I've been able to burn Fireside Ultras most of the winter because the HD I go to has over 150 sitting on their deck. I know they have other shipments that are suppose to come in. But the probably cancelled the orders. Any way. Every ad that I've seen for Firesides shows that they are made from 100% hardwood.. I have a very small storage area I can keep pellets in. So about once a month I will pick some up. After I unloaded my truck I opened a bag because my stove was getting low.. So I opened it to my surprise. The pellets are yellow like pine. I filled my bucket and went into the house and scooped some out of the hopper and put a hand full on top. There is a big difference in color. Don't know if they are bagging what they can get or what.
