According to the They found sulfur-containing compounds, thiophenols, in the smoke-impacted wine and determined they contributed to the ashy flavor, along with “volatile phenols,” which Australian researchers identified as factors more than a decade ago. Bush fires have long impacted Australia's wine industry. Up in Washington state, Collins confirmed that the sulfur compounds were found in the wine that had been exposed to smoke in the Oregon vineyard but weren't in samples that had no smoke exposure.
