Supplies & Equipment
This great little lid is quite functional - it fits most wide mouth mason, Kerr and Ball canning jars
and is perfect to convert your jar into a strainer or sprouter! We also make specialty strainers
and sprouters of our own, which we find work even better. You can find them in our store.
Just tip jar and let the kefir strain out, leaving the grains behind or sprout wheat or other grains to
eat and use in making more digestible breads at home. Made of culture-friendly food-grade
We always have some of this stuff on hand at our home. Cheesecloth (butter muslin) always
comes in handy with straining, and can double as a breathable lid for your cultures. This is the
unbleached, natural good stuff. We love this stuff because you can wash it and re-use it - very
cost friendly and eco-friendly.Also a perfect filter for jelly, cheese making and storage, making
Greek yogurt (thick yogurt) and even meat roasting, basting, stuffing and poaching.
With some of this unbleached natural twine you can make your own bags out of muslin to
hang and strain kefir to make cheese.
Muslin also comes in already made muslin drawstring bags, which double great as re-usable
bags for keeping any household items like buttons, toys, fishing tackle. We offer packs of these in
our supplies section of our store, too. We like to also use these to carry snacks in, instead of
using (and wasting) tons of plastic bags.
Soup socks are another perfect option for keeping something in thats immersed in some kind of
liquid medium. Soup socks are a lot like the cheesecloth, but they're more stretchy and not as
tightly woven (and also reusable for quite a few times). If you've ever made home-made soup you
know the chicken and bones fall apart everywhere- sticking the whole chicken plus your veggies
and fresh herbs in these stretchy re-usable socks keeps everything intact. What a brilliant
creation. Great for sticking in fruits or veggies for flavoring your kefir or kombucha.
Bulk quantity unbleached coffee filters still remains one of the best (and cheapest) options
for finely straining out any kombucha yeast strands to get the most pure kombucha when
bottling. Just rest inside a strainer like one of the ones above. Also doubles as a nice breathable
lid for kombucha.
Excellent stainless steel strainer (culture friendly material). We own one ourselves - the sturdy
strong handle, fine mesh size and multiple size choices of this strainer makes this ideal for
straining kefir and kombucha. Also rests nicely atop most standard bowls due to the hanging
knob opposite the handle.
Bamboo strainers are a good alternative if you want to avoid all plastic and metal materials
when straining your ferments - may or may not work well with milk kefir.
We don't recommend plastic strainers usually because virtually ALL plastic strainers' holes are
too large. This is best for kombucha or water kefir (if your grains are consistently large - though
yeast strings or kefir grains may pass through), has a sturdy handle and is also collapsible. We
do have a special nylon/plastic strainer in our supplies section of our store which works perfect
for all of our cultures and has a finer mesh.
A bowl with a pouring spout and nice grip on the handle and bottom - really nice to have for
collecting your strained ferments and then being able to pour them into your bottling jars. This
one holds 8 cups and even has measuring notches inside - convenient and handy bowl.
Ingredients & Flavoring
Although kombucha seems to do best with white sugar, you can try organic whole cane sugar
(rapadura). This particular brand actually composts their sugar cane instead of heating it (like
most other companies), which preserves more of the nutritional value of the sugar.
Organic Turkish apricots make a yummy and nutritious addition when you are bottling your
kombucha and flavoring it. Barry Farm offers many, many other high quality and usually organic
dried fruits to flavor your kombucha as well at very good prices. You can purchase small or bulk
This brand of organic flavoring syrups is a delicious easy way to add flavor to your kombucha
(and of course milk kefir, yogurt, water kefir and popsicles too). Of course fresh fruit and
ingredients (or juices) are optimal but for difficult to recreate, fun flavors try the Hazelnut,
Huckleberry, Pomegranate and Irish Creme.
Cranberry Juice Concentrate is delicious and has many health benefits (and high vitamin C),
this one is our favorite because no funny stuff is added. Juice concentrate is better for flavoring
than juice in the case of milk kefir since you can use a smaller amount, and not risk diluting or
making the milk kefir too runny and loosing its creaminess. They also make pomegranate,
blueberry and cherry.
For making your own juice (veggie or fruit) this juicer is really the way to go - one of the best
juicers for serious juicing without breaking the bank. For flavoring (and secondary fermenting) with
your bottled ferments this device can really create some interesting and incredibly healthy and
This is one of the best brands of flavor extracts and amazingly its cheaper than non-organic
store brands when you get it bulk online. For example this Fair Trade Certified vanilla extract is
the product of premium organic vanilla beans grown in southern India by small farmers who are
committed to sustainable, bio-dynamic agriculture. They have many other flavored extracts as
There are so many jars to choose from out there, but we recommend thick-walled glass jars
which offer more protection against explosion when storing and bottling your ferments. Brands
that make superb jars include Ball, Kerr, Bormioli Rocco and Anchor Hocking. This pack is a
good size to start out with if you can't find it at your local store. We have jars available in our
supplies section of our store, too.
Swing top bottles are great for building carbonation (and flavor) in your kombucha. This comes in
a pack of 12 and each holds 16 oz (2 cups) - just right for bottling and flavoring! We also offer
these in our store.
An airlock is a great cheap little necessity if you are thinking of fermenting beer, wine, or lacto
fermented veggies such as sauerkraut or pickles! We make our own sauerkraut with this.This
also is wonderful to use to ferment kefir, kombucha, and gingerbeer. It simply keeps the ferment
cleaner than a cloth lid, while still expelling built up carbonation from the fermenting process.
This insulated bottle sleeve is great in the winter or summer to help regulate the temperature
of your fermentations such as milk / water kefir or kombucha. Comfortably holds a quart jar.
Flexible ice packs - you can cut to fit whatever you need to stick them in or around. This is
great for all kinds of purposes including wrapping around kefir jars to cool them in the summer.
The problem with many ph test strips is that due to the hype in testing body acidity/alkilinity
there are many cheap and unreliable 'gimmick' brands out there. If you are wanting to accurately
test the Ph of any of your cultures or even for other purposes this brand is used by chemists and
is as accurate if not more so than as a descent ph meter (unless you're willing to shell out
After discovering that yogurt machines can be finicky and heat up too hot, we've come to rely on
this trusty cooler - also which seems to perform the best for regular cooler usage too
(outperforming other comparable coolers). We just fill it with water thats 110°F, stick in our jars
and in 4 hours we have tons of beautiful home-made yogurt. Of course, there's bigger sizes but
this one holds 4 of the quart jars, which is a good starting amount for most, and fits perfect in the
backseat floor area of a car when you use it for 'real' cooler purposes.
We like this measuring cup because you can push sticky stuff out of it without touching it with
anything else (great for cultures where contamination is an issue). Perfect for measuring honey,
molasses, yogurt starter, kefir grains or sourdough starter.
The best and cutest popsicle molds (bpa free). Everyone seems to adore these because of their
perfect size, cute shapes and colors and of course the fact that you can make tasty, fun treats at
home over and over with these. Homemade frozen yogurt, kefir and kombucha popsicles taste SO
much better than regular popsicles of course too! :) Or just freeze some fruit juice in these molds
for a quick cheap summer treat!
Fascinating and fun book full of helpful and truly unique fermenting advice. It focuses on the
flavor, nutrition, and craft of live-culture foods. There aren't a whole lot of books out there on this
topic - we ended up owning this we liked it so much.
Sandor Katz (author of the above mentioned book, Wild Fermentation) takes fermenting to a
whole new and more in-depth level. His most current book chalk full of fascinating info on
cultures from around the world, how to obtain them, and how to work with them. Beautiful large
reference book for any fermenting enthusiast, including several photo sections.
Organic bulk green tea (not loose leaf) at a good price for brewing your kombucha. White tea
lends a delicate and delicious flavor to kombucha too (but is more pricey). This brand also offers
a good affordable bulk white tea.
Kombucha does very well with a blend of black tea and green tea, or all black tea as well. Choice
Organics makes a nice Black Tea.
South African Rooibos (Red Bush) tea is a good option if you are looking for a non-caffeinated tea
to brew kombucha with (some people have good success, though kombucha does best in green
and black tea).
We've found this to be the most reliable brand for fresh, unsweetened organic coconut shreds
(great for flavoring). We've noticed many other brands and even organic bulk bins in stores tend to
have rancid/old coconut shreds that do not do well with the ferments.
We tentatively recommend this coconut water. Compared to the other brands most agree it has
the truest fresh young coconut flavor and is handy to use to make coconut kefir if you cannot
purchase young coconuts. However, the background of this company is vague, and some of the
times we tested this we turned up with rancid coconut kefir. We highly recommend just buying
the real thing if you can.
Knudsen Family Just Juice is our favorite line of juice because it is just that... just the juice of
the fruit on the label! Why so few companies do this is beyond us, but this is healthy stuff and
excellent for flavoring your bottled kefir or kombucha!
One of THE best maple syrups out there - and we're talking Vermont fresh from the tree quality.
An excellent natural sweetener for kombucha (after bottling it).
Raw honey is so good as a natural sweetener mixed with freshly bottled kombucha and has
substantial health benefits both for your skin and for consumption. Although we recommend
finding local raw honey (which also can help improve seasonal allergies), this is an excellent and
highly recommended choice of raw honey.
This is an especially great set of culture-friendly bamboo wooden tongs with gentle grips on the
ends- made well and perfect for grabbing your slippery kombucha mushrooms out of their jar
(metal and rubber are less gentle and more slippery to use).
A refractometer is more accurate but much more costly than a hydrometer. This is a nice one if
you are wanting to really get into the science behind the brewing of cultures.
When in doubt, just peel it, but otherwise Veggie Wash is a nice way to remove some of the
pesticides, waxes, chemicals and soil (which is especially important if you're dropping a lemon
into your kombucha or water kefir, for example).
Reusable straws - great to have around for water kefir and kombucha. Always come in handy,
and never have to buy straws again - made of reusable, durable polycarbonate (dishwasher safe).
This is a popular little hydrometer that does the job of measuring sugar/alcohol content of your
brewing (great for water kefir, kombucha, gingerbeer plant, wine or beer). It's a bit fragile but for
under $5 it's quite the deal for how well it works.
This dehydrator stills remains one of the best on the market and is perfectly suited for drying
(and not worrying about preservatives/sulfites) any kind of fruit or veggie you pick up at your store
or farmers market (or garden!). Dried fruits and veggies without sulfites are perfect for added
nutrients and flavor in your water kefir and kombucha ferments.
