alright, final assessment. i have used the DME again in 2 brews out of 3 using the same yeast.
i’ve used the briess DME in probably 8 or so brews total over the past year and a half now as well.
yeast for all 3: OYL006 (WLP007 equivalent sort of)
brew 1 - porter with a sulfate:chloride ratio strongly towards chloride
3lbs DME, 3lbs 2row, 3/4lb pale chocolate, 1/2lb chocolate, 3/4lb crystal 60
carbed with 75g dextrose
brew 2 - bitter
90% maris otter, the rest bits of crystal, amber, acid malt, carafaIII
carbed with 85g dextrose
brew 3 - dry stout
3lbs DME, 2lbs maris otter, 1lb roasted barley, 1/2lb flaked barley
carbed with 75g dextrose
brew 2 is just so obviously different from 1 and 3. head retention is okay, but head is minimal on 1 and 3. head on brew 2 is massive and lasts while only getting a tiny bit more dextrose than the others. brew 2’s taste is just bright and in your face, very hoppy. the water profiles for brew 2 and 3 were similar, brew 1’s was different. im just seeing the DME as a likely factor in not making the best brews.
Options for other brands of DME are almost twice the price, while i was always able to get LME that tasted good from my LHBS for a price just slightly higher than the briess DME.

(probrewer forum link in this thread is dead since it moved or something, but another verification of this)
this thread is someone’s estimates through math, but that would add something like 300ppm of sodium to the brews i mentioned above where i used 3lbs of DME. my tap water is at ~8ppm.
i know lots of people use briess DME, but im done with it despite its cheap price and ease of storage/use.
