Notes

• This brew is similar to Brew 30 except for:
  • Less crystal malt.
  • Add minerals

Mistakes

• The sparging wasn't as effective. I should leave the pot to dry out completely before adding more water.
• Another more vigorous boil. I should go back to 30 litres, as I noted last time, but forgot to heed.
