The 3.9% abv beer, which is named Edinburgh Festival after the world-famous event, is a light session ale described as having a "gentle, refreshing bitterness".
The Stewart's team explained that a liberal dose of New Zealand hops to give the beer a citrus and pine aroma, which Stewart's say is "perfect for taking in the festival".

The Edinburgh brewer will also take up residence at the Pleasance Courtyard and Teviot Square this year, alongside Williams Brothers and Drygate Brewery, serving a selection of their popular craft beers.
The brewery’s popular Edinburgh Gold will also be served at the Edinburgh International Book Festival for the third year running, while various festival pop-ups will also stock Stewart Brewing favourites.
Jo Stewart, Stewart Brewing co-founder, who stated that the brand is excited to be doing so much during this year's Festival, said: “We’re all getting excited for the festival and we’re thrilled that our Edinburgh Festival ale will be available again this year.
"It’s proved really popular with festival goers in previous years so we thought we’d bring it back to avoid any disappointment.
“As an Edinburgh brewer, we’re really proud to be involved in the festival, particularly as it celebrates its 70th anniversary, and hope it’s another fantastic year for everyone.”
The Edinburgh Festival Ale will be available at a number of bars throughout the Festival including the Halfway House, Blue Blazer, Alexander Graham Bell, Bow Bar and Royal McGregor.
