate the liquid … Read more
I. What is a Stuck Mash? A stuck mash is a common issue that can occur during the brewing process, specifically during the mashing stage. The mashing process involves mixing crushed grains with hot water to convert starches into fermentable sugars. A stuck mash occurs when the grain bed becomes compacted, preventing the wort from … Read more
I. What are Beta Acids? Beta acids are a class of bitter compounds found in hops, which are essential ingredients in the brewing of beer. Along with alpha acids, beta acids contribute to the overall bitterness, flavor, and aroma of beer. Beta acids are less soluble than alpha acids and are not isomerized during the … Read more
I. What is a hop back in brewing? A hop back, also known as a hopback or hop filter, is a vessel used in the brewing process to infuse beer with hop aroma and flavor. It is typically a small, cylindrical vessel that is connected to the brewing system after the wort has been boiled … Read more
