Notes

Was going to be a 100% roast barley. A major issue was going to be the amount of fermentable sugar and enzymes I could get out of it. I have added 1kg pale malt (32%) and 300g dextrose (10%) for fermentable sugars, and 200g rolled oats (6%) for mouth feel/ head retention (probably not enough). This leaves the roast barley content at approximately 52% which is still way more than generally recommended.
