• 413: Hop Scientists Megan Twomey and Ryan Christian Share the Latest on Virus-Free Hops

  At the turn of the 21st century, it wasn’t uncommon for a hop grower focusing on alpha varieties to replant a field every 25 to 50 years. While the plants in the field inevitably contracted viruses, the impact of those viruses on alpha-acid development and overall yield was manageable. In today’s environment, however—with new varieties bred to be high-performance, high-aroma, well-oiled machines—the same viruses have an outsized effect, and a field’s lifespan may be just a quarter of what it used to be. Yet many growers have been extending the productive lives of those fields by planting virus-free rhizomes and plugs—plants grown from cuttings taken from portions of other hops plants where viruses can’t travel. In this episode, we talk with scientists and hop breeders Megan Twomey of Latitude 46 (https://latitude46.com) and Ryan Christian of Yakima Chief Ranches (https://yakimachiefranches.com) for perspective on how viruses affect hops, how virus-free plants are produced, how long plants can remain virus-free, and more—and how all of that ultimately affects what’s available to brewers. Through the conversation, they touch on: different viruses that affect hops how viruses affect lupulin production in modern hop varieties viral impact in producing genetically true-to-type but phenotypically out-of-spec hops “cleaning up” hops to create virus-free plants how and now not to monitor fields for viruses field dynamics from new plantings over the first few years how viral stress impacts plants and their flavor and aroma expression yield benefits from virus-free plantings And more.

• 412: Colt Carpenter of Pax Verum Sources Intentional Ingredients for Nuanced Beers

  Over the past two years, five beers that Lapel, Indiana’s Pax Verum (https://www.paxverum.com) sent to Craft Beer & Brewing Magazine for review have scored 95 or above. That naturally piqued our interest, so when we planned our Craft Brewers Conference itinerary we made sure to visit the hip outpost an hour north of Indianapolis. Head brewer and co-owner Colt Carpenter cut his teeth working in a homebrew shop before making the jump to the world of professional brewing, and his embrace of high quality and diverse ingredients tracks with that experience of assisting home brewers with their own ingredient choices. Now, he embraces everything from traditional English styles and European lagers to cutting-edge IPAs, but always with a slight contemporary edge. In this episode, Carpenter discusses: building a wider understanding of and familiarity with beer ingredients by working at a homebrew shop sourcing ingredients intentionally with flavor in mind designing robust porter around a specific specialty malt managing challenges with craft malt like increased friability and seasonal variation focusing on freshness while managing color swings with specialty malts avoiding over-oxygenation cool pooling IPAs with flowable hop products building depth in hoppy beers without T-90 pellets finding hop lots that meet flavor goals, without selecting unique flavors and aromas from Michigan-grown varieties And more.

• 411: Matt Warner of Parrotdog Takes a Counterintuitive Approach to Hops in Classic, Bright, and Hazy IPA

  Parrotdog (https://parrotdog.co.nz) has been a craft-brewing mainstay in New Zealand for nearly 15 years, and with national distribution and a production brewery and taproom steps from the beach and Wellington’s airport, they reach a broad audience of consumers across a range of styles. While their core line features everything from a classic C-malt IPA to pils with “vivid passion fruit and white-wine notes,” they also constantly iterate and experiment on the brewery’s five-barrel pilot with everything from fresh-hop lagers to saturated hazy IPAs. This week, cofounder and brewing director Matt Warner joins the podcast to talk hops (of course) and how they employ both domestic and Pacific Northwest varieties across a range of styles. Along the way, he discusses: growing from a contract brand to a small brewery to a regional production brewery scaling from homebrew recipes to commercial batches in the early days designing “zingy” New Zealand pils that snaps across and cleans the palate rebalancing blends of Riwaka and Nelson Sauvin yearly to adapt to crop-year differences how Motueka changes over the picking window with a bit of “ginger crunch” character instability in Motueka after pelletizing using hops to build bigger mouthfeel in otherwise dry beer new Bract Program experimental hops that show promise And more.

• 410: NZ Grape Ale? All-Riwaka Pils? Fork & Brewer’s Brayden Rawlinson Applies European Influence to Local Ingredients

  In Wellington, New Zealand, the Fork & Brewer (https://forkandbrewer.co.nz) has to live up to a reputation, and head brewer Brayden Rawlinson is up for the challenge. Under the leadership of previous head brewer Kelly Ryan (now with Freestyle Hops), the downtown brewpub garnered numerous awards, and the expectations placed on his successor were huge. Yet Rawlinson brings his own style and swagger to the role, alongside a deep love of fermentation in all its forms, and he’s continuing the legacy with different takes on beer that are equally medal-worthy (https://brewersguild.org.nz/2024-nz-beer-awards-winners-announced/). In this episode, Rawlinson discusses: pressure fermentation at warmer temps for faster, pub-centric lagers that win medals brewing pils with 100 percent Riwaka hops added everywhere, from mash and first wort through a dip-hop addition and dry hop achieving a more herbal, Noble-like character with Riwaka sculpting a slightly drier NZ pils applying Italian-style method to beers made with New Zealand Sauvignon Blanc grapes and Nelson Sauvin hops balancing the acidity in wine-grape beers with low pH but not overt sourness And more.

• 409: NZ Pilsner in Perspective with Paweł Lewandowski of Mount Brewing

  While hop-forward lager may be a relatively new phenomenon in the States, New Zealand brewers have been brewing their own version of pilsner for decades using homegrown hops. Yet threading the needle in a precise style with hops that can have strong notes, such as mineral and diesel, is no small feat. In this episode, Paweł Lewandowski, the award-winning head brewer at Mount (https://mountbrewingco.com) in Mount Maunganui, on the North Island, walks us through the creative and technical process behind their “beer geek pilsner”—a beer that multiple brewers recommended to us as a standout example of the style. Motueka, Nelson Sauvin, and Riwaka work together in a golden ratio with two pilsner malts, wheat malt, actively managed fermentation temperatures, and concise lagering to produce a pilsner with 45 IBUs and a full body that expresses the more structured side of the country’s signature hops. During the episode, Lewandowski discusses: the style’s origin, beginning with Emerson’s (https://emersons.co.nz) in the 1990s building a heftier body with pilsner and wheat to support strong hopping his experiments with step-mashing that led back to single-infusion using Motueka, Nelson Sauvin, and Riwaka at various points during the boil, whirlpool, and dry hop year-over-year flavor variation in New Zealand hop varieties balancing selection criteria to work across a range of styles warmer lager fermentation, with a 24-hour temperature drop early on lower pH and shorter lagering times for bright, hop-forward pils contrasts between New Zealand and West Coast pils using the “golden ratio” for hop blends And more.
