There are a bunch of horchata flavors. Here are some notes I made on some of them. All of them are probably too cinnamony for what OP wants, unless he wants it for a cereal milk situation and the cereal is a cinnamon cereal.

LA Horchata - Cinnamon, pennies, flowers, and cream. Subtle but strange cinnamon - a bit coppery and a bit floral at the same time, with a soft vanilla cream. I think that floral edge to the cinnamon is supposed to be rice, but it’s battling with the cinnamon up top and coming across as touch of weird flowery perfume instead. It’s mostly soft, kind of fluffy vanilla cream with a dry, bland finish.

OoO Horchata - Red Hots soaked in vanilla almond milk. Cinnamon on top is overpowering and very much Red Hots candy. Underneath is a very nutty vanilla milk. The juxtaposition of that strong candy cinnamon with such a nutty milk is weird and kinda gross.

TFA Horchata - Hot Damn. It tastes like taking a double shot of Hot Damn cinnamon liqueur and chasing it with half a shot of vanilla milk. If you need a Hot Damn flavor and don’t mind a little vanilla milk behind it, this will do. If you looking for Horchata, forget about it.

FW Horchata - Part cinnamon, part red hots, with vanilla cream. The cinnamon stops short of full on candy but still tastes like something bright red versus a real bakery cinnamon. It sits on top of a bright vanilla cream in about 50/50 split, so the cinnamon is a bit much, but it has a sweet, smooth finish. There’s a little something grainy behind the cinnamon but it’s just barely present before getting overwhelmed by a Tahiti-type vanilla and doesn’t really taste like rice water or rice milk. Cinnamon comes back in the finish and tastes a little more like actual cinnamon than it does at first. I’m not tasting anything that should offend someone who doesn’t hate red hots or vanilla, but I don’t have the patience to try to figure out what to do with this.

CAP Horchata - It tastes about like what you’d expect CAP Horchata to taste like. The cinnamon upfront tastes just like the cinnamon in CAP Graham Cracker and about the same strength, too, so the cinnamon is fairly light. It tastes fine to me but I’m sure it comes across as a little metallic to some people, since CAP Graham Cracker and Cinnamon Danish Swirl do. Heavy French-type vanilla milky sweet cream under it, with some somewhat nutty maybe rice-ish flavor kind of hiding behind the vanilla. Very thick, very smooth. Might need some help both the cinnamon and rice departments to get a more authentic Horchata but seems like a versatile option for cinnamon + vanilla cream.

TFA Horchata Smooth - Not bad. Tastes like TFA realized they fucked up on the original Horchata, tried to correct it, and mostly succeeded. The cinnamon is more natural and relaxed, though a little dry and not very rich, without much depth. It tastes like the same cinnamon as their Cinnamon Sugar Cookie but instead of a nondescript dry bakery, it sits on top of and mostly dominates a vanilla that’s creamy, sweet, smooth and starchy, if not blatantly rice-y. So the balance is off, with too much cinnamon, but it’s not a nightmare, and the vanilla has a thick mouthfeel. The starchy sort of bready aspect is subtle enough that it seems like it could work anywhere you want cinnamon, vanilla, and cream.

FLV Horchata- Eating powdered Horchata mix without adding water first? It’s not actually so dry as a powder, but it’s pretty dry for something that’s supposed to be a beverage. The rice water flavor and cinnamon are both present and realistic, as well as well-balanced. The cinnamon up front tastes like dilution-level amount of FLV Rich Cinnamon, like the cinnamon note in FLV Apple Filling, but with rice water instead of apple. Deeper, thick body with some voluminous cream like a little milk added, maybe almond milk because there’s some nuttiness poking out behind everything else, but not much. Cinnamon type/level dead on for horchata, along with a nice light sweetness. It is a bit harsh for the amount of cinnamon you get out of it. And despite the cream flavor, again, quite a bit dry on the end for something that’s supposed to be a beverage. Besides using it as a horchata, could see it working in a cinnamon cereal and milk type of situation and with the rice taste being fairly subtle, maybe any kind of bakery for slightly starchy volume with a bit of cinnamon. I want to see what happens if I mix it with one of the more realistic graham cracker flavors and see if I get something like CAP Graham Cracker but with a better, richer bakery cinnamon.
