I've been wanting to brew a winter ale with Marris Otter. I've never actually brewed with this malt, so I don't know much about it. I typically would use a 2-row, but thought I'd change it up. I was reading the wiki page on Marris Otter and it states, "its yield has been surpassed hugely by more modern varieties, so it has to be grown on contract for the maltster each year by selected farmers."
According to the malt chart and assuming I'm reading the information as its meant to be read, 2-row (as I understand to be the most popular base malt) has a potential yield of 77.9%, while Marris Otter has a potential yield of 82.2%.
Am I misunderstanding the information? It sounds like Marris Otter has a higher yield potential than the standard 2-row.
