save 1/2 pack dry yeast?

[MedBrewer]

Am I risking contamination by using half a pack of yeast (safeale 05) for a one gallon recipe and saving the other half in the fridge for my next 1 gal brew?

Never considered that before! I always do this and never gave it a second thought. I suppose you'd want to seal it up good and tight if it's going to be a while.

Contamination of your yeast or of your batch? In both cases I vote no - you will probably be fine. Just tear a small hole in the pack and put it in a new ziplock after.

If it's gonna be used relatively soon, then, yeah, should be fine if you practice good sanitation .... I usually just use the whole pack in a gallon, dry yeast is cheap.

Should be ok. Just fold the edge over and tape it.

Thanks for all the quick responses! I will save other half of pack folded over and taped shut inside a ziploc till I brew next gallon within a week

Do it all the time, sometimes holding the half pack for a month before use and never had an issue. Brew on, don't stress about it.
