Default slow fermentation

I have been homebrewing for the past few months and have had a constant problem with slow starts using liquid yeast (typically over 48 hours) The last batch started late and is is fermenting extremely weak even though I used a yeast energizer. I believe I aerate enough by stirring the wort vigorously and shaking the carboy after the wort is added. I don't ever have problems with dry yeast.
Any suggestions....help!

Aeration is the key in my book. I use O2 and inject it into the wort. Shaking and stiring just don't cut it. The other piece is volume of yeast needed. Those homebrew packs don't come close to the volume of yeast commercial brewers use. Repitch from patch to batch is one way and is what I do. I go for a number of generations without any problem.

Slow fermentations can make you anxious can't they?

Are you using a starter? I found that pitching while the yeast is still active really cut down my lag time and adding a little that little bit of additional wort didn't affect the flavor too much.

Indeed. I decided not too long ago to produce a last minute doppelbock, and didn't make a starter. My danged lager yeast took 6 days to start. Talk about being anxious.

I don't mean to sound ignorant but what is a sterter?

Take some DME, reconstitute with some water, boil to sterilize (essentially making wort), pitch your yeast in it, put an airlock on your container, and let the yeast start fermenting. It decreases lag time and increases number of pitchable yeast cells.

48 hours is best if you can plan that far ahead.

i've had better success with a large starter than just pouring the vial or smack pack in. but reusing the entire yeast cake gets you rocking almost as you're racking the wort atop it!!!

Thanks
This is the first time I have used this site. It has thrown some light on a long term problem I have been having, and fast.

I've given starters only a few hours prior to pitching and I see a big difference compared to not using a starter at all. You should give it more than that but I guess every little bit of a head start helps.
