Adding half of DME 15 min before end of boil
Have purchased several kits from my local shop. I have noticed that all the recipes call to add half of the DME 15 min prior to the end of the boil. I asked them what's the reason? They claim that it improves the clarity of he beer? Is this true and how can it be?

Not really clarity, but more the color is lighter, and you'll get less of the twang from "cooking" the extract really long.

Yup,it helps get rid of extract twang. But mainly gives lighter color & better flavor. It's mainly LME's that caramelize in the boil after long times. DME's not so much. And you don't have to boil late additions at all. I add them at flame out,since the wort is still boiling hot. Then cover & steep 15 minutes to pasteurize,which happens at 162F. Well below the 180F+ it's still at at flame out. Which should make the color a hair lighter yet.

I started doing this about seven batches ago. The little bit of "extract twang" in a couple of batches I had previously is now gone.
I thought the concept applied more so to LME rather than DME but I do it for both now as just standard procedure.

It has the side benefit of improved hop utilization (some disagreement on that point).

Idk about hop utilization. That's more a function of wort gravity. But this method does apply more to LME,which caramelizes easier than DME. But I also use the late extract method either way.

I like to use DME over LME, but sometimes in a bigger recipe, the price difference will add up, and I'll split it sometimes.

I'll generally go with the idea of adding the DME early, sometimes all of it' if it's under 3 lbs... The the rest of it at flame out. Works pretty well, and no twang.

I don't follow what you mean. Adding half of the extract late gives you lower wort gravity for most of the boil. The brewing software shows increased hop utilization, and my taste buds agree.:confused:

I do partial boils of 2.5-3 gallons,& half a 3lb bag of plain DME. 1.5-2lbs of DME in this case works quite well. The heavier the wort,the less utilization they claim. But this way works well...
