Who makes Kirkland Signature Sparkling Energy Drink, Variety Pack, 12 fl oz, 24-count?
As of July 5, 2026, evidence points to MPL Brands as the manufacturer of Kirkland Signature Sparkling Energy Drink, Variety Pack, 12 fl oz, 24-count, but no tier 1–3 source names the link directly.
The common claim
What most answers say — and what the evidence supports
When Costco launched Kirkland Signature Sparkling Energy Drinks (200 mg caffeine, sugar-free, orange/tropical/peach), shoppers widely speculated they were repackaged Celsius or were made by Monster. The evidence does not support that: Costco's own product catalog lists the manufacturer-of-record as MPL Brands (mfName 'MPL BRANDS NV INC'), a California beverage company - not Celsius or Monster. Trade coverage frames the Kirkland line as a private-label competitor that rattled Celsius, not a Celsius product. Because the catalog field can name a supplier-of-record rather than the physical co-packing plant, the attribution is graded probable.

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
Costco's product-detail page (item 1925833 / partNumber 4000444178) embeds catalog JSON whose manufacturer field reads: "mfName":"MPL BRANDS NV INC". This is the same catalog field that correctly resolves Kirkland diapers (FIRST QUALITY CONSUMER PR) and batteries (DURACELL DISTRIBUTING INC). Because mfName can name a supplier-of-record or brand-company intermediary rather than the physical co-packer, it grades probable, not confirmed.

Tier 4
"Through its private-label brand, Kirkland Signature, Costco launched a new line of energy drinks. Both companies now offer drinks using the same-size cans and the same amount of caffeine... Celsius shareholders are worried about the increased competition from this popular private label brand." Financial coverage frames the Kirkland line as a private-label competitor pressuring Celsius - notably not as a Celsius product - which supports debunking the 'it's just repackaged Celsius' theory. Does not itself name the co-packer.
