BC S103
I used the BC S103 wine yeast for several red's and a white ferment, and I believe it is producing a very nice product. I am finding no H2S production, like I have with other yeast options. The fermentation goes very smooth, and I am looking forward to evaluating the final wine sensory aspects.
