As an avid homebrewer, I'm constantly trying ways to improve the quality of my brew. Unless you brew Westvleteren, there is always room for improvement. Tweaks to the recipes, better equipment and better technique are all ways I try to better my beer. And as a maker, I find joy out of building better brew gear.
Whilst reading Brew Like A Monk, I learned of the importance of yeast in beer, in particular how the Belgians don't just chuck in whatever yeast they get their hands on, but rather consider it one of the most important aspects to get right. Careful yeast propagation, concentrations and temperatures all affect beer quite dramatically.
So after been enlightened on the culture of yeast [bad pun, sorry], I decided that my brews were going to get a better yeasting.
