How long does liquid smoke last?

[Ryan Burke]

Was not sure where to put this thread so I decided here. I use a little bit when I make BBQ sauce but could not find an expiration date on the bottle. I bought a new bottle but my last one I probably used for 5 years.

From one manufacturer's website:

What is the shelf life of Colgin Natural Liquid Smoke?

We guarantee Colgin Natural Liquid Smoke's freshness and flavor intensity for two years. However, because of Colgin Natural Liquid Smoke's low pH and antimicrobial properties, it is often safe and delicious for twice that long.
