And you feel like having a drink.

There's vodka, gin, rum, lemonade,

but this would all be a mistake.

Because in this city, you have to indulge in a glassful of Hungarian history.

Well, actually, three to be exact.

Meet Pálinka, Unicum and soda water.

Without further ado, let's bring in our experts.

First up, Zoltan

who heads up the House of Hungarian Pálinka in Budapest.

Pálinka is a strong spirit.

It is 100 percent fruit distilled.

Pálinka is deeply woven into the fabric of Hungarian society.

Everybody knows what it is.

And the history of Pálinka began in 1300s

when the Queen and the King of Hungary were all suffering from gout.

They stumbled upon this earlier version of Pálinka,

which they used to cure themselves.

It is made from a huge variety of fruits,

apricots to plums to cherries to pears to apples.

Now we've heard it's quite strong.

The usual alcohol content is typically between 40 and 50 percent,

some of them 60 percent.

Some of them even higher.

Can your Unicum beat that, Sándor?

We can't beat it, but we can match it

because we also have 40 percent.

Really, Unicum is a bitter herbal liquor;

there's roughly 10 million Hungarians,

and we sell yearly 4 million bottles.

It was invented in 1790 by my ancestor.

I am the sixth generation.

See this Dr. Zwack was the physician to the Emperor of Austria-Hungary.

And when the Emperor had a bad stomach.

My ancestor made him Unicum,

which is made of 40 different kinds of herbs and spices.

The recipe's a secret, so I can tell you that,

for example, we use vanilla or ginger.

OK, I told you two.

That's enough.

And for you non-drinkers, there's soda water.

A staple on Hungarian tables.

This is László and his father.

Thank you, gentlemen.

My name is László Kiss, and I am a soda water maker.

The fact is we don't use many ingredients, only carbon dioxide and water,

but the different ways of mixing, how much water with how much carbon dioxide,

and also how much pressure you fill these bottles with is crucial,

so you have to pay attention.

No wonder László knows his stuff.

It was in Hungary where the large scale production of soda water started.

Ányos Jedlik invented it in the 1820s, and the consumption of soda water has boomed since then.

I think anyone who feels Hungarian inside starts to smile when they see a soda water bottle.

Shall we taste them?

Bottom's up, gents.

- That was strong. - That's a good drink. - That was great.
