According to the browser compatibility table of the official MDN documentation, the CSS variables feature is widely available in all popular browser versions released after April 2017. More specifically, browsers released this feature with the following versions:

Google Chrome 49 (Released 2 March 2016)
Microsoft Edge 15 (Released 5 April 2017)
Mozilla Firefox 31 (Released 22 July 2014)
Apple Safari 9.1 (Released 21 March 2016)

According to these statistics, using custom properties in production apps is possible since most users nowadays use up-to-date web browsers. However, it would be prudent to analyze your audience’s browser versions before using any new native CSS feature.
