Can I use prosecco instead of Champagne?
Yes. Champagne is classic, but prosecco is budget-friendly and totally delicious here. Just know that prosecco sweetness varies by style. If you want it crisp and not sweet, choose Brut (or Extra Brut if you can find it). If your prosecco leans fruitier or sweeter, use slightly less simple syrup.
Do I have to shake it?
Shaking chills the drink and adds the right dilution fast. If you are batching for brunch, the easiest move is to pre-chill the base in the fridge, then shake each drink to order. If you really want a no-shaker option, you can add a small measured splash of cold water to the batched base for dilution (instead of stirring a whole pitcher with ice), then top with sparkling wine in the glass. Just avoid adding sparkling wine to the pitcher.
What is the best gin for a French 75?
A classic London dry works great. You want juniper and citrus notes, not heavy barrel flavors. If your gin is very floral, keep the garnish simple so it does not get perfumey.
How do I make it less strong?
Use 1 ounce gin instead of 1 1/2 ounces, then top with a little more sparkling wine. It stays balanced and feels lighter.
What is a French 125?
Some people use the name French 125 for the same drink made with cognac instead of gin. You will also see it listed simply as a French 75 with cognac (and a few other numbers, depending on the menu). Either way, it is richer, warmer, and very good for cold-weather brunch or holiday dinners.
Can I make it without simple syrup?
You can, but plain sugar does not dissolve easily in a cold drink. If you are in a pinch, use 1 to 2 teaspoons of superfine sugar and shake longer, or swap in maple syrup for a cozy twist.
