100% Michigan Homestead Grown, 100% Open-Pollinated - Each & Every Seed
Barley is the fourth most important cereal in the United States, mostly for livestock feed and then brewing. I am growing both hulled and hulless varieties. Assuming my dehulling experiments are productive, ultimately, I will focus on varieties that perform the best in my fields. Long term, I'd like to try my hand at malting for home brewed beer.
Wikipedia reports leaf rust, also known as brown rust, is an significant barley fungal disease caused by Puccinia hordei. Most of the US commercial varieties are susceptible. There is a discussion of which genes provide resistance here. I will note in the description observed rust activity in my very non-commercial barley collection. Further, stem and other leaf rusts are discussed here.
Barley flour can be mixed with wheat flour. 10 to 25% is recommended. Here is a vigorous discussion of two row vs six row for brewing. My take-away, for homebrewing, I'll use what grows well.
I grow my barley in Michigan as Spring planted annual. The USDA has a fine growing guide for planting details. I am trialing/searching for Fall planted varieties to spread out the workload and get ahead of the Summer heat!
