Syrup
Flavor Name: Vanilla
The Torani Vanilla Coffee Syrup is a great value and a nice, generous size. The vanilla flavor is smooth and works well in coffee and other drinks. I really appreciate that it comes with a pump—it makes dispensing easy and mess-free once it’s set up.
However, it’s important to note that when you first insert the pump into a new, full bottle, the syrup can spill over due to the displacement. I recommend placing the bottle in the sink or removing a small amount of syrup before inserting the pump.
Overall, a solid product with great flavor and convenience, just be cautious during the initial setup.

Makes delicious iced coffee!
Flavor Name: Vanilla, Flavor Name: Vanilla
Im someone who likes their coffee to actually taste like coffee and I love this syrup. I’ve been making iced coffee at home almost daily lately, and this vanilla syrup is the only one I keep reaching for. The flavor is smooth and sweet without tasting artificial, and it actually tastes good in iced drinks instead of getting lost in the coffee. The pump also makes it really easy to use without the sticky mess.
My current go-to drink:
• 2 pumps vanilla syrup
• Double espresso pod
• Pour over lots of ice
• Splash of almond milk
• Finish with brown sugar creamer
Your bank account will thank me!!!

Syrup is excellent, the pump is dramatic
Flavor Name: Vanilla
I am marking 5 for the syrup itself, my favorite syrup.
In regards of the pump, a little too dramatic for me and it will go everywhere. I would rather pour the syrup, including I found the pump will leak and there was a ring of syrup around the base of the bottle. Perfect for a coffee shop, but not for a basic kitchen....but I am picky about syrup splattering because the sugar ants are a nightmare.

GREAT GRAPE FLAVORED AND INCREASED ENERGY
Set name: Welch's Grape
I have tried the competitor’s grape flavored versions.
This is by far the best grape flavored energy drink.
It gives you the increased energy level you’re looking for without making you feel “fidgety.”
Highly recommend this energy drink for its effectiveness and flavor!

Green Apple is the best!
Set name: Warheads Sour Green Apple
Love these, I am subscribed for every two weeks, they last me one a day at work until the next shipment. Yay! Green sour apple is just the best. It’s slightly sour and refreshing. I work graveyard and stay awake all night with one of these. Super effective, great value for the money since I’m getting them cheaper this way than buying one a day at the convenience store next to my house. They’re sugar free but use sucralose, which is wannabe sugar but still, I’d say better for me (pre-diabetic) than real sugar.
