The cans that these yeasts come in kinda bug me. Maybe its user error, but if I let the yeast warm up to room temp before pitching, the can explodes and makes a mess, and if I open it cold, that means I pitch cold and risk temp shocking the yeast. And the English ale yeast sticks to the bottom of the can and is a pain to get out, because if I vigorously shake the can to get all the yeast in suspension, it explodes when I open it.
Sorry, don't mean for my first post here to be complaining, I have used their pub yeast strain, tartan (Scottish ale) strain and the rustic (3726) strain, and aside from the packaging, have no complaints. The tartan in particular was awesome in a RIS.
