About $150 a year for a daily tea drinker — that’s the difference between bagged grocery-store tea and loose-leaf that you steep multiple times. A box of 20 grocery-store tea bags runs $4, or $0.20 per cup. A 4-ounce bag of decent loose-leaf is $12-18 and yields about 50 cups at the standard 2 grams per steep — that’s $0.24-$0.36 per cup, which looks worse. But good loose tea steeps 2-3 times without losing much. Run that math and you’re at $0.10 per cup with loose-leaf, drinking better tea for less than half the cost of bagged.

This isn’t an article about switching all your tea to loose-leaf. It’s about knowing which teas reward the format and which don’t, and understanding that the per-cup math only flips when you’re steeping multiple times. If you drink tea once a week, none of this matters. If you drink it daily, it does.

Which teas are worth buying loose

Green teas, oolongs, white teas, and anything with a Chinese or Japanese name you have to look up — gyokuro, longjing, tieguanyin, pu-erh. These are the ones that steep 2-3 times and actually get more interesting on the second steep. A good sencha or dragonwell will give you a solid first cup, a mellower and sometimes sweeter second, and a lighter third if you’re not in a hurry. You’re paying $14-18 for a 4-ounce bag, getting 50 cups across 20-25 sessions, and the per-session cost is $0.56-$0.72 — cheaper than a bagged equivalent that you’d throw out after one steep.

Oolongs are the most dramatic example. A decent tieguanyin or dong ding will steep five times if you let it. I’m not counting past three in the math here because most people won’t bother on a weekday morning, but if you do, you’re well under $0.10 per cup.

Black teas are a harder sell. Most breakfast blends and Assams don’t improve much on a second steep — they just get thinner. You can do it, but you’re not gaining the same quality-per-dollar return. If you’re drinking a straight Irish breakfast every morning, bagged is fine. If you’re drinking a Darjeeling first-flush or a Yunnan gold, loose makes sense, but you’re doing it for the flavor, not the savings.

The equipment

You need a mesh basket or infuser. That’s it. A decent stainless steel basket that sits in your mug runs $12-15 and lasts years. Don’t buy a teapot with a built-in infuser unless you already want a teapot. Don’t buy one of those novelty infusers shaped like a manatee. Just get a simple basket with a fine mesh and a handle.

Some people will tell you you need a gaiwan or a kyusu. You don’t. Those are nice if you’re sitting down for a deliberate tea session, but they’re not required to make the math work. A basket in a mug is enough.

The other thing you don’t need: a scale. Two grams of tea is about a teaspoon, maybe a little more depending on the leaf size. Eyeballing it is fine. You’ll figure out your preference after a few tries.

What to spend

The floor for loose-leaf that’s actually worth re-steeping is around $14-16 for a 4-ounce bag. Below that, you’re mostly buying dust and fannings that won’t hold up to a second steep. Above $20, you’re paying for rarity or sourcing story, which is fine if that matters to you, but it’s not where the value math lives.

I’m assuming you’re buying from an online tea retailer or a local shop with decent turnover, not the bulk bins at the grocery store. Those bins have usually been sitting there for months and the tea tastes like it. If you’re in a city with a Chinese or Japanese grocery, the tea selection there is often better and cheaper than the specialty shops, but you need to know what you’re looking at.

One more thing: sample sizes. Most online tea shops sell 1-ounce samples for $4-6. If you’re new to loose-leaf, start there. A single ounce is 12-15 servings if you’re steeping twice, enough to figure out if you like it before committing to a larger bag.

A note on the math

I’m assuming two steeps per session and a 2-gram dose, which is standard for most greens and oolongs. If you’re only steeping once, loose-leaf is not cheaper — it’s roughly the same price as bagged, and you’re doing it purely for quality. If you’re steeping three or more times, the math gets even better, but I’m not counting on that because most people won’t.

The $0.20-per-bag figure for grocery-store tea is based on a $4 box of 20 bags, which is typical for Bigelow, Twinings, or the store brand. If you’re buying Tazo or a premium bagged tea at $6-7 for 20 bags, you’re already at $0.30-$0.35 per cup, and loose-leaf is cheaper even on a single steep.

The per-cup cost for loose-leaf assumes you’re buying in the $14-18 range for a 4-ounce bag. If you’re buying $8 tea, it’s probably not good enough to re-steep. If you’re buying $30 tea, you’re not reading this for the savings.

The takeaway

This isn’t a cost article so much as a quality article that happens to also save money — but only if you’re drinking the right teas and actually using them twice. If you’re a daily tea drinker and you’ve been buying bagged green or oolong, switching to loose is cheaper and better. If you’re drinking bagged black tea once in a while, don’t bother.
