Do you have problems with chill haze or clarity in general? My first thoughts are that a late addition wouldn't allow time for proteins to settle out.
Yooper,
IYO was my 2:4 ratio ok?
In my experience, I don't always get a hot break from DME anyway so I never saw any differences in clarity.
I get a lil hot break every time with DME. Just for the usual 3 minutes or so. And that's 1.5lb of DME in 2.5G of boiling water. Then hop additions,remaining 1.5lb DME at the end with all the lme while the water is still boiling hot. Cover & let steep for 15 mins while I do sanitizing on the fermenter.
It's when you chill extract wort down as quick as possible that you get proteins flocculating & settling out. Pour through fine mesh strainer into FV to remove them & other particulate matter.
I use 1 can of LME (max of 3.75lbs) & one 3lb bag of plain DME. Hops type/amounts/schedules very by style. I use half the bag (1.5lb) in the 2.5G partial boil. Do my hop additions,then add the remaining DME & all the LME at flame out. Mix well & let steep covered for 15 minutes.So are you using 3 lbs of DME with every recipe and LME for the rest? If so, hows that working out for you? I'm just curious, seem to be a million different DME vs LME opinions, havent really settled on a solid conclusion of my own yet.
