Love the flavor in my coffee.
Flavor Name: Vanilla
This taste so good and adds delightful flavor to my coffee. I love the pump on the bottle. I love the size of the bottle. It is a great price and quality all the way around. It mixes very well with my coffee. It lasts well, since you don't need much. I love the syrup, it is not watery.

Vanilla Syrup
Flavor Name: Vanilla
So tasty. Put in my ice coffee and it is perfect. Large bottle but just the right size for me using it daily. Highly recommend.

Wonderful for London Fogs
Flavor Name: Vanilla
This was a really good-tasting product! I personally use it to make London fogs, and it is perfect for this goal of mine. I do think the pump doesn't spray the syrup as "laminar" as I would like, which causes it to splash onto the table around my mug, but it's still a solid product despite this issue.

Will always make coffee with this
Flavor Name: Vanilla
This is the key to a good coffee! I do 3-4 pumps and my coffee is sweet & tasty. Bottle is large and will last a while as I don’t make coffee daily. The pump makes life so much easier. Great taste, highly recommend :)

Perfect
Flavor Name: Vanilla
I got this vanilla syrup for my wedding to use at a soda bar, and it was such a hit! Everyone loved it. The flavor is amazing—smooth, sweet, and really rich without tasting artificial. It added the perfect cozy touch to the drinks and worked so well with everything on the menu. I’m so glad I chose this one, it tasted incredible and made everything feel extra special!
