There's a bit of fruit to this grand Sam Adams experiment, but make no mistake -- the flavor's almost all beer. Brewed by the German Reinheitsgebot German purity law limiting key ingredients to malt, hops, water and yeast, Infinium tastes heavily of the former while going down as dry as bubbly.
There are subtle hints of peach on the nose before sipping and the carbonation feels more like a slow champagne popping than a beery fizz. It's also malty sweet and would pair well with the apple cider, lime juice or pumpkin bitters the brewery suggests for cocktails.
If you're considering making it a straight swap for your standard New Year's bubbly, however, be cautious. At $20 per 750mL Champagne-style bottle, it's twice as much as a decent bottle of prosecco and not nearly sweet enough or light enough (it pours a light caramel color bordering on brown) to warrant the flutes you'll be pouring it in. For beer lovers and brave souls, it's a no-brainer. For the average bubblehead, however, it may be a bit too beery for its own good.
