It's been added to many dishes, recipes and beverages. But move over guacamole – an avocado beer has been brewed in Bay and is making its way to Katikati's A&P Show this Sunday.

Yes, the creamy, buttery tones of avocado have been infused into a brew in a Mount kitchen to showcase the region's avocado producing efforts in a novel way.

And it will offer A&P show-goers free 60ml samples at the Avocado in the Katikati Avo Expo section of Uretara Domain this Sunday, February 5.

The man behind the brew is Stu Marshall, who owns Rocky Knob Brewing Company with wife Bron.

Stu was handed the peculiar task of making an avocado beer from avocado company Southern Produce's marketing manager Mike Swan.

'Someone within the organising committee for the Katikati Avo Expo came up with an avocado beer – after they'd been to an avocado festival in America,” says Stu.

'Mike basically said: ‘We need a beer with avocado in it'. So we've done a complete and utter trial of it.

Had Stu ever heard of an avocado beer before? 'No,” he laughs. 'So I kind of just thought what is going to work and what is the flavour profile of an avocado? Which is kind of nutty and buttery.”

'So I made a Saison beer, which is Belgian-style beer, which has got flavour to it from the yeast you use.”

As owner of Rocky Knob brewing company, Stu develops all their recipes and helps manufacture his beer using other equipment from other breweries.

'So this avocado beer has been made in our pilot brewery kitchen at the Mount.”

He started off making a Saison beer base – and instead of using hops in the fermenter, when the beer has nearly finished fermenting, Stu has used guacamole to flavour it.

'So the Saison base itself I have put in some phenolics, spices and stuff as yeast flavouring.

'And we've tried to back it up by adding what we thought would be an interesting guacamole mix.”

Stu says the guacamole mix included avocado, fresh coriander, lime juice, onion and garlic.

'Everyone goes: ‘Guacamole, yep avocado' – so it actually gives the avocado a bit of flavouring profile.”

'It's a guacamole Saison as such.”

Stu says he basically treated the guacamole as dry hop. 'So the beer had nearly finished fermenting when we put the guacamole mix in – so it's been about a 10-day process.

'Now we've put the beer in kegs and have had a taste testing. Everybody gave it the seal of approval. The general consensus of the interested onlookers was it's okay as well.

'So it's going to be an alright brew.”

So will Stu pursue making avocado beer in future? 'Quite possibly. If it's a success as such it might be something we do as a seasonal beer on occasion, probably in conjunction with the Southern Produce guys, who supplied the avocados for it.”

And Stu says the beer is definitely a novelty – he's amazed by how much publicity it's created so far.

'The Katikati Avocado Expo committee wanted to do something different to show that avocados have many different uses as such – this is not as simple as making a guacamole and spreading it on your toast.”

'It's a different way to consume the avocado, says Stu.

Mike says if nothing else – the beer has triggered an enormous amount of interest in the avocado expo at the show.

'It may have an avocado flavour people will recognise, while others may miss it.

'The craft beer industry has grown massively and it was a chance to mix the two.

'Our biggest concern now is we won't have enough – it's a good problem to have.”

The Katikati Avocado Expo is at Katikati A&P Show this Sunday, February 5. Gates open 9am.
