1.03 FG with washed yeast, multiple times!
Started washing yeast and began using the washed yeast over the last several brews. First few times seemed to work well. The last two brews have had a FG of 1.03.
Outside of the washed yeast, all other techniques are consistent with the past (i.e. mash temps with the same equipment, temp controled chest freezer, ect...)
Primary 1 month
periodic shaken yeast starter with 400ml Malta drink and 400ml water for SG of 1.03.

Now have a stir plate and will be using it the first time for tomorrow's brew.
Thanks for any ideas.
What are the recipes? What yeast?
Well, first off I've never heard of people using Malta drink for starters and don't know what its contents are in terms of types of sugars and nutrients so I can't really comment on that but that was the first thing that stood out to me. Have you always used this for starters?
Other than that I'm wondering how the initial beer with that yeast turned out? Did it properly attenuate? What kind of yeast is it? And how long had you saved the yeast and under what conditions?
OP, need to know more... mash temps? yeast strain? ferm temps? recipe? Harvesting/washing process? Pitch Rates? Aeration? It's most likely not your yeast, but something in your brewing or yeast harvesting process that is causing the stalled fermentation.
