And here is the quote
Parker and Craig Beam insist on using at least 10%…Parker’s been doing this for 52 years, so I’ll put my money on him. The only “big” distiller that I know that’s NOT using at least 10% is MGP Ingredients/LDI in Lawrenceburg, IN. They use 5% in a couple recipes…and am told that they need to add commercial enzymes to make up for it to get the proper conversion…I’m not a distiller, but I’m lucky to have access to distillers that have been around distilling a good long time.
So it seems you need minimum 10% malt barley for starch conversion unless your going to use seperate enzymes. :handgestures-thumbupleft:
