I have the same opinion of LME. It could have been other factors in my process but I never made an extract brew that I considered of acceptable quality. Call it twang I don’t know but it was like a combination of staleness and maybe when you use too much crystal.
Had much better luck with AG and recommend it highly. You can always have issues but I’ve found the quality to be far superior to extract. Or....in my case I just do what works for me.
