When the weather’s hot and the days are short, you might consider making a beer in a container.
But what if you want to keep the brews cold for long periods?
“I have heard of people who have built up a system of wooden containers to store their beer in for up to two months, sometimes years,” said John Egan, a brewing consultant who helped build the system, and is the founder of the Egan Brewing Company.
Egan’s system uses a process called a keg-in-container fermentation system, or KIC, to brew beer.
In a typical batch of a typical beer, a kiln heats a liquid and then condenses the mixture into a kegg that can be poured into a vessel.
This is a process that can take months to complete.
This process creates a brewable batch of beer, and it also reduces the carbon footprint of brewing.
This has the benefit of allowing beer to be stored in a way that’s good for the environment and good for our health, according to Egan.
The process is relatively simple, and can be made in a matter of hours.
