This has cropped up from time to time and I wanted to know why. Some recipies say to add (for example) 3lbs of dry malt extract and bring to a boil, then as a late addition add 3.75 lbs of liquid malt extract.

Is there some reason that this must be done? I try not to use liquid malt extract (don't quite know why) can I just substatue with dry malt extract and still do the late edition or can I even just skip the late edition and add it right before I boil. Is the late edition to compinsate for lost enzymes or something?

(side question, what's a good "roiling boil" temp? 190 degrees?)

In Cleveland a rolling boil is 212+, cranked to the gills and guns blazing. You want as hard a boil as you get to really agitate that wort, break down the proteins and assimilate those alpha acids.

Late addition on Dry or Liquid reduces the caramelization than can occur with extracts. This minimizes the off flavors associated with that.

Yes you can sub Dry for liquid but you want to compensate for the for the different water content by reducing the Dry by ~20%. The only reason not to do this is the expense.

Less carmelization of the wort and improved hop utilization. If you do a late extract addition, your hop utilization is about the same as if you did a full volume boil, so you save 20-30% on bittering hops.

It's mainly to lighten the color. I've also noticed that heavily caramelized extract changes the flavor of the beer a bit. Just remember to remove the pot from heat when adding LME to avoid scorching.

Wait, you're saying if I am only boiling 2-3 gallons but just add the LME late then I'll get a higher IBU out of the bittering hops? Is that for real? Does adding DME late make a difference in terms of IBUs?

im as new as it gets around here, so im not being a jerk, but if you search late extract addition, a ton of threads will pop up completely explaining everything about the procedure. and dme and lme are the same except 2.75lbs dme = 3.3lbs lme... people seem like like dme more because of less 'twang' and its doesnt have a tendency to carmalize as much....please correct me if i am wrong anybody

Yep, and I say this from experience. In two partial mashes I did a while ago, I tried the late extract addition method but did not change the hop schedule. The beers were more bitter that they should've been. In my las batch i did alter the hop schedule with the help of beersmith and the bitterness of that beer was just right!

If you haven't download beersmith, do it, it takes the late extract addition into account when formulating recipes.

Yes, Sacc speaks the truth. Hop utilization is a function of time, temperature and wort density. If you only do partial boils of 2-3 gallons and then top-up to your final volume in the fermenter, you will see a marked improvement in hop utilization by adding a portion of the extract at the beginning (to get your starting OG around 1.040) and adding the rest at flameout. You will more effectively isomerize alpha acids at this SG compared to the SG from adding all X lbs of malt extract at the very beginning of the boil.

I brewed an American pale ale recently with only 1 oz. of Cascades for bittering with 1 lb. of DME at the beginning of the boil and 6 lbs. of LME with 5 minuted remaining. The bitterness was surprising to say the least and quite a bit more aggressive than I expected with only 1 oz. low alpha hops for bittering.
