Breweries are being forced to get creative and spend big money to survive a crippling nationwide shortage of liquid carbon dioxide.
Since the end of refining at Marsden Point last year, the Kapuni carbon dioxide plant has been supplying the gas.
However, it's shut indefinitely for maintenance.
Co-Founder of small Wellington brewery Garage Project, Jos Ruffell told Tim Dower beer production relies on CO2 for cleaning, sterilising, and packaging beer, and to operate the taps the drink is poured from.
He says the company has made significant investment in capture recovery technology, so they can re-use any gas naturally produced during the fermentation process.

Are You A Charlotte?
In 1997, actress Kristin Davis’ life was forever changed when she took on the role of Charlotte York in Sex and the City. As we watched Carrie, Samantha, Miranda and Charlotte navigate relationships in NYC, the show helped push once unacceptable conversation topics out of the shadows and altered the narrative around women and sex. We all saw ourselves in them as they searched for fulfillment in life, sex and friendships. Now, Kristin Davis wants to connect with you, the fans, and share untold stories and all the behind the scenes. Together, with Kristin and special guests, what will begin with Sex and the City will evolve into talks about themes that are still so relevant today. "Are you a Charlotte?" is much more than just rewatching this beloved show, it brings the past and the present together as we talk with heart, humor and of course some optimism.
