Nice one. What size is your boiler mate. Love that you can see the wort from the outside. Like a sight glass without the hassle. Theres some calculators for adding back water after to reach your abv but i cant remember if they suggest pre or post fermentation. Itll be a great pint!
30 litre. Actualy about 27 lites.


. swill it out after use then soap and water the boiling will kill everything, try you finger in there for the 90 min boiling time
