Bad Batches, Infection and other QC issues – a follow up
May 29, 2011

Seth asked me to re-direct you to this new link for the QC issues spreadsheet with updated and enhanced features.
Thanks for the speedy update.
Just tonight I’ve added a new column to denote the date that the beer was added to the list. This is driven by a couple requests from fellow beer consumers.
Since I don’t have the dates for existing beers, the default date is the date I created the Excel sheet. From this point out I’ll include the date the beer is added. This will tell people how old the information is and help them judge if the beer they are buying is a safe purchase.
Again, I thank you for your support and do not hesitate to contact me with suggestions for the list.
