I am currently making some wine from the concentrate that homewinery(www.homewinery.com/) sells and I recently heard of Walker's(http://www.walkersfruitbasket.com/) and thought I might give them a try as well. One sells concentrate and the other sells "Hot packs" of what I am guessing is pure juice? I hear great things about both of these places and was curious as to what the advantages and disadvantages are between these two options. What are your personal opinions and experiences with these two?
