I'm in the middle of making my first brew. It is a PM Whisky Stout from a Brewer's Best Kit. This is a new Recipe from them, therefore the ingredients are fresh. However, the local brew store told me to buy the ingredients fresh from them b/c the kits have old products. This makes since to me. However, I am no expert and probably can't taste the difference b/t the 2. So my question is, unless I'm entering my beers in some kind of contest, does it really matter if I buy the kits or buy the ingredients fresh out of the stores? Also same question about PM vs All grain brewing?
