Back on 8/9/21, I made a bulk batch of 1.040 SG starter wort using Briess Pilsner DME purchased 5/26/21. I poured the boiling starter wort into sanitized jars and let them cool/seal. 8 jars in total and all of them sealed fine. I did however notice each jar had what appeared to be break material resting at the bottom. I didn't think much of it. The other day I used the first one to make a starter with some GY021 Kolsch yeast. I decanted the wort off the break material and proceeded to make a starter just fine, but noticed the "break material" was gray and gross. It also smelled like Campbells condensed tomato soup. After a quick search it seems that would indicate DMS, but I couldn't find any evidence this is possible when using DME. Any thoughts? I plan to split the overbuilt starter and give a smell/taste before pitching into my Kolsch, but it seems fine so i'm not too worried yet.
