Naw. Dont have any useful information for them like batch number. One thing to look out for tho if you open one of those ampules and contents are runny like water rather than viscous its surely contaminated. I only caught on because after 4 contaminated brews in a row and sterilizing everything I stopped using the clarity ferm for the next 6 brews and thought my cleaning had finally exorcised the bugs from my equipment. Then lasdt month I did a 5 gal Saison with 4 liter starter of wyeast 3711 and I decided to throw in the last amp of CF. Well BAM! The putrifaction was back. Thats when the lightbulb went on.
BTW I Saved that batch after 24 hours of putrid fermentation by reboiling the wort and pouring it over a German Lager Yeast Cake. The fermentation threw out tremendous volumes of foul smelling sulfurous gases and got rid of any vomitous flavors.
