New and Improved Bartenders' Manual by Harry Johnson (1900, p.241) — Hot
- Dissolve the sugar with a little hot water.
- Add the brandy and fill up with hot water.
- Stir up with a spoon.
- Grate nutmeg on top and serve.
- Add a slice of lemon if the customer desires it.
Garnish: Nutmeg, optional lemon slice
- Nose
- Warm brandy and nutmeg create a familiar winter mixed-drink aroma, with lemon optional rather than defining.
- Palate
- This is a direct hot sling, softer and rounder than the whiskey equivalents but still clearly part of the same dressed warm-service line.
- Finish
- The finish is warm, softly spiced, and spirit-led.
- Summary
- A classic hot brandy sling preserving the plain but dressed warm-service branch.
The optional lemon shows how customer choice continues to shape even old family forms. These drinks are not rigid templates but service frameworks.
The key distinction from punch remains scale and directness. This is a glass-built sling, not a bowl or a more elaborately citrused hot punch.
