The Slow Comfortable Screw Against The Wall is a drink whose name is also its recipe: Slow for sloe gin, Comfortable for Southern Comfort, Screw for the vodka-and-orange-juice Screwdriver underneath, and Against The Wall for the Galliano float borrowed from the Harvey Wallbanger. It is pure 1970s bar culture — a punchline you can drink — and, name aside, a genuinely pleasant fruity highball when made with fresh juice.
The whole recipe is in the name; the bartender just has to take dictation.
History
No creator, bar, or date is credibly documented — this drink emerged from the same 1970s American disco-bar scene that produced the Harvey Wallbanger and a hundred suggestively named shooters, and it spread because ordering one out loud was half the fun. The build is transparently modular: start from a Screwdriver, then bolt on sloe gin, Southern Comfort, and a Galliano float, each addition lengthening the name.
The family is large — drop the Galliano for a plain Slow Comfortable Screw, swap components for "Mexican" (tequila) or "Cuban" (rum) variants. The Wall version is the canonical maximal build.
The Spec
A tall glass of fresh orange juice carrying a split base: neutral vodka for push, sloe gin for berry tartness and color, Southern Comfort for peach-and-spice sweetness, and vanilla-anise Galliano floated on top so the first sip is louder than the rest.
Fresh Juice or Don't Bother
Four ounces of orange juice is the drink's entire midsection. Fresh-squeezed turns a novelty into a legitimately good brunch highball; carton juice keeps it a novelty.
The Galliano Float
Pour the Galliano gently over a bar spoon so it sits on top. That vanilla-anise first sip is the "against the wall" — stir it in and you've technically made a different (and less interesting) drink.
Bottom Line
Order it once for the name; finish it because sloe gin, peach, vanilla, and fresh orange juice is a combination that never needed the joke. Serve very cold, ideally somewhere with a disco ball.
