Ever since I began using yeast starters, I've made them in Erlenmeyer flasks. However, it doesn't seem to matter how or when I try to add the extract (usually using a funnel), it always clumps up in the "delivery device" and causes problems.

I guess what I'm trying to ask is...does anybody have a good way to add DME to an Erlenmeyer flask with heating water, without it clumping, etc?!

Thanks.

Hm, I always weigh the DME on a piece of aluminum foil then curl it into a funnel.

I add it ahead of time (cold, no sticking) and keep the flash moving until it dissolves.

I add it cold and then shake the crap out of the flask until it dissolves, then put the flame to it. No clumps that way.

+1 on adding DME when cold, then shaking like crazy. Works very well for me.

I add DME before heating the water too. If you have a stir-plate, use it to stir-up the solution prior to boiling. Stir bars can be boiled.

Thanks for all the replies! I'll try that on my next batch. I've also read from a few different sources that people also add hops to a starter for anti-septic qualities. Anybody think that is really necessary?...

Are they ceramic magnets? I'd assume they are for cost savings. If so, then I'd be careful about heating and cooling them repeatedly since it will de-magnetize them.

Teflon-coated magnets.
