The other day Blake brought in an aquarium pump to make rye whiskey air. The basic concept of using an aquarium pump to create bubbles is simple. Plug the pump in, regulate the air flow of the pump to create air bubbles. The air was made using rye whiskey, simple syrup, and 1.5% lecithin. The ingredients were sheered well using a vitaprep. Now usually I have seen and used handmixers to sheer the mixture to form stable air bubbles. By using an aquarium pump fitted with a rock diffuser you can create bubbles that have a larger structure to them. Now common physics tells you that the smaller the air bubble the more stable the final mix will be. Using lecithin in your recipe will help in emmulsification as well as the stabilization of these air bubbles. The air itself had great flavor release. It tasted pretty close to taking a shot of whiskey. The bubbles were stable for about 5 minutes or so before they began to deflate. By using the aquarium pump you achieve a very unique looking bubble that not only looks visually appealing but also tastes great. Below are pictures of the aquarium pump blake used, and the rock diffuser. The videos show first the bubbles created using the rock diffuser in water and then the rock diffuser being submerged into the rye whiskey mix creating large stable air bubbles.
