FLEX,® the flowable bittering hop product from John I. Haas and Barth-haas Group, meets brewing industry’s demand for increased profitability and sustainable practices.

YAKIMA, WASHINGTON, April 16, 2018 – After years of intensive R&D, John I. Haas, Inc. and the Barth-Haas Group are proud to announce that the innovative bittering hop product FLEX is now available for worldwide sale and distribution.

FLEX is a 100% all-natural hop product crafted to be pourable at room temperature, and to provide brewing flexibility and improved brew house efficiency. Even though it’s made using sophisticated processing technology, FLEX is actually just like fresh-squeezed hops. It’s convenient, easy to dose and typically offers brewers better than 10% increase in alpha acids utilization, when compared to hop pellets.

“Wort that’s bittered with FLEX provides a very clean canvas for aroma hops” said Virgil McDonald, Head Brewmaster at the John I. Haas Innovations Brewery. “We’ve been working closely with a number of brewers on FLEX, and the beers we’ve tasted have this great bitterness that is really clean and bright when you compare it to most other bittering alternatives.”

A critically important aspect of FLEX is improving process utilization. Whole hops and hop pellets are mostly vegetal material, which acts like a sponge and can result in significant wort loss, especially in today’s hop-forward IPAs. FLEX is a pourable liquid, so there’s no process loss, no waste handling or disposal of spent hops. And unlike CO2 extracts, FLEX doesn’t need to be preheated or pre-mixed with other liquids before it’s added to the kettle.

“As the craft brewing industry grows more competitive, the demand for more profitable and sustainable brewing practices has increased,” said Dr. Alex Byelashov, Vice President of Innovations at John I. Haas. “FLEX is a simple-to-use product that was developed by listening to brewers and understanding what they need to improve quality and efficiency.”

“Brewing great beer is our passion and our commitment,” said Tim Matthews, Head of Brewing Operations at Oskar Blues Brewing Company. “We’re also focused on bringing greater efficiency into our entire brewing and production processes. FLEX enables us to deliver on our brewing and business-related goals. It’s a great product.”

Continually striving to provide innovative new products in the hops industry, John I. Haas and the Barth-Haas Group are excited to be able to offer FLEX to brewers worldwide. To learn more about the benefits and advantages of brewing with FLEX, contact Roy Johnson or visit

Hop Products Australia (HPA) today launch their 2018 harvest season at their Victorian farm, Rostrevor Hop Gardens. To be followed closely by their Tasmanian location, Bushy Park Estates on Monday 5 March.

HPA’s farms have been growing hops since 1864 in Tasmania and for more than 120 years in Victoria. HPA is Australia’s largest hop grower, accounting for 90% of total hop production in Australia. One of only a handful of growers around the world committed to ongoing hop research and development of their own cultivars, this allows HPA to bring diverse and unique hops to brewers.

HPA Hop Harvest Fast Facts:

• 2018 Harvest will span five weeks
Seven Australian grown varieties will be harvested, consisting of Galaxy™, Ella™, Enigma™, Super Pride, Topaz™, Vic Secret™ and Cascade
300 seasonal workers will be helping with boots on the ground over this peak time
560 hectares are under trellis and to be harvested
• almost 20,000km of Coir twine has been deployed this season

HPA are expecting the 2018 harvest to yield an estimated 1,445 metric tonnes, which enables HPA to continue to supply proprietary flavour hops to the growing domestic and international craft beer markets. This forecast production represents an increase of 21% from the 2017 harvest and 100% increase over the last 4 years.

On the 2018 HPA harvest, Managing Director, Tim Lord says, “This is a very exciting time for us on farm and as a business, as HPA has recently invested heavily in order to see the operation and yield grow year upon year.”

“As Australia’s largest hop grower and supplier, we own and manage each step of the supply chain, from new variety development in the breeding garden, growing the crop, all the way through to final packaging and distribution. We’ve created the shortest path possible between farm and brewer, to deliver the highest impact in beer.”
