Gee that never occurred to me, No my last brew was a Oatmeal Stout. I have read that 2 row is a better base malt so I thought maybe someone who has excess might want to try using some 6 row that might better suit another style to brew.
naaaa.... the biggest difference between 2 row and 6 row is ... 6 row has a higher diastatic power (can convert more specialty grains than 2 row) and has more husk material.. which isn't a bad thing as it can help keep the grain bed from sticking. other than that it's a base grain just like 2 row.
