Its all good! Love that yeast! Like he said just pour into a glass slowly and try to leave about 1/4 of an inch of beer in the bottom of the bottle. Dont worry though if you dont get the hang of pouring for a while the yeast will not hurt you
Or pour it all and drink those wonderful yeast that made such a delicious drink for you to enjoy! Perhaps I am a bit sentimental, but I'd prefer the yeast find their final resting place in my stomach than in my septic tank!
I try to leave behind the last 1/4 inch or so when I pour, but I guess my palate isn't all that advanced since I notice very little flavor difference if I do pour some of the yeast into my glass. Come to think of it, I should go pour myself a homebrew right now!
