I started the starter on Thursday, now it's Saturday and o am brewing. Do I shake it up and Chuck the whole thing on there or do I try and decant of some of the liquid first? Or is this one of those Chevy/Ford PC/Mac kind of things?

Pitch it all. There is a lot of yeast suspended in there. If you were going to decant you would want to settle the yeast out for a few days in the refrigerator. Hope that helps!

Thanks. I've seen stuff about decanting it but didn't catch that part about letting it chill and settle out in that case.
 
I've had this inner debate my last few brews. I was afraid of underpitching so I would chuck the whole thing in there. After pondering I realized around 10-12% of my batch was yeast starter.

For today's batch, my 1.5L starter chilled for about 36 hours. I decided to split the difference. I decanted about half the liquid and pitched the rest. I ended up with lower OG and volume than planned so it probably won't hurt if I dumped some yeast.
 
I try to use the following process (when time and memory don't fail me):

1. The night before brew day (maybe a day or so sooner, depending on when I got the starter going), move the covered starter to a fridge to chill and drop the yeast.

2. Move it to my ferm chamber the morning of brewday while I am getting my gear out.

3. Once the mash is going, I decant all but about the last 1/4-inch of starter beer (or all of it if I had chilled enough to let the yeast form a nice, compact cake)

4. Add about 200-250 ml of fresh starter wort. I can my starters ahead of time in quart and pint mason jars. I usually do 10 gallon batches and often pitch 2 different yeast (1 in each 5-gal batch). That means I make 2 starters. Each starter gets half of a pint jar of fresh starter on the morning of brew day.

the starters go back into my fermentation fridge to acclimate to whatever temp I am fermenting that particular beer and to allow the small amount of starter to "wake them back up".

Since 200ml is negligible in the grand scheme of things, I usually toss that new starter in with the yeast when I pitch.
