put 500g of dry malt extract in 5L of water to get 1040 wort, boil for 20 mins, cool to 20-25C and put into a suitable vessel (e.g. 5/10L demijohn), put an airlock on and let it ferment, if you don't want the starter volume diluting the beer then wait for the yeast to settle out and pour off some of the liquid,might be waiting a while with 3944 though as it doesn't flocc well. If you swirl the starter up every so often or make a stirplate you can reduce the volume a bit as the yeast will grow better
How big a batch have you got on to need a 5L starter?
i have a 46 liter batch and using a stir plate, but i do not have 5lt flask they are expensive...
Skip the stirplate this time.i have a 46 liter batch and using a stir plate, but i do not have 5lt flask they are expensive...
Thanks wolfy I went to keg king today and got one of those flask she's a ripper... Got a heap of other stuff while thereGlass (especially borosilicate glass) is easy to use and work with because it can be heat sterilized/sanitized, but if you take care with sanitation, there is no reason you can't use something cheaper and more readily available, it just needs to hold the volume of wort, have a flat bottom and have a cover over it.
So the jar should work fine*, as would a demijohn or even a cheap-square-plastic-container or even a new/clean laundry-bucket ($0.87 from Bunnings today).
*It's hard to tell from the picture, but the jar might have a curved base, which makes positioning the stir-bar difficult, but with (lots of) trial-and-error, you should be able to get it to sit right - it's the trade off for using a cheaper jar and not a flat-bottom flask (KegKing sell 5L flasks for ~$30 which is very cheap compared to elsewhere).
