![]() Finally, it eliminates the possibility of introducing new oxygen into your brew post packaging. ![]() It also gives you a clear beer to rack to the keg so as not to have additional trub to suck out of (a possibly clog) your posts or lines. It allows brewers who bottle their beer to enjoy the full benefit of gelatin fining, and it removes any further work after packaging. There are four main benefits to adding gelatin to the fermentor. Personally, I prefer adding it to the fermentor during the second day of cold crashing prior to packaging, but others may add to the keg prior to serving. There are different schools of thought in regards to when to add gelatin to your beer. It attaches to proteins and other particulates in suspension and allows them to settle out faster and give way to gravity. Gelatin exhibits a positive charge when mixed with water and then begins attracting negatively charged particles. The way gelatin finings act on particles is actually quite interesting. But, if there is chill haze present or you do not have the patience (like most homebrewers), gelatin will do the job quickly. Cold crashing (bringing your fermentation vessel temp down to around 34 ☏) will speed this process immensely, and if left over time, either in the primary vessel or the serving vessel, will clear on its own. Post fermentation, the yeast will flocculate and drop, as well as hop matter and/or other solids from additions during the fermentation process. Many consider gelatin “liquid time,” as it achieves the clarity that is usually achieved by cold conditioning before or after packaging for lengthy periods of time. Along with other fining agents such as Irish Moss, Whirfloc Tablets, Clarity Ferm etc., gelatin gives a level of clarity beyond the rest. ![]() Many commercial and larger craft breweries may filter their beer and use bright tanks, but on the homebrew level fining with gelatin is far less time consuming and very inexpensive. When seeing the brightness and clarity of other homebrewers’ beer, you may wonder how they achieve such a level in the finished product, and the answer is usually a fining agent known as gelatin. While demonstrating how well-made fresh beer tastes, we also like to focus on the presentation. As homebrewers, we pride ourselves on delivering delicious tasting beer to our friends, family and ourselves. ![]()
