I ordered 1 gallon cube inserts for casking: LINK to CUBE INSERT
I plan to store the cube in my temp controlled wine refrigerator.
My brew is an IPA 1.054 OG, 1.008 last checked but not final, still has 9 days to finish dry hoping.
When its done, I originally planned to add 4oz corn sugar for priming. Now that I want to cask 1 gallon of beer and bottle 4 gallons into bottles, what changes do I have to make? Can I add the 4oz corn sugar to the bottle bucket and simply fill the cask or do I have to hold back on some sugar initially and then add the rest later? Thanks for your casking input!
