Can I use Yellow Chartreuse instead of green?

You can, and it will be a different, gentler drink. Yellow is lower proof, sweeter, more honeyed and less aggressively herbal. It makes a lovely, easygoing version. But the Champs-Élysées earns its reputation on the green, with that resinous, almost medicinal kick cutting through the Cognac. If you go yellow, pull back the simple syrup, because yellow brings its own sweetness to the party.

What Cognac should I actually buy for this?

A solid VS or VSOP. You do not need to crack open something you'd save for a snifter, because the lemon and the Chartreuse will trample subtle barrel notes anyway. A workhorse VSOP gives you enough fruit and oak to stand up to the green onslaught without making you cry over the cost. Save the XO for drinking neat while you judge people.

Why does mine taste like cough syrup?

Too much Chartreuse, almost certainly, or not enough acid to balance it. The fix is more fresh lemon and a steadier hand on the green stuff. Keep the Chartreuse at three quarters of an ounce, no heavier, and make sure your lemon is squeezed that day. Bottled lemon juice is the single fastest way to make any sour taste like regret.

Champs-Élysées: The Cognac Sour That Drank Too Much Chartreuse

Somewhere between the Sidecar and a monastery, there is this drink. The Champs-Élysées takes Cognac, hits it with lemon, and then does the reckless thing: it pours in Green Chartreuse, the most opinionated liqueur ever made by monks who won't tell you the recipe. The result is a sour with a green, resinous undertow that sneaks up around the third sip. It is named after the grandest avenue in Paris, and for once the name is not overselling.

1.5 ozCognac

0.75 ozGreen Chartreuse

0.75 ozLemon Juice

0.5 ozSimple Syrup

1 dashAngostura Bitters

Garnish: Lemon twist

You shake this, hard, over good ice, and you do it because there is citrus in the glass and citrus needs aeration to wake up. Cognac as the base, three quarters of an ounce of Green Chartreuse, three quarters of fresh lemon, a half ounce of simple to keep the peace, and a single dash of Angostura to give the whole thing a spine. The Chartreuse is the variable that ruins amateurs. It is 55 percent alcohol and tastes like a forest floor distilled by people who pray, so it will bully everything in the glass if you let it. Three quarters of an ounce is the ceiling. Past that you are drinking liqueur with a lemon problem. Use fresh lemon, never the bottled stuff that smells like furniture polish, and cut the simple syrup if your Chartreuse leans sweet. Double strain into a chilled coupe so no ice shards float on top. Express a lemon twist over the surface, drop it in, and leave the rest of the theater to somebody else.

This is a Sidecar, structurally, wearing a green coat. The Sidecar family is the daisy template: a spirit, citrus, and a liqueur that does double duty as both sweetener and flavor. In a classic Sidecar that liqueur is orange. Here it is Green Chartreuse, sitting at three quarters of an ounce, never overpowering the Cognac base. That ratio is the whole game. The liqueur stays at or below the base spirit so the drink reads as a sour first and a flavor showcase second. Get the proportions right and you understand the entire family in one glass: the Aviation, the Cable Car, the Brandy Crusta, the Bramble, all of them spirit and citrus held in balance by a structural liqueur doing the talking. The Champs-Élysées just happens to lead with brandy and the loudest liqueur on the shelf, which makes it the family's most dangerous member to mix by feel.

The drink shows up in the Savoy Cocktail Book in 1930, Harry Craddock's era, when London bartenders were quietly catching every American who fled Prohibition with a thirst and a passport. Nobody can prove who invented it, which is the honest answer for most cocktails from that decade. What we know is that it belongs to a brief, civilized moment when Cognac was still a serious base for mixed drinks rather than a thing rappers buy by the case. Chartreuse has been made since the 1730s by Carthusian monks in the French Alps, and they still make it, and they have famously refused to scale up production to satisfy a market that suddenly decided it was cool. That refusal is the most punk thing happening in the liquor business. The Champs-Élysées rewards that stubbornness. It is herbal without being a chore, boozy without being a stunt, and old-fashioned in the good way, the way a well-kept bistro is old-fashioned. Order it in a bar that knows what it is and you have found a bartender worth tipping.
