We use leftover Christmas trees from the holidays. We rent a chipper after separating species, then steam distill the chips in our 55 gallons drums. We use Grand Fir, Douglas Fir, Noble, Alpine and Ponderosa Pine.
As with all our soaps, we use the same great recipe that is long lasting, great for the skin, and very moisturizing. Our soaps are all small batch, so each batch is slightly unique unto itself.
