Haha.. Yeah, that would be quite a lot to swallow! IMO reducing makes it much easier to get down, but you have to remember that the more you reduce, the stronger the taste gets. If you have that much liquid left, yeah there's a lot to swallow, but the taste isn't as bad.. However, drinking and drinking that much liquid can't be easy.
Just leave the brews in a pot on the stove at a low simmer until you're left with an amount of liquid that suits you.
