Reddit mentions of Dilmah Tea, 100% Pure Ceylon Tea, Loose Leaf, 4.41-Ounce Boxes (Pack of 6)

search for an "ice tea maker" on amazon from mr.coffee, hamilton beach, west bend. they all make models that brew 2L-3L properly every time. i still use an old mr.coffee TM3 model which is cheap and works great even after 1,000 brew cycles. trust me, i know what i'm talking about - i drink 2-3L each DAY. I use standard dirt cheap 8-12cup coffee filters when brewing loose tea in the TM3. once you find the model you like, double check pricing at walmart.com as they often sell kitchen gadgets at a deeper discount with cheap ground shipping.

be mindful of your sweetener since you drink so much. years ago i switch from sugar to cheap kirkland(costco) sucralose(splenda) which helps keep weight off and my teeth from rotting, but if you don't want artificial, then your only choice is Stevia which may take a while to get used to it's leafy aftertaste. I suggest cheaper bulk Stevioside 90% powder, not any commercial brand. i flavor my tea with an extra ounce per cup of milk, pink grapefruit juice, cranberry juice, or peach nectar, whenever I find them on sale, so no need to buy exotic tea blends, as any robust black or green will do.

one additional suggestion is to be mindful of your tap water quality. i use a counter top canister filter for under $30 that will last for years, and totally removes the chloramines(ammonia taste) from my NYC tap water.

I recommend brewing with broken piece loose teas, not full leaves, since broken pieces will agitate better in a 8-12 cup filter and give you a deeper richer full tea brew flavor and color. my favorite high volume best value black tea brewing would be Dilmah http://www.amazon.com/Dilmah-Ceylon-Loose-4-41-Ounce-Boxes/dp/B00112GBO0 or for a wide flavor blend try Taylors; http://www.amazon.com/Taylors-Harrogate-Yorkshire-8-8-Ounce-Packages/dp/B001E5DXY0 and you only need 1 gram per 8oz cup while measuring i recommend using a cheap $10 digital postage scale since you need to measure by weight not volume(spoons). if you don't want to deal with filters and weighing, use http://www.amazon.com/PG-Tips-160-Bags-17-6/dp/B000YB7XQ4 at a ratio of 1 bag per pint, so for a gallon or 2L-3L i use 8 bags - these are large cotton bags that leave the tea room to agitate - unlike most commercial paper tea bags that can only seep.

in my daily ritual the way my TM3 works is the pitcher is double the capacity of the brew water hopper (presumably so you can add ice cubes to the pitcher). so I double cycle brew the same leaves till my 3L pitcher is nearly full, then I transfer it to any 2L-3L size liquid serving or storage container and add my sweetener there. I use gallon plastic screw cap jugs, but you can go with glass by using http://www.amazon.com/gp/product/B0000DE9B5 to keep the brewed tea liquid from new air exposure. by using air sealed containers you can stock up to a weeks worth of tea in your fridge before a fermentation taste is noticeable on pre-sweetened with splenda or stevia - with sugar the fermentation taste is noticeable by the forth day.

i only brew tea to drink it later once cold, so my opinion may not be relevant for most posting here. i used to drink http://www.amazon.com/gp/product/B00112GBO0 but the price went up 50% this past year, so i started looking around for a similar tasting assam&ceylon, similar potency (1g:8oz) alternative. i found this at my local indian grocery http://www.amazon.com/Tetley-Loose-Leaf-Tea-31-75-Ounce/dp/B001VIIXXQ to be a worthy substitute which is slightly less leafy and also keeps longer (does not ferment) in my fridge enabling me to make larger batches less frequently. the typical Adagio sipper posting here won't be impressed, but if you consume 100g of tea per week (6 gallons), you are looking for the best neutral pH robust malt:leaf tea flavor money can buy, and that blue box Tetley loose suits my needs perfectly - the Indians shopping at the Patel brothers grocery chain can't seem to get enough of the stuff, and they come from a former British colony that grows a quarter of the World's tea production. an additional bonus with that Tetley is it's dust free fanning size baked spheres of leaf - agitate well in my 82°C/180°F Mr.Coffee Tea Maker, thus helping liberate all it's best tea notes. if you buy either Dilmah or Tetley, http://i.imgur.com/xHMfop8.jpg make sure you transfer it to another sealed container once you open their foil pack, as the box they ship in does poorly for storage and reuse. I have not found any Chinese or Japanese blacks to like, as I generally find them to be bland, leafy and over priced just because they are whole or broken leaf - when compared to dark malty fanning or orange pekoe size Indian blacks. unlike most posting here, i don't like leafy tasting tea, which is why i only sample whites, greens, and won't use stevia as a sweetener. the only chinese teas i regularly drink are dark oolong.
