we wanted to find out all the differences

between Pepsi in the UK and the US.

This is "Food Wars."

In the UK, Pepsi comes in a range of portion sizes,

but these do vary slightly

depending on which type of Pepsi you're buying.

We used to be able to get mini cans,

but they've been discontinued,

so now you can get classic Pepsi in four portion sizes.

As a 330-milliliter can,

as a 500-milliliter bottle,

as a 1.5-liter bottle,

and as a 2-liter bottle.

In the US, our Pepsi comes in these following sizes:

The mini can is the smallest. 7.5 fluid ounces.

Next one up, the classic can, 12 fluid ounces.

Then we move up to plastic bottles.

This one is 16.9 fluid ounces.

Then we got the 20-fluid-ounce bottle.

And if that's not enough,

we go up to 1-liter bottle. Liter of cola.

Then moving up a little bit more, 1.25-liter bottle.

And then our biggest bottle is the 2-liter bottle.

We can also get glass bottles,

but like the classic can, they are 12 ounces.

Where regular Pepsi is concerned,

both countries cap out at a 2-liter bottle.

However, in the UK, we can go one step further

when it comes to diet and Max Pepsi.

Certain retailers, such as Iceland or B&M, stock these.

A 3-liter bottle of Pepsi Max or Pepsi diet.

We finally have something bigger than America! We did it!

I don't know if that's a good or a bad thing,

probably bad for the nation's health,

but, you know, nice to be different for once.

There are some other slight size differences

for the sugar and sugar-free options in the UK as well.

For example, in the UK,

we can get a 1.25-liter bottle of Pepsi Max or Pepsi diet,

which we can't get for the classic Pepsi.

The size differences are largely down to the UK's sugar tax.

It's a tax which raised the price of drinks

with more than 5 grams of sugar per 100 milliliters.

The higher prices reduce the demand

for the full-sugar versions of soft drinks,

making it less viable to sell them in large containers,

such as the 3-liter.

But don't worry, because you can still get sugary Pepsi

in bulk quantities.

Our largest bulk is the 36-can pack of Pepsi,

and that's the 12-ounce cans.

That is 432 fluid ounces of soda,

or 3.375 gallons, of Pepsi.

Now, that pack of cans is at least available at Sam's Club,

possibly Costco, I don't know, but I went to Sam's Club,

and unfortunately they would not let me buy it

without a membership.

So, the best I could do are these pictures

of me with the packs.

That is much larger than our largest option,

which is this, a 24-pack of cans.

Not only is our multipack

only two-thirds the size of the American one,

but the cans themselves are also smaller.

A can in the UK contains 330 milliliters,

while a can in the US contains 355.

This means that the total for our 24-pack

comes to 2.09 gallons.

Even if we had a 36-pack,

it would still be smaller than the American version.

We need three extra cans to make up the difference.

Here are all the Pepsi products you'll find in the UK

that you won't find in the US.

Here are all the Pepsi products from the US

you won't find in the UK.

We'll start with the exclusive flavors of Pepsi.

In the UK, we have Pepsi Max raspberry.

It's got that really comforting,

extremely nostalgic artificial blue-raspberry flavor

that you're used to.

On Pepsi's UK website, it also said they do lime Pepsi,

but I wasn't able to find that at any of the stores I tried.

Whoops.

We have a few exclusive Pepsi options of our own.

Starting down here, we have Pepsi real sugar,

which is in fact made with real sugar,

not the high-fructose-corn-syrup stuff.

Not bad.

We also have Pepsi mango and Pepsi mango zero sugar.

Seems like a weird fruit choice.

Whoa, smells good.

I'm surprised by how good this is.

And they got the mango zero sugar.

Ooh, already smells drastically different.

It's got a real chemically aftertaste.

Not as good as the regular.

This one here is

Pepsi soda shop cream soda.

Mm.

Very nice.

And the last one, Pepsi vanilla.

I'm gonna be honest with you, Pepsi,

could use a lot more vanilla.

It's, like, vanilla-kissed.

[burps] There it is.

All right, right now what I want to do

is compare the already-tasted real sugar Pepsi

to the regular Pepsi, which has high-fructose corn syrup.

Regular Pepsi.

[coughs]

Pepsi's harsher than Coke.

Yeah.

About to say something somewhat controversial,

but bring it, I want all the smoke.

Real sugar Pepsi tastes just like Coke.

It's just smoother.

This is like ... [burps]

Yeah, this is, like, harsher.

Joe was kind enough to send me some American Pepsi

as well as some real sugar Pepsi,

so I'm going to do a three-way taste test

and see if I can tell the difference.

Pepsi No. 1.

That's very, like, strong flavor,

quite a syrupy texture to it almost.

Pepsi No. 2.

Yeah, very sweet, but almost in a more gentle kind of way.

And then No. 3.

More similar in kind of, like,

I'd say sweetness and mouthfeel to the middle one.

This one is the one that stood out with the strongest taste,

in my opinion.

These two were very similar, which is making me think

that these are the British and real sugar Pepsis.

I'm not sure in which order,

but they had a more gentle taste,

whereas this one seemed harsher and tasted very syrupy.

So I'm going to guess British,

American real sugar,

American normal Pepsi.

I'm shocked.

These two tasted really similar to me,

and this one stood out, like I said,

and it wasn't particularly pleasant.

Maybe the UK needs to take a leaf out of America's book

and just put high-fructose corn syrup in everything.

The other exclusive Pepsi item in the UK

is this Pepsi SodaStream syrup.

For the uninitiated, a SodaStream is a device

which lets you carbonate your own drinks at home.

Now, as a sparkling-water obsessive,

I actually own one of these.

So we're going to make our own Pepsi.

So, what you do

is you get one of your little SodaStream bottles,

fill it to the first line, and attach it to the machine.

Then you press this button, and the magic happens.

According to this bottle,

you add about half a cap of the syrup to this.

That's quite cool.

The first thing I get is just Pepsi.

It tastes a lot like Pepsi Max.

There is a slightly unpleasant aftertaste,

which, I'm not sure where that's come from.

Maybe I used too much syrup. Who knows.

But I think, yeah, in terms of recreating

a fizzy drink at home with not a lot of equipment,

it's pretty good.

And that's pretty much it

as far as Pepsi exclusives are concerned,

but we're not stopping there.

PepsiCo owns more beverage brands,

but it does differ depending on which country you live in.

Now, while in the US, Keurig Dr Pepper owns 7Up,

in the UK, it's actually owned by PepsiCo,

which means that technically

all of these are Pepsi exclusives.

British 7Up comes in four forms.

As classic 7Up, a 7Up Free, 7Up cherry Free,

and as a SodaStream syrup.

That's actually not bad.

It doesn't have the unpleasant aftertaste

that the Pepsi one did.

That to me just tastes like 7Up.

One other thing that's worth pointing out

is that in the UK, this is considered lemonade.

Like, if you walk into a pub or a restaurant

and ask for a glass of lemonade, this is what you'll get.

Like, a clear sparkling beverage.

Is that not the case in America?

That is definitely not lemonade,

and it is super weird.

Lemonade is lemon, not juice, right?

But you squeeze lemons in water and mix it up,

and it's, like, more refreshing and kind of tart.

And it's closer to a lemon juice.

It's definitely not carbonated.

In front of me we have something that's brand new,

and it is called Pepsi Nitro.

What is it? Wait, excuse me.

Nitro Pepsi, flip 'em.

Looks to be a tall boy of Pepsi

that, according to the can, is nitrogen-infused cola

with smaller bubbles and a smoother taste.

[drink fizzes]

Did you hear that? Oh, man!

That's a pretty hard pour, right?

It's not going crazy like a normal Pepsi would, right?

I'm more excited about the vanilla.

Let's really get really good audio on this one now. Ready?

[drink fizzes]

Hard pour.

Yeah, it's a little bit smoother.

It still tastes just like Pepsi.

Not as carbonated, which is fine.

Do the vanilla.

Much better. Ooh, that's nice. Yeah.

The issue I'm having with it

is that the only time soda is that "smooth"

is when it's flat.

I'll f--- with it, but it's just OK.

Pepsi has a few exclusive brands in the US,

including Mug Root Beer, Sierra Mist, and Bubly.

They're a carbonated-water brand.

Mug Root Beer.

I was the master at being able

to tell different root beers on taste.

I could tell them apart.

That information is, like, in my DNA.

One of these days we'll do a root-beer lineup,

a root-beer taste test.

I guarantee I will ace that test.

Yeah, it's taking me back.

Also, they got Sierra Mist.

I hate Sierra Mist.

It's a lemon-lime flavor.

I don't know if they're competing with Sprite or 7Up.

Always hated this.

Sprite is better. 7Up is better.

Sierra Mist tastes the way

fruit-flavored shampoo smells, if that makes sense.

[burps] OK.

This'll be my ranking system, from best to worst.

So, first we're going to go strawberry.

No, I do not like that.

Cherry.

I think these all might be bad.

That one's a little better than the strawberry one.

Pineapple.

Nope, woof!

Grapefruit, ugh.

Low expectations on this one.

Oh, my God, that smells like an armpit.

Oh, man, if I went into a public restroom

and it smelled like this, I would run out.

No!

Oh-ho-ho-ho-ho-ho-ho!
