Buy the Craft A Brew kombucha kit if what you want is a good one-gallon jar and a live culture, and you already have black tea and plain sugar in the cupboard. The catch is that two different kits are sold under almost the same name: the maker's own Kombucha Kit publishes organic tea and cane sugar in the box, and the Basic Starter Kit — the one that resolves to a buyable listing — publishes only the culture, the jar, the cloth cover and the guide. Neither publishes the volume of starter liquid, and neither includes pH strips or bottles.
What this review is
Nobody here has brewed on this kit. What this page does instead is what every review on this site does: read everything the maker and the listing publish, hold the numbers against the kits already documented here, and be explicit about which claims belong to the seller.
That method matters more than usual with this particular product, because the thing most likely to go wrong with a Craft A Brew order is not quality. It is buying the wrong one of two near-identically named kits.
There are two kits, and the difference is tea and sugar
Craft A Brew's own shop lists a Kombucha Kit whose published contents are a 1-gallon glass brewing jar, a live SCOBY with starter liquid, organic tea, cane sugar, a brewing cloth cover with rubber band, and a step-by-step guide. It also offers a Deluxe version that adds bottling equipment and a funnel, and a variant where you claim the SCOBY later rather than having it shipped with the box.
The listing that resolves to a live, buyable product for this site is a different one: the Kombucha Basic Starter Kit, whose published contents are a fresh kombucha SCOBY starter, a 1-gallon fermenting jar, a cloth cover and a brewing guide. Tea and sugar are not in that list.

This is a naming problem rather than a trap, and it is entirely survivable — black tea and plain white sugar are a supermarket errand, not a specialist order. But it decides whether the box you open is a complete first batch or two thirds of one, and nothing on either listing flags the difference.
The jar is the best part of it
Craft A Brew publishes more about its glass than most kit makers manage. The gallon brewing jar carries volume markers fired onto the glass at one gallon and at two cups, and a pour-spout lip on the rim.
Both of those sound like styling and are not. The two-cup mark is the one you use every brew day, because the starter tea you hold back for the next batch is a volume rather than a guess — roughly ten percent of the batch, which for a gallon is a little under two cups. A line on the glass turns that from a measuring-jug job into a glance. The pour lip matters the first time you tip a full gallon toward a funnel and it does not run down the outside of the jar.
What is not published anywhere is the jar's dimensions. No height, no diameter, no mouth aperture. For a vessel sold to sit on a kitchen counter under a cabinet, and whose opening your whole hand has to pass through to retrieve a full-width pellicle, those are three of the numbers a buyer actually needs. The gallon jar comparison shows how unusual it is for a maker to publish them, and the mason jar page shows what it looks like when one does.
The picks
What to put in the basket together
The kit as it is actually sold, and the instrument it leaves out. A first batch with no way to read its own acidity is the one gap worth closing on the same order.
Craft a Brew
Kombucha Basic Starter Kit (1 Gallon)
The Craft a Brew kit you can actually buy here: the gallon jar, a live SCOBY starter, the cloth cover and the guide — with the tea and sugar left off the published contents.
Every culture on this site is judged first on one figure: how much starter liquid comes with it, stated as a volume against a stated batch size. Craft A Brew publishes "live SCOBY with starter liquid" and stops there.
That is a real gap rather than a pedantic one. Starter liquid is not packaging — it is the acid that drops a jar of fresh sweet tea out of the range where mold can take hold, and it is the thing that actually carries the organisms. The SCOBY page works through why the liquid matters more than the disc. A culture sold without a published volume is a culture you cannot check against your jar before it arrives.
For contrast, Fermentaholics publishes 12 fl oz against a 128 oz batch and states the ten percent rule it is working to; The Kombucha Shop publishes an 8 oz starter pouch and a minimum six-week ferment before shipping. Both are checkable claims. Craft A Brew's is not — and the fix costs nothing: hold back a generous pour from your first finished gallon and you never depend on a shipped volume again.
The published figure that is unusually honest
Craft A Brew publishes a fermentation time of 7 to 14 days and attributes the spread to temperature and taste. That is a small thing and it is better than most of this category manages, where a single confident number gets printed on the box and the brewer is left wondering why day seven looks nothing like the photograph.
Seven to fourteen days is also simply correct. The first-batch timeline walks the same fortnight day by day, and the temperature page explains why a kitchen in the high sixties pushes you to the far end of that window and a kitchen at 80 F pulls you to the near one. A kit that says "depending on temperature" is a kit whose instructions you can trust a little further.

Read down that table and the pattern is clear. Craft A Brew is the leanest of the three: a very good jar, a culture, and almost no consumables. The other two are fuller boxes that answer more of the first-batch questions for you, and they cost more for exactly that reason.
One note on that table, because it affects what you can act on. The Fermentaholics Complete kit is in it for its published contents, but it was not in stock when this page was written — the listing showed a future availability date rather than a buyable offer. The Kombucha Shop kit was purchasable on the same check, which is why that one and not the Fermentaholics kit appears in the picks below. Stock moves; the beginner kit comparison carries both.
Which is better depends on something about you rather than about the kits. If this is the first thing you have ever fermented and you want the box to carry you, the fuller kit is worth the difference, and the beginner kit comparison ranks them on that basis. If you have black tea and sugar already and you mainly want glass and a living culture, the lean kit is not a downgrade — it is less packaging for your money.
One line applies to all three: no kit on this site includes bottles. A batch is ready one to two weeks after you start it, and the second fermentation needs vessels built to hold pressure, which no kit supplies. Swing-top bottles covers what to order alongside, and ordering them now rather than on day twelve is the commonest scheduling mistake a first-time brewer makes.
Who should buy it
Someone who wants the jar as much as the kit. Volume markers and a pour lip are genuinely useful every brew day, and you will own the jar long after the first culture has been replaced by its own offspring.
Anyone restarting. If you have brewed before and your culture died, this is close to the cheapest sensible route back: glass you will reuse for years and a live culture, without paying again for tea you already have.
A tidy kitchen. Fewer single-use sachets than the fuller kits means less of the price is packaging and less of the cupboard is boxes.
Not someone who wants one box and no decisions. With the Basic kit, tea, sugar and pH strips are all on you — three more things to think about on a first batch.
Not someone who chooses a culture on published figures. If the starter liquid volume is the number you buy on — and on this site it is — Craft A Brew does not give it to you.
The verdict
On hardware this is a good kit, and the jar is better than its place in the range suggests. On documentation it is middling: the fermentation window is published honestly and the contents are published clearly, but the jar has no dimensions and the culture has no stated starter volume, which are two of the three things this site weighs most heavily.
The practical advice is short. Check which of the two kits you are buying before you order; add pH strips to the same basket; order bottles in the same week rather than in the second week; and hold back two cups of your first finished gallon so you are never again dependent on somebody else's starter pour. Do those four things and the kit does its job well.

What it gets right
It is the Craft a Brew kit with a resolvable listing, so the price you see is a live price rather than a search result
Fewer consumables than the fuller kits, so almost nothing in the box is single use
The published 7-to-14-day window names temperature as the variable, which most kit copy does not
A gallon jar and a live culture is genuinely the whole requirement for a first batch
What it costs you
The published contents do not include tea or sugar, which the maker's own standard kit does list
No starter liquid volume is published anywhere — the one number this site judges a culture on
No pH strips, so a first batch has no safety instrument unless you add them to the order
No jar dimensions published, so you cannot check it against a shelf
Skip it if. You want one box that covers the whole first batch. This one expects you to supply the tea and the sugar, and to buy strips separately.
#ad No live price feed yet, so no number is shown rather than a stale one. How this is funded.

What it gets right
pH strips and a pipette in the box mean you can answer “is this safe yet” on day three instead of guessing
The culture is stated to ferment a minimum of six weeks before it ships, which is a long lead time and shows in how fast a first batch takes off
Brew Notes screen-printed on the glass keep the start date on the jar rather than on a sticky note
USDA Organic certification covers the tea, sugar and culture together
What it costs you
No jar dimensions are published anywhere, so you cannot check it against a shelf before ordering
No spigot, so bottling means lifting a full gallon and siphoning or pouring
The most expensive of the four kits here, and some of that is the marker
Skip it if. You already own a gallon jar. You are paying for glass you have, and a culture-plus-ingredients pack costs far less.
Yes, judged on what it publishes, with one caveat about which kit you buy. The gallon jar carries volume markers at 1 gallon and 2 cups plus a pour lip, and the maker publishes an honest 7-to-14-day fermentation window that names temperature as the variable. The caveat is that the Basic Starter Kit's published contents are only the culture, jar, cloth cover and guide — no tea, no sugar — while Craft A Brew's own Kombucha Kit lists tea and sugar as well.
What comes in the Craft A Brew kombucha kit?+
It depends which one you order. The Kombucha Basic Starter Kit publishes a fresh kombucha SCOBY starter, a 1-gallon fermenting jar, a cloth cover and a brewing guide. Craft A Brew's own Kombucha Kit publishes those plus organic tea and cane sugar, and a Deluxe version adds bottling equipment and a funnel. Neither includes pH strips or bottles.
Does the Craft A Brew kit include bottles?+
No, and neither does any other kombucha starter kit on this site. The second fermentation needs vessels built to hold internal pressure, and a batch is ready one to two weeks after you start it, so swing-top or crown-cap bottles are worth ordering at the same time as the kit rather than when the first ferment finishes.
How long does the Craft A Brew kombucha kit take to brew?+
The maker publishes 7 to 14 days for the first fermentation and attributes the spread to temperature and taste. A kitchen in the high sixties pushes you toward fourteen days; a room nearer 80 F pulls you toward seven. A second fermentation in sealed bottles adds a further one to five days.
How much starter liquid comes with the Craft A Brew SCOBY?+
Craft A Brew does not publish a volume. The listing says only live SCOBY with starter liquid. That is a genuine gap, because starter liquid is what acidifies a fresh jar of sweet tea and protects it, and roughly ten percent of batch volume — about 12 to 13 fl oz for a gallon — is the published rule other suppliers work to.
Craft A Brew or The Kombucha Shop?+
The Kombucha Shop if you want the fullest box, a published starter pouch volume and pH strips included. Craft A Brew if you want the better-documented jar and already have black tea and sugar at home. The Kombucha Shop also publishes a minimum six-week culture ferment before shipping, which Craft A Brew does not state.
