No, I'll taste. I just want to get below 4.3 ph so the bad bugs can't reproduce. The last experiment was a little unsettling and I don't want to repeat it. The smell has ruined my Igloo and I'd feel better knowing those bugs are not going to be a problem.
I've reused a mash tun that contained a mash that smelled like vomit without problems. Others have too. I even made a no boil Berliner Weiss using the mash tun. Just clean well and use some sanitizer.
