I think its high time i get a wort chiller . Couple of questions i extract brew at present in a smallish stockpot so if i male my own chiller i can get the tight size but is there a standard of how much of the coil is in the wort etc ?.For when i move to bigger boiler etc. And how do you get the other end of the pip up through he chiller without neding or kinking it. I resisiting the urge to buy one as the cost to make one seems to be so much better than ready made ones. And does size and length of the pipe matter ?
