The common claim vs. the 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.

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.

Frequently asked

Who makes Kirkland Signature Malbec?
Recent vintages are produced by Broquel Winery, the value label of Argentina's Trapiche, and the back label credits Trapiche chief winemaker Sergio Casé: it reads 'Produced and Bottled by Broquel Winery.' The 100% Mendoza Malbec is imported to the US by Costco's négociant, DC Flynt MW Domaines & Estates. The Costco Wine Blog's producer roundup independently names 'Sergio Case from Broquel winery.'
Is Kirkland Malbec the same as Broquel or Trapiche Malbec?
It comes from the same house. Broquel is Trapiche's mid-tier varietal line, made by the same winemaking team (Sergio Casé), so the Kirkland Signature Malbec is effectively a Costco-labeled Broquel/Trapiche Malbec — though Costco specifies its own blend and price, so it is not necessarily an identical bottling of the retail Broquel Malbec. Trapiche is one of Argentina's largest and most-awarded Mendoza wineries.
Has Kirkland always used the same Malbec producer?
No. Reviewers note that Costco only began disclosing Broquel Winery as the producer a few vintages ago; earlier Kirkland Malbec bottlings did not name a winery on the label. Recent vintages (through 2024) have carried the Broquel / Sergio Casé statement, but because Costco can change a private-label supplier between vintages, the reliable check is the 'Produced and Bottled by' line on the back label of your bottle.
