Once dry yeast is open it cant be stored. I dont like throwing away half a pack of dry yeast when doing small experimental batches. debating about making a starter with extra yeast and saving for next experiemental batch and save money.

Should i make the starter at a higher gravity? any downside to my thinking?
 
I've done starters from US 05, kept them in the fridge for a couple months with no problems... got one fermenting right now actually.
 
You can make a starter but keep the gravity between 1.030-1.040. Remember you want to grow yeast without stressing them out in a high alcohol environment. When you are done just discard all the "beer" and pour the yeast slurry into one or several sanitized containers. I use old White Labs vials.
