Sazerac 18 rye, one of the five Buffalo Trace Antique Collection releases this year, failed LCBO (Liquor Control Board of Ontario) lab testing. The rumour is the levels of ethyl carbamate were above the LCBO’s limit. This was the probable reason given to me, and others, when calling the helloLCBO number. However, an LCBO spokesperson told me that the results are proprietary and would not confirm the reason behind the failed results.
