There have always remained a few local or regional breweries that clung on in the face of the market take-over by the big beer companies. On example is Perkas Ale, which I sampled in Cusco.
There have also been some new regional breweries that have managed to get started and hang on. I've heard, for example, of Cerveza Andes in Huaraz and Cerveza Iquitena from Iquitos.
And there is, of course, the case of Ayacucho's Añaños family, who have expanded their nationwide soft drink empire into beer production with Tres Cruces beer.
However, with sole exception of the pioneering Cerveceria de Tomas, there seemed to be a dearth of craft beers and craft beer pubs in Lima itself. That, fortunately, is changing.
Last year I became aware of Cerverias Aldon's beers from Pachacamac, and in the past year it appears that at least three craft breweries have opened in Lima, and that at least one has a tap room.
