Some bottles of Bombay Sapphire in Canada give “extra” new meaning. The Canadian Food Inspection Agency recently found that a number of Bombay bottles have 77 percent alcohol by volume instead of the standard (and advertised) 40 percent alcohol by volume.

According to CNN Money, the agency only found a “small” number of 1.1 liter bottles with the upped alcohol. But the proof is all in the bottle.

The only reasonable advice for Canadians out there? Proceed with caution. No one has reported sickness from bad Bombay, but Bacardi, the company that owns Bombay Sapphire, put out a recall statement because of “an isolated consumer complaint and subsequent quality assurance checks.”

There’s reason to complain. The most common high-proof alcohol is Bacardi 151, and this gin is even stronger. This is some incredible, moonshine-level alcohol.

It’s not just a Bombay problem, either. It’s a Canada problem. This is the second time in two months that Canada has had a mislabeled, over proof alcohol on the shelves. In March, bottles of Georgia Bay Vodka were recalled for having a blindingly high (figuratively speaking) 81 percent alcohol by volume.

Check before you make that next Gin & Tonic, otherwise you might be in for a fiery surprise.
