Who makes Kirkland Signature Malbec (Mendoza, Argentina)?
As of July 5, 2026, the manufacturer of Kirkland Signature Malbec (Mendoza, Argentina) is Trapiche (Broquel Winery), per on-label, first-party, or executive statement evidence.
The common claim
What most answers say — and what the evidence supports
Wine reviewers and Costco-wine blogs agree on this one. Recent vintages of Kirkland Signature Malbec carry the back-label statement 'Produced and Bottled by Broquel Winery' and credit winemaker Sergio Casé — and Broquel is the value label of Argentina's Trapiche, where Sergio Casé is chief winemaker. So the Mendoza Malbec is a Trapiche product, bottled under its Broquel brand and imported to the US by Costco's négociant, DC Flynt MW Domaines & Estates. Older vintages did not disclose the producer, and Costco can change suppliers by vintage, so the back label is the check.

Every source is graded on the six-tier rubric and archived, so the citation holds even if the original moves or paywalls. The tier badge grades the source; the status grades our confidence in the maker.
Tier 4
Reviewer transcribes the 2024 Kirkland Signature Malbec back label: 'Crafted at the Broquel winery in Mendoza, this Malbec was produced especially for Kirkland Signature. -Sergio Case, Winemaker. Produced and Bottled by Broquel Winery. 14% Alcohol,' and adds 'It is imported by DC Flynt MW Domaines & Estates.' 'Produced and Bottled by' is the strong TTB producer statement (the named winery fermented the wine), and the reviewer notes Costco 'revealed the producer as Broquel Winery … several vintages ago' — a direct on-label producer identification for this product.
Tier 4
Producer roundup lists 'Kirkland Signature Malbec: Broquel Winery' and states 'The $7 Kirkland Malbec is made by winemaker Sergio Case from Broquel winery in Mendoza, Argentina' — independent tier-4 corroboration of the back-label Broquel / Sergio Casé identification.
Tier 6
Resolves the Broquel name to its parent: 'Five different varietal Broquel wines are made,' billed as 'Broquel Label Wines From Argentina's Trapiche Winery,' and 'Sergio Case, a fourth generation winemaker, is blending his experience … for Trapiche Winery.' Confirms Broquel is Trapiche's varietal label and Sergio Casé is Trapiche's winemaker — the resolution behind the Kirkland Malbec's 'Produced and Bottled by Broquel Winery' statement.
