The presence at the golfing event, taking place at Castle Stuart Golf Links near Inverness from Thursday to Sunday, is the most recent in a string of successes for the beer-maker.
In May last year, Windswept Brewing was picked up by supermarket chain Waitrose, while a deal to supply the Co-op food business followed soon after.
Managing director Nigel Tiddy said: “We’re a really small brewery, so this is a fantastic opportunity for us to let golfers and fans from across Scotland in on the secret.
“The Scottish Open’s organising team’s decision to source and supply a local, quality craft beer should be applauded.”
Windswept is also aiming to double its annual production to 3,000 hectolitres and increase staff numbers from 12 to 17 within the next two years.
