Winemakers increasingly acknowledge impacts of climate change, but the topic is sensitive

Climate change is a touchy topic for winemakers, who are wary of casting doubt on the vintages they produce. But many are now acknowledging that temperature spikes and weather extremes are affecting what they grow and bottle.

Climate change is "like a train coming through the tunnel at you," says Harry Peterson-Nedry, a winemaker in Oregon's Willamette Valley. "The light from the train may help you a bit in seeing where you are walking. But eventually you will get crushed."

Though winemakers may have been a little slow on the uptake when it comes to climate change related droughts, soaking winters, heat waves and wildfires, it seems beer brewers are already adapting to changing conditions and even trying to reduce their carbon footprint.

• In the ongoing effort to 'Keep Portland Weird' and create a lower-carbon beer, Baerlic Brewing and the Oregon Environmental Council teamed up to create a bike-powered mill to grind the malt for its "Bike Crush Saison".
• Not to be outdone, the Danish beer icon Carlsberg announced plans to reduce its brewery carbon emissions to zero by the year 2030. It's worth noting that Donald Trump's decision to withdraw from the Paris climate agreement inspired this worthy goal. Tusind tak, Donald!
• This article from Nexus Media claims that in fact, beer is the greenest beverage, as breweries seek to become ever more sustainable. This includes the Chico, California craft brew giant Sierra Nevada, which has integrated conservation into every step of production.
• Finally, Scottish beer producer BrewDog is raising awareness about global warming in its "Make Earth Great Again" campaign, in which it is fermenting a 'protest beer' at a higher temperature, as a 'metaphor for global warming'.
