Give the jalapeño time to steep

The interesting aspect of jalapeños (and other chili peppers) is that their spiciness can vary based on their ripeness. A jalapeño that is still green will have a milder taste compared to a fully matured, bright red one. You can choose either for your spicy rosé, but if you opt for the red-hot variety, exercise caution when adding it to your drink.
Avoid diving into your spicy rosé immediately after incorporating the jalapeño. Doing so may result in an intense burst of chili flavor with your first sip, as the capsaicin will still be seeping from the jalapeño and accumulating at the top of the drink. This could lead to an uncomfortable moment of coughing and watery eyes, which is certainly not the impression you want to make or what most would consider enjoyable.
Instead, here’s a helpful tip: After adding the jalapeño, gently stir your drink and allow it to sit for at least five minutes (you can let it steep for up to an hour). This resting time enables the alcohol to absorb the jalapeño's spicy essence and evenly distribute it throughout the drink. The result will be a perfectly balanced spicy rosé, where each sip delivers just the right amount of heat to keep things exciting without overwhelming your palate.
Other tricks to make your spicy rosé tastier

When you slice open a jalapeño, you'll discover a cluster of seeds at the center of the fruit. You probably don’t want those seeds floating around in your drink. Just remove the seeds before adding the chili to your rosé. If you’ve already included the jalapeño, no need to panic — you can always strain the drink to get rid of any stray seeds.
While the seeds are fair game, be sure to leave the ribs intact! These are the white, fibrous membranes that line the inside of the pepper. This is where most of the heat-producing capsaicin is found, so if you remove them, you’ll miss out on a significant amount of heat that could enhance your spicy rosé.
Of course, this is assuming you want to maximize the heat from your jalapeño. If you prefer a milder drink with less spice, opt for a green (less ripe) jalapeño and remove both the seeds and the ribs. This way, you can enjoy a trendy drink without overwhelming your taste buds with heat.
