Does LME need to be boiled?

Or can I just add it at flame out?

Thanks,

Bob

Do a search for "Late Extract Addition."

You will find the answer there.....

Hi,
I recommend boiling it for a short time (15 minutes) to eliminate any possible chance of contamination. I put an article together on late extracts a few months ago.

Cheers,
Brad

But I thought LME was already sterile.

Possibly, but unless you aren't going to boil at all, why not boil it to make sure it dissolves evenly?

Not boiling at all sounds like a bad idea. Are you not adding any hops?

It "should" be sterile...but sometimes it's not. There have been stories of people opening up a can and having mold and other nasties on the top of their extract. So...there may be junk in there you want to kill before you add it to the fermenter. I'd boil for at least 10min, but the recommended for anything is 15 minutes.

Since summer is here, my brewing days will be limited. I want to make a 10 gal batch, but can only boil 6-1/2. My plan is to do a 6 gal boil at about 1.060. Then add 6 lbs LME at flame out and split it between 2 carboys. Top off each with 2 gal water which should put me at 1.055 - 1.058. I did the math real quick so I may be off a little.

I guess not boiling the LME is just to save some time, so I guess I will.

Thanks
