Hi Darwin, thanks for sharing this. You’re right that the same spout can behave a little differently between the 8 oz and 16 oz bottles. The difference comes down largely to bottle geometry and the way air has to enter the bottle as the oil leaves it. The 16 oz bottle tends to allow that exchange more smoothly, while the smaller 8 oz bottle can be a little less forgiving, particularly when tipped quickly or at a steeper angle. We’ve found that a slower, more controlled pour with the 8 oz bottle helps maintain a cleaner stream and reduces oil collecting around the spout. That said, we don’t want you losing product every time you use it, so we appreciate you pointing this out. We’ll continue evaluating the spout with both bottle sizes.
