Aissy Pourers,10 Pieces Stainless Steel Liquor Spirit Bottle Speed Pourers with Rubber Dust Caps for Wine,Juices,Acidic Drinks,Oil,Syrups,Vinegar,Spirits Rose Gold+Black

Excellent value for money. Great for balsamic vinegar and olive oil bottles

Have used these on both red and white wine bottles. Always check by upending the bottle and they do not leak.

I was bit worried about keeping bottles horizontally after putting the stoppers on. But these worked brilliantly...
