My 15 year old knows more about brewing than some in my club. His high school teacher was talking about yeast and how it works with grains/sugars. He related it to beer brewing. My son added that rice is a popular grain that is used my major breweries. Teacher disagreed, son challanged him to a Google search and of coarse win. Teacher asked how he knew, to which he responds, my dad brewed at home, and I'm the first assistant!
