70 Litre Stainless Boiler head room?

[DC]

Hi all, I am thinking of upgrading my current (original HK Plastics) Hop & Grape 60L boiler for a nice new shiny 70L stock pot from our friends in Germany. I have a quick question regarding head space in a 70L pot? During my last 10 gallon brew day my 60L boiler started with 57.6L of pre boil wort which just about filled my boiler and it almost boiled over (see pic below) hence the possible boiler upgrade. If I bought a 70L stainless steel stock pot and was to boil a pre boil volume of say 57.6L would I have enough room to avoid a possible boil over in a 70L pot? Anyone got any pics of a 70L pot with a 10 gallon boil in it?

Nearly boiled over


I was going to just ask how much room would I have left in a 70L pot if I had a pre boil volume of 57.6L but I just know someone would have posted back 70L – 57.6L is 12.4 which I already know I just need to know if that 12.4L space would be sufficient to avoid a boiler over (height wise in the boiler)

Cheers DC

I'd go bigger, I do 50L batches and in the 70L it was quite tight by the time I'd taken losses into consideration. My 80 is much better suited to the task.

for very little extra cost you could buy a 100Ltr copper and never have any problems

my batch size is normally 65ltrs in my 100ltr copper so not a problem for space

Likewise, brewing 50l or 60l batches and the 100l one works very well for me - worth the extra investment.

Yep, I have a 70l because I was worried about the height of a 100l but they are only about 5cm bigger all around. Someone posted that if you get a 70l then at some point you will wish you got a 100l, in my case that is true!!
