Double, double, toil and trouble;
Fire burn and cauldron bubble.
Round about the cauldron go;
In the grilled pineapple and bacon throw.
Breweries in the Southern Highlands have summoned the wackiest and tastiest concoctions for the GABS festival.
The Great Australasian Beer Spectapular will feature 180 beers brewed specifically for the occasion.
More than 11,000 people attended the festival in 2018.
Owner of Eden Brewery, Jacob Newman, said all of the beers entered on the night must never have been made before.
"The competition provides the opportunity to do something new and creative," Jacob said.
The beer expert said the popularity of the event ensures he will sell out of stock.
"It takes away the financial pressure," Jacob said.
The first year Eden Brewery participated in the festival they created a pistachio cream ale.
The Mittagong based brewers used hundreds of kilograms of pistachios for the project.
"I quickly realised it was a great way to burn money," Jacob said.
Jacob said this year they wanted to be more impressive and developed a grilled pineapple and smoked bacon IPA.
"It's common to add fruit to IPA," Jacob said.
The Eden Brewery team took inspiration from smoked beer made from malt barley dried over an open flame.
"We decided to merge the two together," Jacob said.
The concoction called for more than 100 grilled pineapples and an astronomical amount of bacon juice.
Cooking juices from bacon oven-baked at the Press Shop were collected and filtered for the brewery.
Jacob said the resulting product was pure bacon essence that gave the beer a distinct smokey flavour.
The beer will be embargoed until June 2, when it is sure to fly off the shelves.
