In May 2017, retail clothier, H&M, used Nancy & Lee's version in their "The Summer Shop 2017" ad campaign and as a result, the track debuted at #1 on Billboard magazine and Clio's Top TV Commercials chart for May 2017.
Lyrically, "Summer Wine" describes a man, voiced by Hazlewood, who meets a woman, Sinatra, who notices his silver spurs and invites him to have wine with her. After heavy drinking, the man awakens hungover to find his spurs and money have been stolen by the mysterious woman; the subtext of which being they experienced intercourse and as payment she took his "silver spurs, a dollar and a dime". He then declares a longing for more of her "wine". One interpretation is that the man singing the song was seduced by the woman in order to steal his money and belongings. Another interpretation, sometimes cited, is that the song contains an allegorical description of drug use and that the lyric "she reassured me with an unfamiliar line" specifically refers to cocaine though that is anomalous for the apparent period setting.
The song was later covered by Demis Roussos with Nancy Boyd, The Corrs featuring Bono of U2, Ultima Thule, Gry with FM Einheit and his Orchestra, Anna Hanski & Lee Hazlewood, Scooter (on the 2000 album Sheffield), Jack Grace and Moimir Papalescu and The Nihilists (with the male and female parts switched). A cover version by Ville Valo & Natalia Avelon, recorded for the soundtrack of Das Wilde Leben, was the 4th best-selling single of 2007 in Germany and was certified Platinum by the BVMI.
