The Perlick 425SS boxes say:
FAUCET BEER, CHROME FIN.
W/SS SHAFT & SPOUT
It's been like that for at least the last few years. The only metal parts that might actually have a chrome finish would be the bonnet and the handle locknut. All the metal parts that contact the beer are stainless steel.
On tap:Witbier, American Stout, Imperial Stout, Root Beer
Bottled:"Massacreation" Chinook Barleywine, Belgian Golden Strong Ale, English IPA, Cabernet Sauvignon
