Company email (January 2012)
"Only rarely do we use a clarifier called biofine, which is an isinglass animal product. Everything else we make is 100% barley, water, yeast and hops. Currently we had clarity issues with a lager strain, so our Steam Train and Imperial Pilsner were dosed with biofine. You can always email the brewer for the most accurate data on a batch."
