Infusing vodka is one part culinary science and one part liquid art. Unlike gin, which comes pre-loaded with botanicals, vodka is a blank canvas. By adding heat, you aren't just making a drink; you’re creating a versatile tool for cocktails like the ultimate Bloody Mary or a spicy Dirty Martini.
Here is everything you need to know to master the art of the infusion without turning your spirit into literal fire.
You don’t need the most expensive bottle on the top shelf, but you should avoid the plastic handles at the bottom.
The pepper you choose dictates the "personality" of your vodka.
Pepper Type | Heat Level (Scoville) | Flavor Profile |
Jalapeño | 2,500 – 8,000 SHU (Scoville Heat Units) | Bright, green, and grassy. Great for beginners. |
Serrano | 10,000 – 23,000 SHU | Similar to Jalapeño but crispier and noticeably hotter. |
Habanero | 100,000 – 350,000 SHU | Tropical, floral, and extremely potent. Use sparingly. |
Thai Bird’s Eye | 50,000 – 100,000 SHU | Sharp, biting heat. Perfect for savory cocktails. |
Dried Arbol | 15,000 – 30,000 SHU | Smoky, earthy, and nutty. |

Because vodka is high-proof (usually 40% ABV or 80 proof), it acts as a preservative. However, fresh peppers introduce water and organic matter.
Plain spicy vodka is great, but "Spicy Plus" is better. Try these combinations in your jar:

Making spicy vodka at home is a low-effort, high-reward project that beats any store-bought flavored spirit.
The key is vigilance – tasting the infusion regularly ensures you hit that "sweet spot" of spice without ruining the bottle.
Whether you're upgrading your brunch Bloody Mary or gifting a bottle to a heat-loving friend, the custom nature of DIY infusion is hard to beat.
