PERMANENT HAZE you say? Now I'm throwing out my copper chiller Haha. Do you think a copper coil in the boil for 15min and then cooling for 30min could have negative effects?A little copper can catalyse protein condensation in the kettle, if it is still in the beer after the kettle it accelerates Permanent Haze formation in packaged beer. Generally its strongly recommended to not allow any copper into contact with beer. That said there are probably some very minor requirements for copper in trace amounts as there are for Molybdenum, Phosphorous and Zinc, for mash enzymes, that doesnt translate into chunks of metallic copper being good for beer.[/size][/font]
possibly. but any protein it brings out will likely get coagulated in the boil.... so it may even be a benefit. It has been shown to darken your wort though, which is why no-one uses copper boilers anymore (they just clad the outside in copper to make it look pretty.MHB - any likelihood copper will affect beer pre-boil (eg copper manifold, brass fittings etc) or is it just post-kettle you are referring to?
all things being equal (roughly the same inlet set up, roughly the same outlet set up, same inlet pressure, no limit in the source flow) two identical paths in parallel will always give more flow than the same two paths in series.my 2 coils arrived today, as soon as i got home i made a bodgie join of the two coils in series,
and another bodgie coupling to the garden hose, all consisting of some gaffa tape
well it leaked, and i got squirted a fair bit,
even with these leaks i managed a flow rate of 4 litres a minute through 32 metres of 6mm id coil
now the next question is, will it improve flow rate if i connect the coils in parallel ?
Fluid and electricity are much the same.
for a given quantity (voltage or pressure) the amount that gets through (Current or Flow/volume) is dependant on resistance in the line.
2 x 1 ohm resisters in series will give you 2 ohms
2 x 1 ohm resisters in parallel will give you 0.5 ohms.
So i recon you will get roughly 4 times the flow with them in parallel
let us know
Why am I thinking I need some Gucci gear

i have a question ...
will 3 degree cooling water chill my wort down much quicker than say 22 degree water during the first half of chilling (say 100 down to 50) ? or is the difference only going to be apparent as i approach the cooler temps ?
I have been thinking the same thing, my plan is to go from the tap into a immerision chiller in a esky with ice and then into a counterflow to do the wort chilling. I dont know how effective it will be but i suppose there is only one way to find out!
At 100degC, should make a 24% increase in cooling rate
100-22=78
100-3=97
(97-78)/78=0.2436=24%
At 50degC, should make a 67% increase in cooling rate
50-22=28
50-3=47
(47-28)/28=0.6786=67%
At 30degC, should make a 237% increase in cooling rate
30-22=8
30-3=27
(27-8)/8=2.375=237%
This in not a linear increase, as the wort temp drops the benefit increases. An average of 67% across the 100 to 30degC range.
