Over 450 species of oak trees exist worldwide, all producing acorns that are technically edible for humans after proper preparation. The crucial, non-negotiable step is leaching, which removes bitter tannins that are toxic in high concentrations.

According to botanists, acorns are indeed classified as nuts, but they belong to a different botanical family, Fagaceae, than many common culinary tree nuts. This distinction is crucial for understanding allergen profiles and safe consumption, especially for individuals with severe tree nut allergies.

In nature, yeast cells are predominantly found on ripe fruits like grapes, which have been instrumental in winemaking and brewing since ancient times. This natural occurrence on sweet, fermentable surfaces provides a starting point to understand where brewers yeast, a domesticated strain of *Saccharomyces cerevisiae*, originally came from.

Most people assume acorns are simply a nut, but botanically, a true nut is a dry fruit with a hard shell covering a single seed that does not open to release it. So, are acorns considered a nut? The answer is a fascinating mix of scientific classification and common culinary perception.

For millennia, humans in various cultures have incorporated acorns into their diet, processing them to remove harmful substances. While this tradition continues in some communities, it raises a critical question for modern foragers: is it safe for a human to eat acorns?.
