I didn't know Pizza Libretto had its own house beers. A bit of Googling indicates that it's likely brewed by Gananoque Brewing Company, which I haven't heard of before.The new house beer, Libretto Forte IPA, is a full-flavoured, thirst-quenching rejoinder to this uncompromising pie.
Anyone tried their beers? Shamefully, I've never been to Libretto, but I'm now that much more interested!
