Red berry
Size: 16 OZ
Upon arrival I looked at them and didn’t think they were going to be good. Turned out they’re delicious. They were sweet, huge , and very fresh.

La freza es la frescura de las frutas
Size: 16 OZ
Strawberries are not merely a natural dessert; they are one of the densest sources of antioxidants and Vitamin C available. Their perfect balance of acidity and sweetness makes them the ideal ally for those seeking low-calorie energy.

Tastes Like Banana Pudding and Dunkin Banana Flavor!
Flavor Name: Banana Bread, Size: 25.4 Fl Oz (Pack of 1)
I don't know why someone would buy this expecting it to taste like real bananas like come on ppl lol. The only way to attain a syrup that tastes like real banana bread is to make it at home. This is an artificially flavored syrup so obviously it tastes that way! I have made banana bread syrup (more like a sauce) at home and it is delicious, highly recommend!! But this is way more shelf stable and tastes amazing in an iced latte as well! Different than home made but still good. To me this tastes like banana pudding mix which also has a fake banana taste. It also tastes EXACTLY like the new Dunkin banana flavored syrup which is what I was looking for! I use 1.5 tbsp syrup, a little vanilla paste, 2 espresso shots and 2 percent milk with plenty of ice. I like keeping my latte calories below 200 and not super sweet tho so you can up it to 2 tbsp. The cals in this are not terrible, 70 cals for 2 tablespoons. Usually my syrups have 50-60 cals for only 1 tbsp so I'm pleasantly surprised this is a little lower. I bought a second bottle because I'm afraid this is a limited release lol.

⭐ DaVinci Gourmet Classic White Chocolate Syrup Review
Flavor Name: White Chocolate, Size: 25.4 Fl Oz (Pack of 1)
The DaVinci Gourmet Classic White Chocolate Syrup is a must‑have if you love café‑style drinks at home. It delivers that rich, creamy white‑chocolate flavor without being overly sweet, and it blends beautifully into both hot and cold beverages. Whether you’re upgrading your morning latte or adding a touch of sweetness to desserts, this syrup is incredibly versatile and delicious.
🍫 Why This Syrup Stands Out
Smooth white‑chocolate flavor: Creamy, mellow, and perfectly balanced — not artificial or overly sugary.
Great for hot & iced drinks: Mixes easily into lattes, iced coffees, frappes, hot chocolate, and even milkshakes.
Barista‑quality texture: Silky and consistent, making it easy to drizzle, blend, or layer.
Large 25.4 oz bottle: Plenty of syrup for daily use, entertaining, or experimenting with new recipes.
Versatile beyond drinks: Works beautifully in baking, frosting, oatmeal, and dessert toppings.
☕ Perfect For
Homemade lattes and cappuccinos
Iced coffees and cold brews
White‑chocolate mochas
Dessert drizzling
Smoothies and milkshakes
Holiday drinks and creative recipes
It adds that cozy café sweetness without overpowering the drink.
🔍 Things to Keep in Mind
Because it’s a classic syrup (not a sauce), the flavor is lighter and more mixable — great for drinks, but those wanting a thick drizzle may prefer a white‑chocolate sauce.
A little goes a long way, so start with a small amount and adjust to taste.
⭐ Final Thoughts
The DaVinci Gourmet Classic White Chocolate Syrup is a creamy, smooth, and incredibly versatile addition to any coffee or dessert routine. It elevates homemade drinks with a professional touch and adds just the right amount of sweetness. If you love white‑chocolate‑flavored coffees or want a reliable syrup for everyday use, this bottle is an excellent choice.

✪ DaVinci | Gourmet Classic Vanilla Syrup: Great Flavor, Uses Cane Sugar, Great Price...
Flavor Name: Vanilla, Size: 25.4 Fl Oz (Pack of 1)
✪ DaVinci | Gourmet Classic Vanilla Syrup, 25.4 fl. oz. (Pack of 1)
_____________________________________________________________________>
♦♦ Vanilla Syrup:
● I wanted to reduce the amount of flavored coffee creamer
that I normally use, so I thought I would give DaVinci syrups
a try. This was the first time that I tried and used the DaVinci
brand.
♦♦ Coffee Time:
● I used about half of the coffee creamer that I typically use
and I added a teaspoon or two of DaVinci syrup to my morning
coffee. I gave it a good stir, then took a few sips and there was
plenty of flavor for my liking and it seemed to have a rounder
and had more of a vanilla like taste when comparing it to the
vanilla flavored coffee creamer that I normally use, I definitely
enjoyed the result.
♦♦ Great for Other Uses:
● I also tried this syrup with other drinks such as soft drinks,
cola, orange and root-beer, and a smoothie. All of them of
them were very good, indeed. Give it a try.
● I also added some to plain yogurt and some other foods and
they all tasted really good as well.
♦♦ Ingredients:
Cane Sugar, Water, Natural Vanilla Extract with Other Natural
Flavor, Sodium Benzoate and Potassium Sorbate (preservatives),
Citric Acid, Caramel Color.
✪ Pricing: $6.88 / 25.4 fl. oz.
● A very affordable price for it's size, especially when compared
to other brands that I've had before.
✪ SCORE: 5 Stars > ⭐ ⭐ ⭐ ⭐ ⭐
♦ ✪ ♦ Over-All:
● I most definitely liked the results that I got when using DaVinci
flavored syrup with my coffee, soft drinks (soda) and even food.
As affordable as it is I would recommend checking it out and see
what you can come up with. I would buy it again.
