297: Glorious Ontario Wines and the Stubborn, Pathological Optimists Who Make Them with Matthew Gaughan

Why do Ontario winemakers need to be exceptionally unreasonable, stubborn, and pathological optimists? Which Ontario wines should you try next, other than Icewine? Why should Ontario be at the top of your list of wine regions to visit? In this episode of the Unreserved Wine Talk podcast, I'm being interviewed by Matthew Gaughan on Matthew's World of Wine and Drink. You can find the wines we discussed at https://www.nataliemaclean.com/winepicks   Highlights Where is Ontario located, and what are the major wine regions within the province? What is the Ontario wine growing season like? When were Ontario’s first wineries established, and how has the industry developed since? What is the history of Icewine in Canada, and how is it made? Which notable Ontario white wine varieties should you try? How do Ontario Riesling and Sauvignon Blanc compare to other regions? Which unforgettable red wine varieties produced in Ontario should you try? What should you know about the sparkling wine scene in Ontario? How much of Canadian wine is exported, and what are some of the challenges faced by the industry? How is wine sold and consumed in Canada? What are some of the must-try experiences when visiting Ontario wine regions? How do Canadian wine producers promote their wines abroad?   Key Takeaways Why do Ontario winemakers need to be exceptionally unreasonable, stubborn, and pathological optimists? They need to brave our climate because humid summers can cause rot and mildew, rain right before the grapes are harvested, which, of course, can dilute the flavour, and then winters that can kill the vines. As one winemaker once told me, you can lose the whole field in an afternoon—a whole year’s work. Which Ontario wines should you try next, other than Icewine? Riesling is the number one white grape variety in Ontario, and it’s really undervalued. Everybody knows Chardonnay as a brand name and feels safer with It, but once they try Riesling, they realize how much flavour they’ve been missing. Why should Ontario be at the top of your list of wine regions to visit? First, it has stunning scenery and landscapes. Many wineries have restaurants so they offer delicious pairing menus. There are lots of other activities to do as well.   Join me on Instagram, Facebook and YouTube Live Join the live-stream video of this conversation on Wed at 7 pm ET on Instagram Live Video, Facebook Live Video or YouTube Live Video.

There's nothing that will put readers to sleep more quickly than a this happened, then this happened narrative. The mistake of underestimating the difficulty of navigating a dual timeline.

The mistake of believing that memoir is more closely aligned to non-fiction than fiction. A memoir is a true account but the techniques of memoir are all on the fiction side of things - plot, character development, climax and conflict.   About Ottawa Independent Writers Ottawa Independent Writers (OIW) was formed in 1986 as a venue for people with a passion for creating fiction and non-fiction, for writing poetry and plays, and for stringing words together in a variety of other formats.

292: Why Wildfire Smoke Taint in Wine Intensifies as it Ages with Dr. Wes Zandberg

Should we, as consumers, be concerned about buying wines from regions which have experienced wildfires? Why does smoke taint intensify as a wine ages? How can wineries mitigate the risk of producing smoke-tainted wine? In this episode of the Unreserved Wine Talk podcast, I'm chatting with researcher Wes Zandberg. You can find the wines we discussed at https://www.nataliemaclean.com/winepicks   Highlights Why does smoke taint show up differently in different wines despite the same level of exposure of the grapes? How can wineries mitigate the risk of producing smoke-tainted wine? Is there a health risk associated with wine made from smoke-exposed grapes? Why does smoke taint intensify with wine aging? Why does the perception of smoke taint become stronger with every sip? What are some similarities and differences between wildfire smoke exposure and the smoky aromas achieved with oak barrels? Are some grape varieties more susceptible to smoke taint than others? What are some of the main challenges in researching the effects of smoke exposure on wine? Were there differences between the wildfires in BC, California, and Australia wine country? Where is the current research focus for prevention and mitigation of smoke taint? How would routine testing of grapes in vineyards help researchers establish benchmarks for risk assessment? How could understanding more about the terroir of the air positively impact the wine industry?   Key Takeaways Just because a wine region is experiencing wildfires or even smoke drift from fires farther away, it doesn’t mean that the wine will be tainted. Smoke taint gets worse as wine ages because the wine develops new, more subtle tertiary aroma compounds which may be bolder. Australia has pioneered techniques such as making Rosé that’s not fermented on skins where the taint is. Smoke taint is less problematic for white wine because it too isn't fermented on skins.   Join me on Instagram, Facebook and YouTube Live Join the live-stream video of this conversation on Wed at 7 pm ET on Instagram Live Video, Facebook Live Video or YouTube Live Video.

Mario Pinto. Wes loved the rainy Fraser Valley so much that he remained at SFU, completing his post-doctoral research with Prof. David Vocadlo.

291: How Wildfires Affect the Taste of Your Wine with Dr. Wes Zandberg

What are the main causes of wildfires in wine country? Which two weather-based factors are the strongest predictors of the severity of wildfires each season? What impact do wildfires have on the taste of your wine, and why is it difficult to predict whether smoke-exposed grapes will, in fact, produce tainted wine? In this episode of the Unreserved Wine Talk podcast, I'm chatting with researcher Wes Zandberg. You can find the wines we discussed at https://www.nataliemaclean.com/winepicks   Highlights What sparked Wes’ interest in winemaking and wine chemistry? Why are BC wineries at a disadvantage coming out of 2022 and 2023? What are the main causes of wildfires in British Columbia? How much damage was caused by the wildfires in late 2023 and why were they worse than in the past? Why did the wildfires start so early in 2024? Which two weather-based factors are the strongest predictors of the risk of wildfires each season? How does fire play an important role in the forest ecosystem? How do wildfires affect wine itself chemically? What is the economic impact of wildfires on the wine industry? Why is it challenging to predict smoke taint through analytical tools alone? How does yeast activity contribute to smoke taint in wine post-fermentation?   Key Takeaways In 2021, Wes notes that the BC’s Okanagan Valley experienced severe wildfires due to arson. The vast majority, though, of wildfires are started by lightning and human causes, both errors and malevolence. Wes observes that the quicker snow melts and evaporates, leaving drier conditions, the greater the risk of wildfires. This is exacerbated if seasonal rains are below average, especially in June and July. There isn’t a chemical test to determine whether smoke-exposed grapes will actually produce smoke-tainted wines. Smoke taint also doesn’t express itself in unfermented grapes, making it even harder to predict its impact on the wine.   Join me on Instagram, Facebook and YouTube Live Join the live-stream video of this conversation on Wed at 7 pm ET on Instagram Live Video, Facebook Live Video or YouTube Live Video.
