Fits 200mL, 375mL, and 750mL bottles. Simplify the dispensing of your favorite Olive Oils and Wine Vinegars by using a Weighted Pour Spout. Designed to help control the flow, the green and white pourer is weighted to automatically open when tilted downward for pouring and closes when turned upright. The flexible rubber seal provides a secure fit on 200mL, 375mL, and 750 mL bottles. We do not recommend this pourer for our balsamics as they are too thick to pour through the small tube. Use the Dripless Pour Spout for Balsamics.
