It's not explicitly listed but if you hover over the main kit image you'll see the yeast options on the box sticker. So far it's been what I've gotten!
I'm in north-central CT. I planted two cascade and two centennial rhizomes but unfortunately only one of each sprouted. The cascade is doing very well, although I'm worried that it didn't make it though the frost on Tuesday (I did cover it). The Centennial is very short but seems to be healthy...
