Frassinetto wheat starter - so stinky

Hi everyone - I searched through the "stinky starters" posts, but couldn't find a Frassinetto-specific problem. I recently ended up with a few pounds of this flour, and thought I'd make a new starter with it. The first try yielded a fermented thing that was increasingly pungent and gag-inducing.

I've seen descriptions like "socks, vomit, cheese * 1,000,000", but it isn't any of these. I have a healthy starter about a year old, and that one is yeasty and warm, sometimes a little astringent if I've starved it, so I have some idea of what a healthy starter smells like. The Frassinetto one smells like...rotting vegetation and maybe cat turds? There's a slight sharpness, but overall, it's a stink that stays in my nostrils. 

I thought perhaps my container or mixing utensils or water had something that caused this, so I sanitized another container, utensil, and filtered water to try again. It's day 4 now, and the smell isn't as strong, but it is starting down that route again. I've already decided to throw away the first Frassinetto try, because I can't keep from gagging when I open the jar. It's in the freezer right now so I could scrape it all out in one go to toss it that way.

I guess I'm wondering if anyone has ever tried using this wheat for a starter, and if so, is this just the stench quality of this wheat?? I'm willing to stick with it and keep feeding it white AP flour if the battle could be won. I started to do that with Frassinetto-1, but it stopped bubbling and just sat there a little paler and sludgier after AP flour feedings, so I thought the baddies might have just taken over.

Any insight would be appreciated! Sorry for the long first post! I just want to raise them right!
