Although today any golden, transparent beer is called a ‘blonde,’ there was a time when there was only one: Pilsner Urquell (Plzeňský Prazdroj), the first beer of its kind in history.
A characteristic feature of beer history is that for almost its entire existence, it was produced with Ale yeast, until the early 20th century when brewing with Lager yeast was massively introduced.
Yeasts are more diverse than we think; there are thousands of species and they inhabit almost all natural environments on the planet, being used in food production and/or to produce antioxidant compounds and sunscreens.
