The actor poured the talk show host a glass of what he called “Diet Cokagne,” so of course, we set out to put it to the test.

In a video of the interview making the rounds on social media, Hanks set up the cocktail by filling two glasses about three-fourths of the way with Diet Coke.

The actor claimed that he chose the drink specifically because he has diabetes, but any Coca-Cola product would work for the concoction.

Now for the fun part — the millionaire filled the rest of the glass of cheap soda up with some expensive champagne.

“What’s better than Type II diabetes than a little shot of champagne in your Coke?” he joked.

“It’s like an American Aperol Spritz,” Colbert replied before the pair toasted and sipped.

The drink wowed Colbert, who claimed it was “refreshing” with a caffeine kick.

Needless to say, I ran out to get the ingredients.

At the liquor store, the cheapest champagne was $50, but that was too rich for my blood — especially to mix with soda.

Instead, I grabbed some sparkling wine for an “everyman” version — hey, we don’t all have Tom Hanks’ budget.

Back at home, I added some ice to a glass and filled it about three-fourths of the way up.

Next, I poured in the alcohol and noticed the immediate fizzing as the drink met the soda layer.

Taking a sip, I racked my brain to try to see what Colbert meant by “refreshing” when the drink tasted half-baked to me.

The concoction didn’t taste much like anything except a tad bit sweeter champagne, with a weird aftertaste from the sugar alternatives in the Diet Coke.

More than anything, I was relieved I didn’t shell out $50 to dilute a bottle of champagne like that.

Love you, Tom, but best to stick to acting rather than bartending.
