(CNN.Money) - Brewers, vintners and distillers may have good reason to lift their glasses. Boozy benefits are tucked into the Senate tax plan.

Senate Republicans are proposing significant excise tax reductions for wine, liquor and beer -- including one that slashes in half the rate for craft brewers.

But the party could be short lived. Even if it passes, the proposed tax reductions are set to expire after two years.

"We're gratified to have achieved this and we're hoping to build on it in the future," said Mark Gorman, senior vice president for the Distilled Spirits Council, the industry group for the $65 billion liquor industry.

He said that he hopes to extend the reductions beyond two years.
