Quick Summary

California wine grape growers have removed over 100,000 acres of healthy vineyards in recent years due to low demand and a historic drop in wine consumption. This trend is not unique to California, with experts citing similar issues in other major wine-producing countries such as France, Italy, Spain, Australia, Chile, and Argentina. According to industry estimates, over 1.2 million tons of wine grapes have been left to rot on the vine in the last two years alone, with more expected to be removed this year. The decline in consumption is attributed to a combination of factors, including the Canada-United States trade war and provincial bans on American alcohol.

Story summary

California wine grape growers have removed over 100,000 acres of healthy vineyards in recent years, with 1.2 million tons of wine grapes left to rot on the vine in the last two years alone. The reason behind this phenomenon is not disease, but rather a decrease in demand due to a historic drop in wine consumption. In California, which produces 80% of U.S. wine, low sales have led to a "reset" for the industry. This situation has been exacerbated by the Canada-U.S. trade war and subsequent provincial bans on American alcohol, including from Canada, where wine imports from the U.S. were previously significant. Economists like Mike Veseth specialize in global wine markets and note that this issue is not unique to California, but rather a broader trend affecting vineyards worldwide, including those in France, Italy, Spain, Australia, Chile, and Argentina.

🔮 There are nods to a Canadian TV success story — Tall, Dark and Hollander and “Russians Don’t Blush” — on the drink menu, and two guests ask a server to take a photo of them in the booth where Shane Hollander (Hudson Williams) and Rose Landry (Sophie Nélisse) shared fries in an episode of Heated Rivalry.

🔮 The rise of nicotine pouches among young non-smokers has been swift, and the medical community and policy experts are concerned about the implications. Public health experts attribute the growth of nicotine pouches to lifestyle marketing reminiscent of the tobacco advertising of the past — now banned in Canada — and social media, where influencers promote nicotine as a wellness hack. “The advertisements seem to appeal to, or are designed to appeal to, younger folk, and I think sometimes they’re portrayed as being an alternative to smoking a cigarette, and they’re implying that it might be safer,” says Dr. Michael Mak, a staff psychiatrist at the Centre for Addiction and Mental Health and an associate professor in the Department of Psychiatry at the University of Toronto.
