I am looking to make a 1L starter, and have a 3L Erlenmeyer Flask that will be on a stir plate. The 1L mark is pretty low on this relative to total height -- is there going to be any issues with how much surface area there is in terms of it drying out too much over a few days?
Will it make it difficult to decant after cold crashing?
Don't want to have to get a smaller size flask if not needed -- I would think this ratio would work, but if anybody else has similar experience or thoughts on the matter - would love to hear them. Thanks!
It should be fine as far as evaporation. If you have some way to hold it at an angle while cold crashing, that would make decanting easier. Or, you could grow a bigger starter, then keep the extra yeast in a sterilized mason jar for your next batch.
It's not part of your question, but what is the volume you will be fermenting and what is the planned gravity? Just curious why you're making a 1 liter starter and not something larger. Low cell count in your starter yeast?
I use a 5L flask because that's the only one I have. No issues at all in doing a 1.5L starter and then stepping up after decanting. 5L is really big, have to adjust the shelves in the fridge if I want to decant.
