I usually brew up a 1.5 gal boil and place 4 - 1 gal containers of water in the freezer for 4-5 hours prior to brewing.
I pour my wort through a nylon strainer on my primary to get out all the hops, etc. Then I sparge (rinse) the hops with the cold freezer water until it's about 5.25 gals.
The temp is usually down below 70F and ready to pitch the yeast.
Don't forget to take a temp and gravity reading prior to pitching the yeast.
