Jeg fikk to svar med noen timers mellomrom:
Hi Reinhard,
Thanks for your email, this is not normal to have yeast as dark as chocolate. I would like to follow up with our QC team about this. Could you please send me the following info:
- Lot number
- Photo of yeast and package
- Details of the retailer where you purchased the yeast (Name, city, country)
If you still have any unopened sachets, please save them for now, I may request that they be sent to our lab for testing.
Cheers,
Eric Abbott, M.Sc.

Hi Reinhard,
Thanks for your email, I appreciate your concern about yeast having a different color. We do occasionally have issues with a darker lot of yeast, which has been attributed to variations in our raw materials. The color difference does not indicate any difference in quality or performance (i.e. its not burned and low viability). Rest assured that any dry yeast that we sell has passed our stringent QC process, which includes testing for viability, bacteria and wild yeast, stability, fermentation performance and flavor analysis of the resulting beer. You can go ahead and continue to use the yeast, it should ferment normally.
Cheers,
Eric Abbott, M.Sc.

Der er jo litt forskjell på disse svarene, men jeg antar Abbott diskuterte problemet med QC teamet og konklusjonen ble at det ikke var noe problem.
Jeg kan jo også si at den starteren jeg satte oppførte seg helt normalt og det var full aktivitet etter 2 timer.
