Lager Experiment: Does Fermentation Temperature Really Matter?
Lager Experiment: Does Fermentation Temperature Really Matter?
Exploring Lager Fermentation: A Brewing Experiment by DrHans Brewery
Welcome to another brewing experiment at DrHans Brewery! Today, we dive into the world of lager fermentation, comparing two lagers fermented at different temperatures 15°C (59°F) and 25°C (77°F) both under the same pressure of 15 psi. It’s an exciting endeavor, especially since it’s my first time trying this side-by-side comparison.
The Angel Yeast Experiment
This experiment is sponsored by Angel Yeast, and I’m using their BF27 Lager yeast, following their recommended fermentation temperatures. The unique aspect of this yeast is its wide temperature range, allowing for varied fermentation profiles. I’ve brewed these beers as part of a split batch, and it’s going to be intriguing to see how the different temperatures impact the final product.
Why Ferment at Different Temperatures?
You might wonder why experiment with different fermentation temperatures. Well, apart from the obvious – brewing curiosity – there’s practicality too. Fermenting at higher temperatures can be faster and doesn’t require specialized cooling equipment. It’s all about pushing the boundaries and exploring what’s possible in home brewing.
Tasting and Comparing
Upon tasting, both lagers have their unique qualities, yet they’re surprisingly similar. The one fermented at 25°C (77°F) seems to have a bit more carbonation, giving it a slightly different mouthfeel. Despite this, they both turned out exceptionally clean, with no off-flavors – a testament to the yeast’s performance.
The Future of Lager Brewing
What’s next, then? Well, if we can achieve such clean lagers at 25°C (77°F) under pressure, I’m tempted to push the limits even further. How hot can we ferment this yeast under pressure while still maintaining a clean profile? It’s an exciting avenue to explore in future experiments.
