How to Adjust Hop Boiling Times for Adding Extract Later?

[MumbletonLane]

I've seen a lot of suggestions to add some or all of a the Malt Extract well into the boil instead of at the start. This was my third batch so I decided to give it a shot.

My kit came with LME and DME so I did the LME at the beginning, and added the DME about halfway through the boil. In retrospect this should have been predictable, but adding the DME knocked my temperature down enough that it took 15 minutes to get back up to a boil.

The recipe called for adding hops at 60 minutes left, 40 minutes left, 20 minutes left, and 2 minutes left. I added right around 27 minutes left, and when I saw the boil stop and my temp drop, I paused the countdown timer I was using to tell me when to add hops and didn't resume until I got back up to a boil.

I'm not really worried that I ruined my beer or anything but am wondering what is the correct way to stay on recipe if you drop below a boil.

Thanks.

I think you handled it well. My guess, it will probably be really close.

What was the recipe/style? What kind of IBUs were you trying to hit

Good luck.

As far as I am aware you don't really need to adjust hop addition times due to staggered extract additions. Just do the schedule posted in the menu.

One of the reasons often stated for doing late extract additions is to reduce the chance of maillard reactions when using Liquid Malt Extract. Early addition and subsequent boiling of wort with LME can lead to a darkening of the wort, also the possibility of scorching any LME, that has fallen to the bottom of the brew kettle and failed to get suspended into solution, when boil is resumed.

Personally I use 1lb of Dry Malt Extract for my early addition, add another 1lb or so with 10 minutes to go and, more often than not, all of the LME at flame out.

I'd say that what you did by stopping the timer when off-boil then resuming it once a boil was reached again would see your schedule stay on target.

Dude, your fine no worries,
I take it your on the stove top (due to your long restarts)? I've had very good results with the late additions, I brewed an ESB tonight that called for pale 6lbs LME & 1lb DME at 60 min, I only added about 2 lb LME at 60min and added the rest of LME at 5 min and the DME at flameout... done this with many batches and have had good luck! The hopping schedule remains the same time frame wise....

Just curious, I've read that with the late addition method you get more hop utilization and should scale back your bittering hops around 20%.

Did you guys do this and how much did you scale them back?
