do you choose to stay with PM because of the jump in equipment (outside burner/ big pot)?

The reason you need to care is so that you don't over sparge. The easy rule of thumb is to not use more than 4 quarts of brewing water per pound of grain. That's strike + sparge.

Example. If you mash 4 pounds of grain and strike with 2 gallons (that's 2qts/lb). Given that, you want to limit your sparge to another 2 gallons. Your total preboil will be about 3.5 gallons.

Thanks, Bobby - that's a super helpful tip. Very easy to remember.

I'm assuming you can split up that 4 qts/lb any way you want, right? So, given your example, if I started with 4 lbs of grain and strike with 5 quarts (1.25qts/lb), then I could still be safe with sparging up to 11 quarts?

And if I wanted to add more water after that (to get closer to full boil amount, say), I could do that after removing the grains (I use DB's stovetop PM method)?

Just making sure. Thanks again for the tip.

Yeah, after that sparge amount, any new water should be added directly to the kettle. At that point the PH of the mash could be way the heck off and you don't want to extract tannins and other nasty flavors.

I'm currently an apartment brewer, so I have nowhere to brew outside for now. We're hoping to buy our first house later in the year, so I'll be making the leap sometime after that.
