So, I understand the process of washing yeast, though I've never done it. It seems to me that buying brand new yeast is just not expesive enough to force me into washing old yeast.
That said, I've heard of a lot of people dumping new wort on old yeast. I was hoping to hear from them and find out if they've had any problems. I've put a small amount of new wort on an old yeast cake, swirlled it, and pitched into a clean carboy before and never had a problem. Is this the method most people use? I bring this up because I was chatting with the LHBS guy and he warned me that I should not reuse the yeast from an IPA for a stout as I would pick up to much hop flavor...Not sure I buy that. Any experience input on the subject would be great.
