"I've tried using pourer spigots and a solenoid but the air intake caused leakage issues. Ended up using a peristaltic pump and food safe silicone hose. The spout is a stainless spigot. Dropping the silicone into the bottle ensures spillage is kept to a minimum. We also artificially aged the oak cask used to house the project. A quick video of the project is here: https://www.instagram.com/p/BLtLstTgOI1/"
