I can offer a bit of background. My late father in law worked for a government/EU quango called Home grown cereals authority. As a chemist he joined them in 1960s the idea behind the organization was at the time we imported a large amount of grains for brewing, distilling, baking and animal feed so the quango was set up to improve our efficiency and he was working mainly on long term storage. MO had been first grown before he started but he did spend a lot of his early time at their lab. helping with further research and he told me it had been developed just for brewing and longer storage life and succeeded beyond expectations and was far better than any other brewing malt available at the time. I recall him telling me a several years later, as a home brewer I was always asking questions, other strains were being improved and or developed also as he was involved in improving communications between the growers, storage, millers and customer to get consistency in the final product the gap was narrowing between MO and other varieties. Towards the end of his career he did say to me the only strain he felt was in anyway better and justified a higher price was golden promise, he felt the Rolls Royce of malt. As a footnote when he retired we were self sufficient in grain and he received an MBE for his work.
