Question: Lagering temperature control and what options do I have?
Answer:

There are a few methods homebrewers can use to achieve optimum fermentation temperatures. While a refrigerator equipped with a thermostat control will provide the most precise control, there are other, less expensive ways. Many hombrewers have a basement that is typically a few degrees cooler than normal, and many lagers can be brewed in these conditions. To see if your basement is cool enough, simply place a glass of water on the floor with a thermometer in it. Check the temperature several hours later; if the temp is between 45 and 55 °F, you're ready to start brewing lagers....Click to Read full Answer

Question: How long will my lager fermentation last?
Answer:

Each fermentation will depend somewhat on the yeast strain used and other conditions, but lager fermentations can be done in as soon as 10 days. However, it may take as much as 4 weeks for primary fermentation! Secondary fermetation can take as long as 2 -3 months on some styles of beer. Pitching rate, temperature, and proper oxygenation of your cooled wort all can impact the rate of fermentations....Click to Read full Answer

Question: What does laagering a beer involve?
Answer:

Let’s start by saying that you need to have a controlled temperature throughout the laagering process. Most brewers will use a refrigerator with an outside temperature control unit. The thermostat works in opposite of the refrigerator’s thermostat so that your temperatures do not end up too cold. The maximum temperature of most refrigerators is 40 °F. Before the brewing process has begun it is a good idea to prepare your fermentation environment a few days in advance to allow it a chance to stabilize. If you are intending to ferment your lager at a temperature of 48 °F, dial that temperature in on your thermostat a couple days before you begin to allow your refrigerator a chance to stabilize at this temperature....Click to Read full Answer
