I keep grain at my office when too much is on hand to keep at home. Temperature controlled etc. I cut open a bag of Weyermann Vienna today to weigh out for Saturday and gave a small handful to a few of my partners and told them to chew on it. That they'd understand where some of a beers taste comes from. They all actually liked it. Tasting that cereal sweetness and how it has that hot cereal component.
Next time any one of them has a beer I guarantee they'll correlate that taste and flavor. That's all. I just appreciated the look of enjoyment on their faces.
