  • Pat explains the difference between two row and six row barley and why he recently shifted his study to two row varieties.
  • We talk about how he is working to breed cold tolerance and disease resistance into new barley varieties.
  • He also explains why per-acre yield and drought resistance is very important for barley.
  • We discuss some of the methods he uses to analyze and breed new barley strains.
  • He explains the impact his work has on harvesting, drying and malting barley and how integral the maltster is to barley development.

  • Pat shares his thoughts on the implications of new barley varieties for brewers and home brewers.

Great show, I hope you don’t get a nasty backlash from the anti-GMO crowd. Genetic engineering is one of the reasons we all have food on our tables, and there’s no evidence that GMO crops are detrimental human health. Cheers!
