Wasn't that a party

It happens because somehow a batch makes it to the bottling phase without dilution. The notion that this is a lab error is preposterous, how does a lab error explain a problem only with this brand and only in this bottle size and only in these specific lots, but which shows everything else tested coming out ok? And there's no way but that this testing was repeated multiple times before issuing a recall notice.

It's all a conspiracy! If I'm not personally privy to every single piece of information someone is hiding something!

Speaking of linearity ... Back in the early 90s I got a job working in a forensic chemistry lab. I was the only chemist there. They already had established methods in place and (supposedly) validated to quantitate substance cocaine, PCP et al. Part of the process for testing substance cocaine was to do two injections on GC for each sample. And to report the result they had to agree within 10%. I was testing a sample of unusually pure cocaine HCl and could not get two injections within the right range. I changed the septum, changed syringes, flushed the column, re-packed the column, checked gas flows, checked the detector (NPD rubidium bead). Nothing worked. Finally I said "I wonder if the instrument response is linear at the concentrations were injecting and ran a series of solutions covering many orders of magnitude and low and behold the nice linear response curved off right below samples which were 100 % pure. I changed the method by adding a dilution step and life was good. I then checked the test for PCP and found it had the same problem and made the same correction. They should have caught this problem before but nearly all street cocaine was cut so they got away with it.

Quantitating ethanol is easy and there are a lot of methods. We used GC-FID which was calibrated by oxidative titration.

Recalls have been issued by liquor boards in at least five provinces. All of them must have made lab errors.

I'll pay the difference and continue to use Everclear for my special cleaning. Isopropanol and methanol and ethanol are chemically different. Each has their own and different properties.

I did make my own automobile fuel additive when the purchasing department once bought an entire skid-load of 'denatured ethanol' that was cheaper than what I ordered. Turned out to be denatured with 5% gasoline. Useless for what we wanted in a biochemistry research lab. Could not be returned to vendor because it was exactly what the purchase order specified.

But it did great in the fuel tank for my 351 Cleveland engine in a '74 LTD with more than a 100k on the clock.

It is more likely that alcohol offered for sale is only tested if there is a complaint.

The Crown corporation says the recall was initiated after an investigation by its quality assurance team found the alcohol content was 77 per cent, instead of the 40 per cent declared on the label.

and there was a rush on the liquor stores before the bottles could be confiscated

Party pooper.
