I tried this with much hesitation as I have a very sensitive palate and cake vapes tend to taste too much like baking extracts to me, almost like that alcohol-y taste. That is not the case with this cake vape. It tastes just like vanilla sponge. It is very vanilla heavy but I don't mind it. ON the first inhale of this flavour, I think my taste buds didn't know what to make of it, partially because I was just coming off an extremely sweet strawberry juice.. As I got used to the vanilla, the yellow sponge started to come through more and the flavour developed. By the end of the first few hours of vaping this, I loved it. It's different from any flavour of tried, and I've gone through many many bakery/cake/dessert flavours.. To get a sense of my flavour profile, Loaded glazed donuts is my favourite all time all day vape. I also like Wonutz Strawberry vanilla glazed and Blonut milk. I would say that Castella is a really nice ADV. Beautiful rich and vanilla-y cake comes through in many different ways and it's the perfect amount of sweetness. It allows you to really enjoy the full flavour of the juice with out it becoming sickly like many other dessert vapes. For the price on here, I'd say it's definitely worth a try and one of the better ones in the Koi range.
