Doing my 3rd brew this coming weekend, and plan on doing a late extract this time around, but had a few questions.

I'll be brewing AHS Bavarian hefe kit, which has 6# DME. I was thinking I'll add the lme at 60, and the DME at flame out. Any foreseeable problems with this?

I have read that doing late extract can increase the bitterness of the beer. Is this accurate? How can I adjust the kit to account for the extra bitterness? Or should I just follow the hop schedule in the kit?

And lastly, It will be my first time using an immersion worth chiller. How can I keep lme and DME from gunking up the chiller lines and making a sticky mess? It seems to dissolve pretty quickly when I do normal addition, so I'm not even really sure this will be a problem. I suppose I can pour more slowly than usual and only in the center, giving me a bit of room to stir.

The idea behind the late extract addition is to improve color and minimize the maillard reaction which some will claim creates a "twang" in the taste or additional carmelization of the malts.

Ideally you use 25-50% of the extract at the beginning and the balance at the end. In a full boil setting you will achieve better hop utilization but IMO, there is no need to adjust the hop schedule.

How big of a boil are u planning. The late extract additions deal wiht keeping the color lighter. Longer boils, especially in partial boils, say 2-3 gallons will lead to darker colored beer. Ive read on here of people pitching all their extract within the last 15-20 minutes just to sterilize it and they didn't say anything about affecting the taste.

It will be a 60 minute 6.5 gallon boil (5 gallon batch).

If you were doing a partial boil it would probably balance out (hop wise.) In the full boil the hop utilization will be higher. I use beer Smith to figure it for my wort.

Looking at Beersmith (which is a super useful program, need to buy a key), it looks like if I do 3# at the start and 3# after flame-out, I'll be alright. Estimated IBU will be 12.8, which is just fine for the style, and it really helps the estimated color as well.

I figure to keep the cooler clean, my plan is to boil the cooler the last 15, then pull it with some tongs and just hold it out above the wort while I stir in the DME. The few seconds it'll be exposed to the air probably won't hurt anything.

Maybe it's just me, but I always do the DME first, 60 minute addition, and then add the LME in the last ten minutes, turn down the heat and stir well of course.

Yeah,I use the DME in the boil,since it doesn't darken as quickly as LME. I do partial boils of 3.5 gallons in a 5 gallon BK/MT,even with PM BIAB. Just use 3lbs of the DME in your boil for hop additions,adding all remaining extracts at flame out. And partial boils,even for a full hour,will not darken the beer any more than a full boil would. The late extract additions take care of that whether full boil or partial.

I do the exact same thing.
