Title: Best size boil kettle for 10 gallon batches
Post by: trendmere on October 01, 2012, 04:00:25 AM
Moving to 10 Gallon batches just wondering what size boil kettle I'll need (ALL GRAIN) ?

The bigger the better. I thought my 16.25 would be plenty. Well,  guess what has two thumbs and still has boil overs? This guy!! So, go big or go home. I would not attempt it with less than 15 gallon, and a good spray bottle.

I use a 20 gallon for my 10 gallon batches and occasionally pull off a 13.

I'm using a 15 gallon, and really wish I had something closer to 20. Go as big as you can reasonably afford.

I just bought a 20 gallon kettle.  It'll have its maiden voyage in a few days.  I figured if I want to make 10 gallons, I'll need to brew 12 to compensate for the sludge in the bottom of the kettle.  If I want 12 gallons, I'll have to sparge off close to 14 gallons.  A 15 gallon kettle just won't cut it.  The 20 gallon kettle was only $30 more at NB.  I figured it was a no-brainer.

So I was wondering something in the 25 gallon range wouldnt be overdoing it?

Nope, not at all.

Blichmann also recommends twice the capacity. With boiloff, your starting volume might be 12 gallons and 3 gallons is usually only 6 inches of headspace. Not much.

I use a 14 gallon kettle and it is pretty close to the top when I finish sparging/lautering. I recommend larger ifd you can, but the 14 gallon works, you just have to feather the flame. That said I always targeted 12 gallons so that I got 5 by the time I was kegging.

I'd go 20G.  Wish I had one myself!  15G will result in boil-overs as I can fully attest to.

If you are careful you can bring the wort to a boil literally an inch from the surface and not have a boil over. You don't have to have the flame turned up full blast all the way through the boil - a gentle boil is all you need.

I never thought it was that difficult to do 10 gal batches in a 15-gal kettle with 60-minute boils.  Add some hops before the boil to avoid a boilover.  That is a good tip from Greg Noonan's Brewing Lager Beer.  15 gal might be small if you are doing 90-minute boils and you want to avoid topping up.

This is where I had my problems.  90 minute boils with BoPils malt where I needed a good rolling boil to get rid of the DMS.  60 minute pale ale/2 row boils are not a major problem, but you still have to be careful.

I use a 20 gallon kettle and what is nice is heating all my liquor at once.  I heat the strike water to mash temp, drain off to my mash tun and leave the rest to heat to sparge temps and then drain to a 10 gallon cooler to keep it at sparge temps.  Saves a little time heating all the liquor at once.

Has that worked for you?  I've FWH dozens, maybe hundreds, of batches and I've never seen it prevent a boilover.

Are you saying it always boils over when you FWH? ;)

Guess it kinda sounded like that, huh?  :)  What I was trying to say is that it doesn't seem to prevent boilovers any more than controlling the flame does.  If I didn't take other steps, I'd have boilovers, even with hops in 7 gal. of wort in a 15 gal. kettle.

I noticed that the wort is less prone to boil over when hops are added before the boil starts. It doesn't prevent boil-overs, but it my experience it makes it easier to control them.

I use a 15gal kettle for 10 gallon batches and have to use a spray bottle to keep the hot break from boiling over more often than not, but it does work. A 20gal kettle would be a better choice, but I'm not planning to upgrade anytime soon.  A little spray bottle action does the trick for me.

Wow. You guys must all cook bacon on high, too. ;) No need to have the flame up so high that you need a 20 gallon klettle for a 10 gallon batch. The spray bottle is a good suggestion, though.

I'm with Keith here, I've got a keggle that I do 10 gallons in all of the time.  I rarely have a boil over, and if I do it is because I am not paying attention.  Fiddle with the burner, use a little fermcap maybe (although not so much lately) and it's really no problem.

+1, I've got a 50 liter kettle and unles I am doing a wheat beer (and I have almost had a boil over with 5 gallon batches of wheat beer, gotta keep your mind focused) I can do a 10 gallon batch without much problem. still have to pay close attention as the hot break happens but with a little stirring or a spritzer bottle and some flame control it's all good.

You can still get boil overs with 10 gallon batches in a 20 gallon pot, even with 10 gallon batches.

I have had success with boiling 18+ gallons in a 20 gallon boilermaker using Fermcap-S.

Same here. Don't turn your back on it until it is under control.

Fermcap rocks!  In the boil and the fermenter!  No boil overs or blowouts.

What was the saying...a watched pot never boils and an unwatched pot always boils over.... Oddly, I have a dial thermometer on my keggle pot, so as it approaches a boil I stay attentive to it, often stirring it into the boil stage and that solved my boil over issues (except on those busy double batch days when I have too many things going on at once)!

I started out with the Blichmann Boilermaker 15 gallon kettle for 5 and 10 gallon batches and got great use out of it.  You just have to be very careful during the hot break.  I now use that as my HLT after upgrading my system to a 3 tier brewstand.  My new boil kettle is a 20 Gallon Blichmann Boilermaker, and all I can say is...IT IS GREAT! No chance of a boilover! So I don't have to be so careful with turning down the flame during the hot break.  Plus, it's only a few dollars more than the 15 gallon kettle.  Blichmann is a bit pricey, but the way I look at it is: I'm going to be doing this for a very long time so I want something that lasts, it has every feature needed like a brewmometer, dip tube, sanitary ball valve, sight glass, lid easily hangs from the handles, can add a false bottom if later in life you want to have a larger heated mash tun,  it's made of a great quality stainless steel, PLUS it looks bad-ass in my brewery.

I just completed my first 10 gallon batch (foreign extra stout) this weekend! I used two converted 15 1/2 gallon SS kegs I got for cheap and a newly acquired 60qt cooler. I actually have a third keg I'm considering using as a mash tun but I'm not sure how to keep my mash temp and not confident that a direct-fired option won't result in some burnt wort. I also used a home-made three tiered rig I put together using those slide-together wire shelves and some angle iron. I used a home-made IC and had my S.O. help me put the BK into an ice bath after flameout. It took me about 1/2 an hour (with an occasional stirring) to get down to 75°. As a side note, I mashed at 1.3qt/lb. with 37lbs of grain and it filled my cooler up to within an inch of the top. And, with 13 gallons of wort, made about 15 minutes of vigilance (and a good spray bottle) at the beginning of the boil a necessity.  :)

Just read the subject line from the OP on this again.  I stick with my opinion that the "Best" size boil kettle for 10g batches is 20G.  You can get by and be very successful with a 15G (as I have) but 20G is optimal IMHO.  No need for fermcap, standing over the pot like a vulture, constantly adjusting heat, not being able to get a good rolling boil, etc....
