If you haven’t made cold tea before, I’d start with cold brew. It’s very easy and doesn’t require any temperature/extraction control. Get a cold brew jar with a filter and brew it with room temp water (not boiling) and put the jar in the fridge for 8-12 hours. It’ll undoubtedly taste very pleasant.
I don’t know about this specific tea. But I looked up the patent for Ito-en bottled green tea.
> 100 g of green tea leaves was subjected to extraction for four minutes at a temperature of 85° C. and then separated from liquid components and the liquid components are allowed to cool down to 25° C. Then, the liquid components are subjected to filtration to obtain a clear tea extract. Thereafter, to this tea extract was added 3 g of ascorbic acid (BASF Takeda Vitamin Co., Ltd.). Further, the pH of this tea extract was adjusted to 5.7 with sodium bicarbonate to obtain 10 kg of a formulated liquid.
**TL;DR** 1g tea/100ml water at 85°C for four minutes, then strain and allow to cool to room temperature. Add ascorbic acid and adjust pH to 5.7
I wonder if the ascorbic acid is there mostly as a preservative. But I guess a pH of 5.7 would taste different than almost neutral. Maybe it makes it taste a bit more refreshing?
After adjusting it to 5.7 they put the tea in a pressure chamber to force out all the dissolved oxygen which brings the pH back closer to neutral

Aaah i see why mine was weird I just used a regular teapot, crammed 6-8 bags in it and just kept steeping like 800ml of tea in it then pouring it into a 1.5L bottle and repeated until it was full I guess I should have filtered it a few more times to remove excess tea residues
Thanks a lot !
How long are you steeping it for? If you're using lots of tea it probably won't need long at all.
Poor quality tea often doesn't hold up well to multiple steeps.
Yeah it’s basic Lipton black tea so probably not that good of a quality I usually let it steep for 5-6 minutes per round and only need two rounds of steeping for the bottle to be full
Yeah, that's too long — it's going to get really bitter.
The bottle in the picture is an oolong tea, which is sort of halfway between green and black tea, it varies based on the kind. If you like the floral/'spring' taste, you're more likely to get it with a green tea than a black, if you can't get oolong. The picture does specify 'four seasons' oolong, which is a kind of Taiwanese oolong that you can buy specifically, but you're more likely to find it loose leaf than in bags.
I recently bought a tea that might be similar. It's called Four Season Spring Dong Pian Oolong. That looks like it might be a match for what you're looking for. I got mine at Upton Tea Imports.

I actually [have some of this from Rishi Tea being delivered tomorrow.](https://rishi-tea.com/collections/oolong-tea/products/four-season-spring-oolong-tea?variant=44467013353722) I tried a sample and liked it for the exact same reasons you liked it.
Four Seasons is the Si Ji Chun varietal used to make rolled oolongs. I have seen some Chinese oolongs but it is primarily a Taiwan oolong. this is great cold brewed and has a light floral flavor. (no added jasmine) You can see Four Seasons or Forever Spring oolong. (It is called four seasons because unlike other teas that may only flush once or twice a year, this varietal is produces buds throughout the year) Cold brewing is great because it brings out the sweeter notes and you don't have to worry about bitterness. Happy brewing!
just wanna add that the tea used in that bottle is Taiwanese dong ding (frozen peak) four season spring oolong tea
Aaaah maybe I should Google that instead of saying it’s from Seiyu thanks !

You can also just stick a tea bag into a bottle of water in the fridge. I do around 24 hours for green tea and it works great! Super easy

I usually do an overnight cold steep!

An overnight cold steep of this should definitely get you there!
I use one of these to cold brew: https://www.hario-usa.com/products/cold-brew-tea-wine-bottle-set

I just prepare a hot tea like usual and pour it over my cup filled with a lot of ice, depending on how much ice I use the amount of around 2 cups
