They are made by the same mfgr who also make beer yeast. this is a smack pac I believe.
I have not used it as I feel the LALVIN and Red Star work well. and 1/10 the cost

Liquid wine yeast, I have not used the liquid for wine yet but use it for beer and it does a great job. With beer it is imperative to get it going very fast as beer is much more susceptible to infections due to the grains and that such so getting some abv under its belt fast is really needed.
