Is a Vesper shaken or stirred?
Bond famously ordered it shaken. At home, I prefer stirred for a clearer, silkier drink. If you like it extra cold and a touch more diluted, shake it hard for 10 to 12 seconds, just know it will turn a bit cloudy from aeration.
What is Lillet Blanc, and can I substitute it?
In the original Vesper, Fleming called for Kina Lillet. The exact original formula is not available today (it was reformulated and the old version is essentially gone), so modern bottles of Lillet Blanc are the usual stand-in: lightly sweet, citrusy, and floral.
If you cannot find Lillet Blanc, use Cocchi Americano in the same amount (1/2 oz) for a more Kina-like bite, or use dry vermouth in a pinch. If using dry vermouth, try 1/3 oz to start and adjust to taste next time.
What gin works best?
London Dry is the safe move. Think crisp, juniper-forward styles. If your gin is very floral, the drink can lean perfumey fast, so keep the lemon twist and do not overdo the Lillet.
What glass should I use?
A chilled coupe or martini glass is perfect. A Nick and Nora is great too, especially if you like a smaller pour that stays cold from first sip to last.
How do I make it less strong?
This is a strong cocktail by design. For a gentler version, stir a bit longer for more dilution, serve it smaller, or drop the total spirit amount by about 25 percent and keep the Lillet proportion the same.
What is the classic ratio?
Purists often point to Fleming's spec as roughly 3:1 gin to vodka plus Kina Lillet. This recipe is a scaled house version that stays in the same neighborhood but fits modern glassware without overflowing.
