Generally speaking,

is a 7 1/2 gallon pot big enough for all grain. I am getting ready to do my first batch. I will be fly sparing and know I'll have to get another kettle to drain the mash in, but was hoping this size will do for boiling. I just don't want to spend a lot more money. This would be for five gallon batches.

You can do it...I used the 30qt that came with my turkey fryer on my first couple batches, and it worked alright...just be REALLY careful about boilovers. The first time I did it, I had a bit of a boilover, but the other two times, I just sprayed it a lot with a spray bottle full of cold water around the hot break and was fine.

I did move up to a 10gal pot after those three batches though...and it's much less of a hassle.

It'll be REALLY close. I'd definitely invest in some foam control if you want to try it.

Like Jason said you can do it, but it is tight. I have a 7-1/2 gallon stainless pot and it is exactly 7-1/2 gallons to the rim with cold water. Water expands when hot so the first time I put 6 gallons of hot wort in it I was like "holy smokes" as it was less than an inch from the rim. You have to be careful of boilover and watch it extra close. I started only putting about 5 to 5-1/2 gallons in for the boil and topping off near the end after that, or at least waiting till after the hot break to take the water level up.

I have now switched to a 9 gallon brew pot and it is much easier to manage the boil in.

It's all I've ever used. With 7.5 gallons of liquid I have about 1/4 inch of room to spare. i just monitor the flame and have very little trouble.

Bigger is certainly better, but I've prioritized that towards the bottom of my budgeting wish list.

Sometimes I boil off a few gallons so start with about 7.. a 7.5 g pot with be a PITA in my opinion. Can you do it? Yes but why not get a 10 gallon you'll be happy you did.

I have been using an eight gallon pot, without issue. Unless your doing a really big beer with a high volume of running's which needs to be boiled down, it shouldn't be an issue.

What are you using for heat? If you have a propane burner I would go bigger. If you are doing it on an electric stove your not going to want to try doing over 7 gallons anyways because it would take forever and you can't really get a rolling boil.

Sure it can be done w/ a little extra effort. Foam control drops, or I have also heard of people using generic gas control drops from the pharmacy, they claim same it is the same thing, can't remember what it is actually ?mycelon?

You can also reserve a gallon of the second runnings, and add it during the boil, or you can just start off up near the rim if ya got the guts for it.

You can aslo just scale the batch back to say 3 or four gallons.

You guys advising all this caution are CRAZY. I use a 30qt from a turkey fryer kit as my primary boil pot and it works like a charm. I do 6.5 gallon boils in it no sweat. Just watch it around the hot break.

I recommend 10+ gallons. I boil my hoppier styles for 90 minutes, so I start with about 7.5 gallons of wort. With my 9-gallon kettle, the boil comes pretty close to the top at the hot break and every hop addition. A few drops of Fermcap keeps it down some, but I still have to pay close attention. I usually keep one hand on the gas regulator to cut the heat if it gets too close for comfort. A bigger pot just gives you more flexibility.
