Grolsch is a Dutch brewery founded in 1615 and best known for its swing-top bottles, whose porcelain stopper and rubber seal produce a distinctive pop when opened. That mechanical release became a familiar pub and kitchen sound, and short recordings of it circulate online as a reusable effect. Creators lift the isolated pop for videos about drinks, unboxings and celebrations, where a recognisable bottle opening is needed without recording one themselves. Its brevity and clear attack keep it popular for edits that need instant, physical feedback.
