![]() ![]() Half of 40 SG (10° P) is 20 SG (5° P), which means you can raise the temperature when you measure a specific gravity of 1.030 (7.5° P). If the wort has an original specific gravity (SG) of 1.050 (12.5° Plato) and you expect terminal gravity to be around 1.010 SG (2.5° P), then your lager yeast needs to chew through 40 specific gravity points (10° P) to get from point A to point B. Take regular gravity readings, and boost the temperature by 5° F (2.8° C) when your beer is about halfway to completion. Pitching cold can mean longer fermentation, but there’s a convenient trick to speed things along. Use an appropriately sized pitch and go straight into the cold temperature your yeast strain prefers. If you pitch enough yeast, there’s no reason to pitch warm. But this technique is almost guaranteed to create unwanted esters, which are frowned upon in a great lager. It’s common practice in homebrewing to pitch yeast into room temperature lager wort and then cool the fermentation to 45–55☏ (7–13☌). If making a huge starter doesn’t sound appealing to you, consider using one of the excellent dry strains available, like Saflager W-34/70 or S-189. Aim to pitch about twice as much yeast for a lager as you would for an ale of the same original gravity. Like people, yeasts slow down when they get cold, which means you need more cells to accomplish the task at hand. Lagers ferment much colder than ales, typically in the neighborhood of 45–55☏ (7–13☌). Here are 5 tips that will improve your homebrewed lager, whether you’re a seasoned veteran or a first-timer. Lager is not synonymous with mass-produced yellow fizz water (though that is one of many lager styles), and many who initially stayed away from these fun styles are starting to rediscover their allure.īrewing a great lager does require that the brewer pay a little extra attention to technique, but it needn’t be terribly complicated. ![]() Homebrewers and commercial craft brewers who had initially focused on ale have rediscovered the joys of cold fermentation and the diverse array of lager beer styles. In case you haven’t been paying attention, lager is back.
