Yeast Starters
 
Do you have to use DME for starters or could I use sugar or a substitute?

Technically sugar would work, but it's generally not advisable. When cultivating a starter, it's best to stick to feeding it something akin to that which you ultimately want it to be working on. Cultivating it with sugar can cause changes to the yeast itself and may result in poor attenuation, off flavors, etc. when compared to using DME.

Basically, don't do it :).

No. Definitely not. After two - three generations of eating simple sucrose yeast loses the ability to digest maltose. You'd basically be pitching inactive yeast.

LME

wort

Well I figured it was no. I just asked so i might get a yes.

In the 8 batches of beer that I've done (newb), I've always started with sugar and never had inactive yeast.

It is amazing what you can get away with... conversely, it is amazing what I'm reading on this forum that you can't get away with, if you're willing to look at it like that.

Cool I brewing next week and I don't want to wait for a package a DME and have to pay. What are the consequences if I do this once and what Doe you guys use to keep it in besides a flask?

I make my starters in an old glass jug and use a stopper + airlock to treat it just as I would if it were a batch of my favorite brew.

If you have a local home brew shop go pick up some DME. Grab a few pounds of extra light to keep on hand to make starters with. Using plain old sugar for a starter vs making a simple wort with DME or LME is a bad idea. You may as well make no starter. I learned this first hand. I had horrible attenuation and had to pitch more yeast to finish it off.

Ok so your not with the idea of sugar either?

I think the consensus you'll ultimately get out of this is going to be that you can, but no one will recommend that you do so. If it's your only option outside of waiting for a new shipment to come in, go for it, just be aware that it can cause some attenuation issues. And for future batches, make sure to keep some DME on hand for starters :).
