Taco Bell's Duo Habanero Sauce Arrives October 6, Free With a Doritos Locos Taco and $0.20 After

Duo Habanero Sauce is a limited-edition sauce packet made for Taco Bell's collaboration with Duolingo, and the company says it was created exclusively for it. Taco Bell describes it as bright and tangy with fruity notes and a kick of habanero heat. No ingredient list was published, so this page does not carry one.

The packets themselves are the point of the collaboration. Taco Bell prints short sayings on its sauce packets, and for this run those sayings appear in nine languages — English, Spanish, French, Hindi, Portuguese, German, Korean, Mandarin and Japanese. The company says packet assortments outside the U.S. will reflect the local language along with some of the most popular languages Duolingo users are learning in that market.

In the U.S. the sauce is free with the purchase of a Doritos Locos Taco, limited to one complimentary packet per qualifying order, and additional packets are listed at $0.20 each. That price carries a caveat from Taco Bell's own footnote, which says to check the store for price and participation, both of which vary. So $0.20 is the figure the company published, not a guarantee of what any given restaurant charges.

The sauce has a start date and no stated finish. It launches October 6, 2026 at participating restaurants in the U.S., Canada, Australia, China, India, Spain and the UK, and the release qualifies that with "while supplies last". Taco Bell named no last day, so there is no end date on this page; a limited-edition sauce tied to a single day could be gone within the week or run for longer, and the company has not said which.

The free month of Super Duolingo is where the announcement disagrees with itself. The body of the release says Taco Bell Rewards members can unlock it "From October 1 through October 6". One footnote agrees, stating the offer "Ends 10/6/26 or when supply of codes is depleted, whichever occurs first". A second footnote, attached to the same offer, instead says it "Ends 10/13/26 or when supply of codes is depleted". Both footnotes agree on the rest: codes must be redeemed by November 15, 2026, and stay active for 30 days after activation.

That is a contradiction inside a single official document rather than a disagreement between outlets, so there is no better source to break the tie. Anyone planning to claim the Duolingo month should treat October 6 as the deadline, because it is the earlier of the two dates the company gave and the one its own body copy states. The offer also carries conditions: it is for Taco Bell Rewards members in good standing who are not already Duolingo subscribers, and it cannot be combined with another Duolingo extended free trial in the same calendar year.

The sauce is one piece of a one-day event. Taco Bell says 1,000 Taco Bell x Duo plushies — Duo in a custom Taco Bell uniform with a mini headset — are available across participating markets worldwide. In the U.S. they are awarded through a sweepstakes rather than sold: Taco Bell Rewards members enter on October 6, 2026 at 2 p.m. PT, no purchase necessary, open to members aged 16 or over who are legal residents of the 50 U.S. states or D.C., while supplies last. The company says fans in the UK, Canada, India, Australia, China and Spain get their own chances through local activations.

There is also a physical event. Taco Bell says Duo and company will work a one-day takeover at the Taco Bell Midtown Cantina, 976 6th Ave, New York, on October 6 from 3:00 p.m. to 4:30 p.m. ET, handing out swag and giveaways while supplies last. Three further activations run the same day: an in-store event at Phoenix Marketcity Mall in Mumbai, a takeover at 252 Church Street in Toronto, and an event at 55 Century Avenue in Shanghai.

All of it is scheduled for a single date, which is unusual enough to be worth stating plainly: the activations are not a window, they are an afternoon.

Taco Bell has spent several years reshaping National Taco Day, and the company lays out that history in the announcement itself. In 2022 it turned the day into a month with the Taco Lover's Pass. In 2023 it campaigned to open up the phrase "Taco Tuesday" for other restaurants to use. In 2024 it worked with National Day Calendar to move National Taco Day itself to the first Tuesday in October — which in 2026 falls on October 6, the date of this launch. In 2025 it marked the first anniversary of the moved date with deals.

Taking the day international is the next step in that sequence, and the premise the company builds the campaign on is linguistic: Taco Bell says the word "taco" stays nearly the same across more than 30 languages. Luis Restrepo, Chief Marketing Officer of Taco Bell North America, said in the announcement that "the fact that 'taco' is understood in more than 30 languages proves just how universal it is". Emmanuel Orssaud, Chief Marketing Officer of Duolingo, said that "taco is a rare word that travels easily across cultures, making it a fun starting point for getting people curious about language". Amy Ellis Durini, Chief Marketing and Strategy Officer of Taco Bell International, said there is "something pretty special about a word that can be understood across languages and cultures".
