# Wine Upcycling Projects Rewine by Buvons Nature Turns Its Leftovers into Food By Adam Harrie | Written with AI assistance | Published 2026-05-07 | Eco Source: Trend Hunter, https://www.trendhunter.com/trends/buvons-nature References: [thedrinksbusiness](https://www.thedrinksbusiness.com/2026/04/nothing-wasted-taiwans-circular-wine-revolution/)  Rewine, a collaborative initiative linked to Taiwan’s Buvons Nature fair, repurposes [winery leftovers into new food products](https://www.trendhunter.com/trends/eat-wasted), featuring collaborations between winemakers and local artisans. The project uses grape pomace and lees in creations such as freeze-dried pomace chocolate and lees-washed cheeses, designed to preserve varietal character and reduce waste. The article reports the initiative as an ongoing rollout led by figures including wine expert Yusen Lin and chocolate maker Wilma Ku. Participants experiment across formats: Ku freeze-dries pomace to infuse artisan chocolate, Weightstone diverts fine lees to a washed-rind cheesemaker, and small-batch fermented tofu and salami incorporate lees as an active starter. Trials also test [piquette revivals](https://www.trendhunter.com/trends/wonderwerk) and coffee fermented with millet or wine lees, revealing supply and scale challenges. For consumers, Rewine demonstrates how [small-scale circular systems](https://www.trendhunter.com/trends/by-osmosis) can create premium, locally distinctive products while raising the profile of Taiwan’s young wine sector. The effort matters because it pairs traditional fermentation know-how with product innovation, producing niche goods that can command higher prices and promote sustainable practices.
