You can go to any hardware store (Home Depot, Walmart, etc) and in the paint section are straining bags well suited for this purpose.

I usually use my wife's old stockings.

I go an buy cheap tea take the bags apart dump the tea in my worm bins refill the bags with aged vermicpost one bag makes
about 2-1/2 gallons. well that's how big my watering can is
I do not boil the water or use a fish pump to mix the vermicpost I just drop it in the can an let the sun do the
work add a little stirring with a stick and about 5 min i have
vermicpost tea. I'm still working on getting the right amount
of vermicpost in the tea bag ( Oh Ya the right amount ??? ).
But for now everything seems to be working.

I make compost tea by putting a handful or more of vermicompost in a bucket of water. I leave it for at least 24 hours and stir it several times. The compost doesnt have to be in a bag, does it?

Nope, the compost does not have to be in a bag to make tea. I've made "manure" tea for years the way you make compost tea and have never put the manure in bags.

I generally make compost tea by rinsing & scrubbing off my compost fork and compost sifter (and hands :) in a bucket of clear water. Then I strain the no-longer-clear water into my pressure sprayer, and dump the stuff in the strainer back into the compost.

I'm with wormfarmer, JustMee and Evelyn; I make my teas without a bag, and the "used" castings, which have lost little of their value, are put back into the bin and ultimately used in the garden or planting bed.

I am all about keeping things simple!

If the worm castings have lost little of their value, is there much value in compost tea? I've never tried it, so I'm just the guy with the dumb look on his face...

Is the liquid at the bottom of a layered worm farm considered compost tea? Can it be simply diluted then spray on plants? Or must it be brewed in some way?

It's not compost tea, it's leachate, and it may have pathogens, so don't spray it on your plants. However, I dilute it with water and water my plants with it, and have never had a problem doing that. In fact, the plants seem to like it.
