Zirkova
Canadian brand of Ukrainian vodka

Zirkova is a Canadian brand of vodka distilled in Zolotonosha, Ukraine, and headquartered in Oakville, Ontario. Established in 2005 by John and Katherine Vellinga, the company initially produced vodka under the Slava and Zirkova labels before discontinuing the former. Twice seeking funds through the Dragons' Den television series, the company was valued at CA$10 million by 2012. Zirkova experienced reduced sales during the COVID-19 pandemic. After the 2022 Russian invasion of Ukraine, Zirkova began to donate profits to humanitarian projects in Ukraine; it also developed an Ontario-distilled product.
Several Zirkova products are sold, including Zirkova One for sipping and Zirkova Together for cocktails. Sales are primarily concentrated in Ontario through the Liquor Control Board of Ontario, though the product is also distributed in Western Canada.
History
Establishment
Zirkova ("starry", from the root зірка) was established by John and Katherine Vellinga, a couple who had met while studying engineering the University of Waterloo. John, born in Waterloo, Ontario, learned about vodka from Katherine's Ukrainian-Canadian family. The couple worked as consultants in Ukraine beginning in 1997 before returning to Canada in 2002.

Why this record matters
“Zirkova” is worth following because a concise public description often conceals a longer documentary argument. Here, Zirkova, Canadian and brand provides the most credible route into that argument.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated May 19, 2026. The linked authority identifier is Q138846018. The first chronological checks are 2005, 2012, 2022 and 1997.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
