I am getting good flavor with 1/3 the amount of the loose rooibos that I found (fresher tea, I think, so more flavor) in the Hamilton Beach iced tea maker (both the tea and the small appliance were bought off eBay - but Wal*Mart is supposed to have the tea maker or you can buy an inexpensive Mr. Coffee or Mr. Tea and just pour the results into a pitcher to chill, I'm sure - it's what I'm doing in the resort mini-kitchen).
I also have a Black & Decker coffee maker that makes up to 15 oz. of tea, coffee, or hot water into a travel mug (which comes with it and coincidentally holds 15 oz.) - it works very well & has a built in filter, no paper filters needed. I have been steeping the tea in the hot water, instead of using it in the filter. Since I didn't bring it with us on vacation - I'll have to try it once I get home.
I have an espresso machine, a 12 cup coffee maker, a 4 cup Mr. Coffee, the Black & Decker coffee maker, the Hamilton Beach iced tea maker, and a French Press (never used) - it may go to a fund raising garage sale the next time VorGuy's students set one up...and I almost forgot the clear glass tea pot with glass infuser (intended for blooming teas) that does NOT work with loose tea - the infuser slots are too large & I have to filter the tea.
Um - I may have been trying too hard to find the "perfect" tea and coffee makers...may need to post getting rid of a couple of these to the decluttering thread! I can't get rid of the 4 & 12 cup coffee makers as long as VorGuy is teaching school, as they get taken on field trips to make large batches of tea or hot chocolate (or even coffee - depending on what is wanted by various students & chaperoning parents).
