    That 1 minute technique will save a bit of time and a ton of boil off that I get with the 15 minute boil for my starters.

    Interesting... I think Palmer says boil 10 minutes, some of the books might even say longer than that. I've been boiling 12 minutes. Think of all those minutes I've wasted...

    Other lessons:
    * Unlike the picture, be sure to cover the flask while cooling.
    * Learned this last week - don't make a 2L starter in a 2L flask or you will end up with yeast exploding all over your kitchen counter :flushed:

    Heck, I leave it on for the boil so it sanitizes on its own...

    Well I made my starter this afternoon. I boiled a L of water and added 1/4lb DME and let it boil for 10 minutes. Then I poured it into a sanitized caraffe and cooled it to 75 degrees. Then I poured the room temp WL year in, covered with foil and swirled. I've been swirling a few times today. It's already going pretty strong. It foams each time I shake. I think I'll try the method of cooling it, bringing it bak to room temp while I boil my wort, skim off all but the inch of liquid, stir and pitch. Either way this should be better than what I've always done, pour the WL yeast strait into the wort.

    I haven't bothered reading the other posts but your ratio is 100 grams per liter which means 3.5 ounces per liter. My opinion of the easiest way to make one is a buy a 2000ml erlenmeyer flask, use mrmalty.com, and look into buying a stir plate.

    So I put the 1000ml & 1/4# of DME starter together yesterday. It's been going for about 32 hours. I've got a nice amount of yeast at the bottom and it's still kind of active. I'm brewing tomorrow around 10am (13.5 hours from now). I should be pitching the yeast around 12pm.

    Should I put the starter in the frige and drain most of the liquid tomorrow or should I just pitch it all when it's time and allow the next 15 hours of fermentation to occur?

    I have just let it go until the wort is chilled and pitched the whole thing with satisfactory results. Although my best results are when I pitch the intended yeast onto a smaller beer and re-pitch the yeast for a big one. In that case I rack the smaller beer into secondary while the bigger beer wort is chilling after the boil, and use the flocculated yeast at the bottom of the primary.

    I know what I just posted is a bit off track for what you are doing now, but I had to mention that this worked better for me than pitching directly or any other starter/technique I have tried.

    That sounds interesting. I think I may chill it for a few hours and drain Off the extra liquid.

    If you are only chilling for a few hours, make sure the starter 'beer' actually clears. If it doesn't, and you decant a lot of cells away with your liquid, you'll lose a lot of cells (obviously). But you may also be selecting for the most flocculent (and/or least viable/vital) cells, and potentially pitching a population that may decide not to finish the job. Maybe not a huge risk in the 'first' generation, but I'd still pitch the whole starter rather than decant a significant amount of cells.

    So I would then take it out the frige, bring to room temp, swirl and pitch I guess right?

    If it hasn't completely settled, that's what I'd do, yes. Though I'd say 'pitching temp' rather than room temp if they are different.

    I personally pitch the entire yeast starter at high krausen; pitching when the yeast is active helps the ferment to start quickly.

    Below is from the article The Secret to Healthy Yeast: Making a Starter By Jamil Zainasheff Zymurgy March/April 2007. You can download the article from here: http://www.homebrewersassociation.org/pages/zymurgy/free-downloads

    “I like to pitch starters while they're still very active and as soon as the bulk of reproduction is finished, usually within 12 to 18 hours. This is really convenient, because I can make a starter the morning of the brew day or the night before and it is ready to go by the time the batch of wort is ready.

    Of course, if you have a large starter volume in relation to your batch of beer or a starter that was continuously aerated, then you probably don’t want to pitch the entire starter into your wort. Adding a large starter or a heavily oxidized starter to your wort can alter the flavor of the finished beer.”

    Cheers!
