About This Black Tea
This Taiwan Ruby 18 loose-leaf black tea produces a gentle, aromatic cup defined by tangerine sweetness, faint cinnamon, and a clean mint finish. The long, unbroken whole leaves rehydrate and open visibly in the cup, and reviewers confirm the brew stays smooth and non-astringent regardless of steep time. It works equally well hot, iced, or cold-brewed overnight. Those seeking a bold, full-bodied black tea may find the flavor needs coaxing — this is a subtle, refined tea rather than a powerful one. Best suited to beginners wary of bitterness, fans of delicate flavor profiles, and gift-givers who want a presentable whole-leaf tea.
Is Clouty Space Taiwan Black Tea Ruby Right for You?
What does Ruby black tea taste like?
Clouty Space Ruby 18 has a delicate, smooth flavor that's noticeably different from typical bold black teas. Reviewers describe subtle notes of tangerine, a hint of cinnamon, and a light minty aroma. The flavor hits you upfront rather than lingering in the background, and it's remarkably smooth — not bitter at all, even if you accidentally overbrew it. Several customers mention it tastes great plain without any sweetener needed.
What is Ruby tea good for?
Based on what customers actually use it for, this Ruby 18 is great for a relaxing afternoon tea ritual — multiple reviewers specifically mention the calming, meditative experience of watching the high-quality whole leaves unfurl as they steep. It's also popular as a gift thanks to its premium packaging, and several people brew it as a daily tea since it's smooth enough to drink plain. It also works surprisingly well as an iced tea or cold brew overnight.
What makes Taiwan Ruby 18 different from regular black tea?
Ruby 18 (also called Red Jade) is a specific tea cultivar developed in Taiwan by crossing a wild Taiwanese tea plant with an Assam variety. It produces a flavor profile that's distinctly different from Indian or Chinese black teas — lighter, more aromatic, with natural notes of tangerine, cinnamon, and mint that you won't find in a standard English Breakfast or Assam. Reviewers of this Clouty Space version confirm that the flavor description on the packaging accurately matches what's in the cup, which is a good sign of authentic Ruby 18.
Is this tea bitter?
No — this is one of its strongest qualities. Four separate reviewers specifically mention that this Ruby 18 is smooth and not bitter, even when brewed strong. If you've been turned off by bitter black teas in the past, this is a completely different experience. The flavor is mellow and aromatic, making it easy to drink plain without milk or sugar.
Do you need to add milk or sugar to this tea?
Not at all. Reviewers specifically note this tea is delicious plain — the natural smoothness and subtle sweetness mean it doesn't need anything added. In fact, adding milk would likely mask the delicate tangerine and cinnamon notes that make Ruby 18 special. If you normally load your tea up with sweetener because of bitterness, you might be surprised at how enjoyable this one is straight.
What is the best way to brew this Ruby 18 black tea?
Ruby 18 is a forgiving tea to brew. Use water around 200–210°F (just off boiling) and steep for 3–5 minutes. The beauty of this particular tea is that even if you go a bit long, reviewers say it doesn't turn bitter. The loose leaves are long and unbroken, so give them plenty of room to expand — a teapot or large infuser works better than a small tea ball. The tea also comes with a tea ritual guide to help you get the most out of the experience.

Does this Ruby 18 tea make a good gift?
Yes — this is one of the most consistently praised aspects of the product. Five separate reviewers specifically mention the packaging being presentable and gift-worthy. The whole presentation feels premium, from the packaging to the high-quality whole leaves inside. It also comes with a tea ritual guide, which adds to the gift experience. If you're looking for a tea gift that looks as good as it tastes, this is a strong choice.
Is this a good tea for beginners?
This is actually an excellent beginner tea. It's mild and smooth without being boring — you get interesting flavor notes (tangerine, cinnamon, mint) without any bitterness or harshness. It's very forgiving to brew, meaning you won't ruin it if your water is too hot or you steep a minute too long. The included tea ritual guide is a thoughtful touch for someone new to loose leaf tea. Multiple reviewers mention it as a good introduction to quality black tea for people who normally don't drink tea.
How does this compare to other Ruby 18 teas?
Reviewers highlight this Clouty Space version for its impressive leaf quality — long, unbroken whole leaves that look premium. The packaging is a cut above most competitors, making it more gift-worthy. The flavor is on the more delicate side of the Ruby 18 spectrum, which some see as smooth and refined while one reviewer felt it could be a bit mild. If you prefer a bolder tea experience, you might want to use more leaves per cup. Overall, reviewers indicate the flavor description on the packaging accurately matches the actual taste, which speaks to its authenticity.
How to make black tea more tasty?
Honestly, with this Ruby 18 the best tip is to drink it plain first. Multiple reviewers mention it's delicious without sweetener, and the subtle tangerine and cinnamon notes are best appreciated on their own. If you find the flavor too mild (one reviewer did mention it can be subtle), try increasing the amount of leaves rather than steeping longer, or try a gongfu-style brew with more leaves and shorter steeps. This concentrates the flavor without any bitterness.
What is the flavor profile like compared to the description?
This is actually a strong point for this tea. Two reviewers specifically mention that the flavor description on the packaging accurately matches what you taste in the cup — tangerine, subtle cinnamon, and a light minty aroma. That's not always the case with specialty teas, so it's a good sign of quality and honest marketing. The flavor is delicate rather than bold, so set your expectations accordingly.
How many cups can you get from one bag of Clouty Space Ruby 18?
This is worth knowing upfront: one reviewer noted the quantity in the bag is small relative to the bag size. With high-quality whole leaf tea like this, you typically use 3–5 grams per cup, and the good news is you can re-steep the leaves 2–3 times. So while the initial bag might look small, you'll get more cups than you'd expect if you re-steep. That said, a heavy tea drinker could go through the bag in just a few days.

How to brew black tea for iced tea?
This Ruby 18 works really well as iced tea or cold brew. For cold brew, add the loose leaves to cold water and let it steep overnight in the fridge — you'll get a smooth, naturally sweet flavor. For quick iced tea, brew it hot at double strength (use twice the leaves), then pour over ice. Either way, the delicate tangerine and mint notes come through beautifully cold. Reviewers confirm it's great both hot and iced, and it's smooth enough that you won't need sweetener.
Can you cold brew this Ruby 18 tea?
Yes, and reviewers say it works well. Just add the loose leaves to cold water and steep overnight in the fridge. Cold brewing brings out the sweeter, smoother side of the tea while reducing bitterness (not that bitterness is an issue with this one anyway). The delicate tangerine notes come through nicely when cold brewed. It's a great option for warm weather or if you prefer iced tea.
What are 5 benefits of drinking black tea?
Black tea offers several well-documented benefits: it's rich in antioxidants that support heart health, contains L-theanine that promotes calm focus, supports digestive health, provides moderate caffeine for sustained energy, and may help manage blood sugar levels. With this Ruby 18 specifically, reviewers also highlight the mental wellness benefit of the tea ritual itself — the act of brewing whole leaves and watching them unfurl is genuinely calming.
Is black tea good for you in the morning?
Absolutely. Black tea is a great morning drink — it has enough caffeine (40–70mg per cup) to wake you up gently without the crash that coffee sometimes brings. This Ruby 18 is smooth enough to drink on an empty stomach without any bitterness or stomach irritation. That said, several reviewers specifically associate this tea with afternoon relaxation rather than morning energy, so you might find it works best as a mid-day ritual.
Does Ruby black tea have caffeine?
Yes, Ruby 18 black tea contains caffeine like all true teas made from Camellia sinensis. A typical cup of black tea has around 40–70mg of caffeine, roughly half what you'd get from coffee. Ruby 18 is a fully oxidized black tea, so it falls in that standard black tea caffeine range. It's a solid choice for an afternoon pick-me-up without the jittery feeling coffee can cause.
What are common black tea mistakes?
The most common mistakes with black tea are using boiling water directly (let it cool to around 200–210°F), steeping too long, and cramming loose leaves into a tiny infuser where they can't expand. The good news with this Ruby 18 is that it's more forgiving than most — customers report it doesn't get bitter even when brewed strong. The one thing to watch for is that it has a delicate flavor profile, so if you want the full tangerine and cinnamon notes to come through, don't overwhelm it with sweetener or milk.

How to brew black tea loose leaf?
For this Ruby 18 loose leaf, use about 3–5 grams of leaves per cup. Heat water to around 200–210°F, pour over the leaves, and steep 3–5 minutes. These are beautiful whole leaves — long and unbroken — so use a roomy infuser or brew directly in a teapot where they have space to open up. Part of the experience with this tea is watching the leaves rehydrate and unfurl, which multiple reviewers mention as surprisingly enjoyable. You can re-steep the leaves 2–3 times, which helps stretch the value.
How long do you boil black tea for?
For Clouty Space Ruby 18, you don't actually want to boil the tea itself — bring your water to a boil, then let it cool just slightly before pouring over the leaves. Steep for 3–5 minutes depending on how strong you like it. One of the nice things about this tea is that reviewers note it stays smooth and mellow even with a longer steep, so you don't need to hover over it with a timer.
What happens if we drink black tea daily?
Drinking black tea daily is generally considered a healthy habit. Black tea is rich in antioxidants and polyphenols that support heart health and gut health. This Ruby 18 is particularly well-suited for a daily routine — it's smooth, not bitter, and several reviewers specifically describe it as their daily go-to tea. Just keep in mind the caffeine content if you're sensitive, and you may want to avoid adding sugar to keep it healthy.
Which is healthier, black tea or green tea?
Both are healthy in different ways. Green tea gets more press for its EGCG antioxidants, but black tea has its own set of beneficial compounds — theaflavins and thearubigins — that support cardiovascular health. The real health advantage comes from drinking tea consistently, whichever type you enjoy most. If you find green tea too grassy or bitter, a smooth black tea like this Ruby 18 that you'll actually want to drink daily is the healthier choice for you.
Is there enough caffeine in black tea to keep you awake?
Black tea like Ruby 18 has moderate caffeine — enough for a gentle alertness boost, but significantly less than coffee. Most people can enjoy a cup in the afternoon without it affecting sleep, though sensitivity varies. Reviewers of this tea specifically mention it as part of a relaxing afternoon routine, so it seems to hit that sweet spot of mild energy without overstimulation.
Is black tea more caffeine than coffee?
No — coffee typically has about twice the caffeine of black tea. A cup of coffee runs 80–100mg of caffeine, while black tea like this Ruby 18 is usually in the 40–70mg range. That makes it a nice middle ground: enough caffeine for a gentle lift during your afternoon tea break, but not so much that it'll keep you up if you have it in the late afternoon.

How to brew black tea for milk tea?
While you certainly can use this Ruby 18 for milk tea, it's honestly not the best choice for that. Ruby 18's appeal is in its delicate tangerine and cinnamon notes, which would get lost under milk. For milk tea, you'd want a stronger, maltier black tea like Assam or CTC-processed tea. If you do use this for milk tea, brew it extra strong with double the leaves to help the flavor come through.
Is black tea good for you when sick?
Black tea can be comforting when you're under the weather — the warmth soothes the throat, and it provides gentle hydration with a small caffeine boost when you're feeling sluggish. This Ruby 18 has a light minty aroma that could feel refreshing when congested. The fact that it's smooth and not bitter makes it easy to sip when your appetite or taste is off. That said, herbal teas (ginger, chamomile) are often better choices specifically for illness recovery since they're caffeine-free.
