Registration Statement on Form S-3

Ladies and Gentlemen:

We have served as special New Jersey counsel to Bai Brands LLC, a New Jersey limited liability company (the “New Jersey Guarantor”), in connection with the issuance and sale by Keurig Dr Pepper Inc. (the “Company”) of $1,150,000,000 aggregate principal amount of the Company’s 0.750% Senior Notes due 2024 (the “2024 Notes”), $500,000,000 aggregate principal amount of the Company’s 2.250% Senior Notes due 2031 (the “2031 Notes”), and $500,000,000 aggregate principal amount of the Company’s 3.350% Senior Notes due 2051 (the “2051 Notes” and, together with the 2024 Notes and the 2031 Notes, the “Notes”), covered by the Registration Statement on Form S-3 (File No. 333-233477) and Post-Effective Amendment No. 1 (File No. 333-233506) (together, the “Registration Statement”), including the prospectus, dated August 27, 2019 and the prospectus supplement constituting a part thereof, dated March 1, 2021 (the “Prospectus”), filed by the Company with the Securities and Exchange Commission under the Securities Act of 1933, as amended (“1933 Act”). We have represented the New Jersey Guarantor in connection with certain transactions on matters relating to New Jersey limited liability company law, but do not generally represent the New Jersey Guarantor nor act as its regular outside counsel.

The Notes were issued under the Company’s Indenture, dated as of December 15, 2009 (the “Base Indenture”) between the Company (or its corporate predecessor) and Wells Fargo Bank, N.A., as trustee (the “Trustee”), supplemented from time to time thereafter, including by the eleventh supplemental indenture, dated as of March 15, 2021, among the Company, the Subsidiary Guarantors (defined below) and the Trustee (the “Eleventh Supplemental Indenture,” and together with the Base Indenture, the “Indenture”). The Notes were sold by the Company pursuant to the Underwriting Agreement, dated as of March 1, 2021, among the Underwriters named therein, the Company and the subsidiary guarantors named therein (the “Subsidiary Guarantors”), including the New Jersey Guarantor. The Notes provide that they are fully guaranteed (the “Guarantees”) by each of the Subsidiary Guarantors. For purposes of our opinions set forth herein, we have assumed, with your consent and without investigation, the correctness and accuracy of the opinions, dated this same date, of Skadden, Arps, Slate, Meagher & Flom LLP.

In connection with rendering the opinions contained in this letter, we have examined originals or copies, certified or otherwise identified to our satisfaction, of such documents, corporate records, agreements, certificates of public officials and other instruments and reviewed such questions of law as we have deemed necessary or appropriate for the purposes of the opinions contained in this letter, including the following documents:

This opinion letter is based upon the customary practice of lawyers who regularly give, and lawyers who regularly advise recipients regarding, opinions of the kind rendered in this opinion letter.

We have assumed the genuineness of all signatures, the legal capacity of natural persons, the authenticity of all documents submitted to us as originals, the conformity to original documents of all documents submitted to us as copies (whether or not certified, and including facsimiles), and the authenticity of such latter documents. We have also assumed that the Indenture has been duly authorized, executed and delivered by the parties thereto and that the Indenture is the valid and legally binding obligation of the Trustee. Capitalized terms used but not defined in this letter have the meanings contained in the Prospectus.

In rendering the opinion set forth in Paragraph 3 above as to the delivery by the New Jersey Guarantor of the Indenture, we have assumed with your permission that (a) the laws governing such delivery if other than New Jersey law are substantially similar to the laws of the State of New Jersey and (b) electronic transmission of the Indenture has been authorized by the parties to the Indenture for purposes of delivery.

We are members of the Bar of the State of New Jersey and we do not express any opinion herein governing any law other than the law of the State of New Jersey nor with respect to choice of laws. This letter speaks as of its date, and we undertake no (and hereby disclaim any) obligation to update this letter.
