There is a number of factors that weigh on the amount of time it takes to brew beer. If you have your own brewery in the garage and do everything yourself you can expect the process to last anywhere from a couple of weeks to two months. Actually preparing the ingredients, boiling the wort and transferring it to the fermenter doesn’t take more than a few hours. But once in the fermenter, the process becomes one of waiting. Modern home brewing kits have streamlined the process somewhat but you’ll still need to wait at least a week for your batch to ferment properly.\r
