Quiz: Which crop is the 4th largest grain crop in the world? Hint: it is the crop that is the base of one of the oldest beverages mankind has produced and which is still our most popular alcoholic beverage. This crop was responsible for the domestication of mankind. Its seeds aren’t much good for bread making but do well in many other products. Overall, the crop is responsible for millions of jobs across Europe. However, this species is suffering from climate change, yielding eight percent less in the hot & dry summer of 2018. Left unchecked, beer might soon be out of reach for millions on this planet. Lucky for us, plant breeding, science and innovation, saved the day and saved this crop.
