Great kit for your sourdough journey

“This is a great sourdough starter kit OR for someone whose been making sourdough for years, like myself. It comes with everything you need, including measuring cups, a scraper, and even a scrubber that fits the jars nicely. I LOVE the super wide top for ease of stirring and for getting starter out of the jar. I’ve always used wide mouth mason jars and this is much better access. The heaviness of the jar is so nice. It doesn’t feel like I’m going crack it if I knock it too hard accidentally. The scraper that comes with it is probably my favorite part 😆. It scrapes every nook and cranny perfectly to get every bit you need. The breathable top is perfect and it looks nice sitting on my counter too. The stick on thermometer is handy as it will give you an idea of how quickly your starter is going to rise. I also really like the band on the outside to mark where my starter began so I can easily tell how much it has risen. One time I did have it sort of stretch out and it wouldn’t stay on the jar. I just washed it in the sink with my dishes and once it dried, it was good to go again and stayed in place. All the measurements on the side of the jar seem a little overkill for me because when feeding your starter it’s by weight, not cups or ML. Overall- this is well worth your money to buy and looks nice in the counter too.”

Great for sourdough newbies like me

“I bought this jar for the wider mouth. It makes it so much easier to clean than some of the other sourdough jars. I also love that it came with the brush because that is really helpful when trying to clean off the dry and hardened starter that gets on the sides of the jar after pouring. The glass feels thick and sturdy and I like that it has all the measurements and places for you to write your feeding ratio & other things like that. The temperature strip seems to work well & the kid having a little temp guide is also helpful to a newbie like me. The color of the band that goes around to mark feeding times/starter level is stretchy enough to be easy to move around and I also like the color since most that are sold online are just black. The little linen cap is cute. Over all super happy with the upgrade in my sourdough starter jar.”

Might be a “beginner” kit but experienced bakers will love it as well!

“Everything included in this kit is created to set you up for success! Wide mouth jar makes accessing start easy for baking and feeding. Cloth cover allows start to breath and screw on lid is perfect for cold storage. The band included can be used to mark your starters beginning level and includes day and time marks to remind you the last time the start was fed. The included brush makes cleanup super easy and the spatula allows sides of the jar to be scraped clean and everything mixed perfectly. It even includes a stick-on thermometer so you know how warm/cool your start is to optimize feeding peaks. Recipes are included. This is a great kit and well worth the money spent to make sourdough start maintenance a breeze.”

Perfect for the novice or pro

“What is not to love about this kit?!? It seriously has everything you need to be a sourdough pro. For starters, the instructions are simple yet thorough AND they are printed on durable paper so it can be on the kitchen counter without getting destroyed. It also tells you what to do or expect throughout the whole process and how to tell if your starter is ready! The jar is sturdy, large, and easy to read. It also comes with an awesome thermometer sticker so you understand what is happening to your yeasty goodness. The band that you put on the jar measures how much it rises and for some reason it brings me more joy than when I measure my kid’s growth each year. It also has a cool cloth cover with elastic edges that is easy to slip on and off. Finally, the tools are awesome. My favorite thing is the spatula. It is perfect for scraping the sides of the jar and is the perfect length. All in all, this is the perfect gift for anyone, including yourself. If you already have starter, it is great to use instead of the old mason jar because it not only works great but also looks good.”

A great tool for beginners!

“I have been baking sourdough to a little over two years. I will be teaching a sourdough class in my community and I was looking various starter kits for my students. This sourdough starter kit has everything you ne s to get started! You can track the temper of your starter without needing a thermometer. It comes with tools that allow you to track your feeding schedule. It even comes with measuring cups if you don't have a scale to measure your flour and water in grams. I also really love the silicon stir spatula that is included in the kitchen. It helps keep your feedings neat and tidy. It includes a pamphlet with sourdough starter care instructions as well. All in all this is an excellent value for anyone starting out!”

Must Have!

“I was using a mason jar and thought I was being "extra" by wanting this, but I am so glad I did. The jar has everything you need especially if you are new to sourdough or have a busy life. The jar is well labeled and thought out. Measurements up the side help me track growth of the starter. The band slides so I can track daily where I am. I didn't notice the thermometer that you install on the glass jar until I got it out of the box. That is amazing because it not only tells you the current temperature of your starter but what the previous temp was so you know where it is in the energy process of feeding and discarding. The cloth cap is great to regulate air flow and gas release. It also prevents something from falling in the dough or a fly landing on it. The rubber scraping tool is so perfect - I made a rule in the house not to use it for anything else. I recommend having 1 or 2 of these on hand if you do sourdough. There is also a place to name your starter on the jar once it is active. LOVE IT!”

Great starter jar

“I have been using this set for a few months now and I love it. I needed something to help me start my sourdough journey and this was perfect. I love the wide mouth jar, makes it a lot easier to pour starter in and easier to clean, which the brush they give you is perfect for. The band is helpful as well, although I only use it to help me see that the starter has doubled. They also give you a linen cover, which is perfect for active fermentation. The only thing that doesn’t seem to work is the thermometer but I don’t use that anyway. Overall, this is a great starter pack and so happy I bought it. I would highly recommend.”

Four months in...

“Bought this set back in January when my previous starter got moldy. It was missing that feeding tracker ring but everything else was included. After following the initial instructions, I had a bubbly starter within a week! Her name is Doughlene and she's beautiful. 😆 Might just be my kitchen counter conditions, but I've found that using the stretchy fabric cover causes the top of the starter to dry out between feedings. So now I put the metal lid on loosely (just set it on top) and the starter is much better.”

Simple concept for my sourdough starter

“This jar is just the right size and has everything on it that I need to keep track of my starter. I love the markings on the jar, the cloth and metal lid. The rubber scrapper is very nice and works great. The scrub brush for the jar is just the right shape. Sometimes that starter can really stick. The book that is included with the jar has some easy to follow great recipes. I am very happy with the quality of it all.”

Perfect Starter Jar

“Why did you pick this product vs others?: I absolutely love this starter jar. It is easy to clean and work with. I really appreciate that it came with a cloth lid and a standard jar lid. When my starter is active on the counter we use the breathable cloth lid, but when I leave town and have to put it in “hibernation mode” in the fridge, the typical jar lid is fantastic. The temp gauge is perfect, as it helps me anticipate rise times and I love the elastic band for calculating rise (growth). I use this product everyday and it really has made my adventures is sourdough that much better. If your getting into sourdough I highly recommend this product.”

Great product for sourdough….

“Well, I do t know about you, but I’m not new to bread baking, but I am new to the sourdough world. Finally I have a good starter, and have one recipe so far, that works…it’s a. work in progress..as they say. But the kit I bought somewhere only contained a small, fairly tall glass jar, which I thought would work…well, now that my starter has taken off, that jar just seemed inadequate. Also I read that if you want more starter, you have to increase the water/ flour ratios at the weekly feeding. I did that, and suddenly, there’s more starter, and now the need for a bigger jar. (My first one, since it was tall and not real wide, was hard to mix in the stuff to feed it.) Anyway, I ordered this one…after I watched the videos that several of you posted- thanks ladies for that!! Now I knew I needed this one. Long story short- now my starter is very big! This jar is nice and wide…I like the screw on lid. A set of measuring cups is included….thats great, cause I always need extra! All in all, I really like this a lot. My only comment is why can’t they include a cloth apron with that cool” Super Baking” written on it? Wouldn’t that be great??! :) Cheers to you bakers out there!”

Great high-quality kit for beginners

“I honestly didn't know much about sourdough starters before looking into this product, so I really appreciate the amount of detail in this kit. Unlike trying out a random jar from the kitchen, which might not provide the correct conditions, this kit has a well-designed container that's ideal for fermentation.

PERFECT SET FOR BEGINNING BAKER

“I have long wanted to make sourdough bread, but the issue of a starter seemed too complex. I could imagine having to purchase a powerful mix from......somewhere..... and then having to baby it for........ever.

Useful but not all components are necessary for maintaining starter

“I used this jar for my already established starter. While the volume measurements on the jar are not useful for feeding starter (starter should be fed based on weight), it is actually quite useful in tracking how much the starter has grown since the last feeding. My elastic band feeding tracker was quite loose and did not stay on the jar at all. It seems a little arbitrary to have the band if you can write the time and date fed and mark the level with a dry erase marker directly on the jar itself. There's even spaces on the jar to write that information. I tried using the cloth lid and my starter did not rise at all. I fed the starter again put the metal lid on (didn't screw it on), and it rose. I was skeptical of the jar thermometer sticker but it works, I can't say if it's accurate but it definitely does change as the temperature changes.”
Verified purchase
★★★★☆

Good product with fair warning

“My sourdough tracker arrived yesterday. After washing out I continued my feeding process. I am new at this. I want others to know that the cloth cover provided does not provide the needed protection. My starter rose then deflated with a dried skin on top. I’ve always used the plastic bowl covers found in multiple sizes at the dollar store. I’m afraid to use the loose lid for a rise. Like the band provided but am not sure I get anything from the stick on thermometer. Can’t see that any of the colored temps ever change. Maybe I can get clarity from the manufacturer.”

Useful set for sourdough starting

“The set contains a starter jar that has measurement markings, a vertical line to sync the elastic band with to track the last feeding, some measuring cups, a thin stirring spatula, and a cleaning brush. I wasn't able to get a starter going on my first try using the instructions from the included booklet. I suppose that is normal when you haven't done something before. My second try, I used a small packet of sourdough starter powder that I received as a gift in addition to the whole wheat flour I used and was able to get that going. It feels a little bit like cheating but it worked. The tracking band is handy for schedule-impaired individuals like myself. Googly eyes not included in this kit.”
★★★★☆

Where is the starter? Jar kit is nice tho.

“Starter jar and accessories feel like a good quality but I really wish “kit” included starter dough. Yes you can make your own with 3 ingredients but starting a new kit takes a bit of work each day for 5 to 10 days to get mature culture. Did not want to wait on new setup so bought starter to jumpstart the process. Just wish it had it already. Jar and cover is nice, spatula and brush are easy to grasp, well packaged.”

Great Starter Jar for Sourdough, but Lid Seal Needs Improvement

“This 34oz wide mouth sourdough jar has been a very helpful addition to my baking routine, especially as someone who appreciates practical design. The wide mouth makes feeding and mixing the starter much easier and less messy than narrower jars I’ve used, and the included guides and recipes are a nice confidence boost if you’re still learning. I also really appreciated the extras—the scraper is surprisingly useful for getting every bit of starter off the sides, and the cleaning brush makes it simple to keep the jar in good shape. Shipping was impressively fast, so I was able to get started right away. My only real disappointment is the quality of the lid’s inner seal: it came off after just one wash, which raises concerns about durability over time. If the manufacturer improves the seal, this would be close to a perfect sourdough starter jar.”

“The only thing not so good about this jar is the rim of the jar is chipping. It came a bit rough but every time I use it and wash it it seems to chip more. I even hand wash it. I still give it 4 stars because I love the size.”

great starter jar

“I am SO scared of starter. Like for real. Nervous wreck. Having this available to walk me through was a game changer! Seems like good quality and I think I would buy as a gift for others too! I hope I become a master baker with this!”

Overall Good Kit

“I like the whole kit. Everything looks quality made except the included measuring cups. Those look pretty cheap and I’ll likely toss them, to be honest. Looking forward to using the rest of the kit. I appreciate the included sourdough recipes.”

It’s a wide mouth jar!

“I love the jar because the opening makes it easy to add the ingredients. The temperature gage doesn’t work. I do not understand the purpose of it. Four stars because of the temp gage.”

Superbaking Sourdough Starter Jar

Great product it's just small

“Overall the product is very good but what I will say is that the jar is noticeably smaller and harder to use the band and markers and the temperature gauge while useful isn't very necessary and I didn't find it very useful overall what was Nice about it is the little custom cover and stuff it makes it very aesthetic but otherwise the glass is really proof doesn't allow any air to go in or out and it was also very sturdy”

Super Baking Sourdough Kit: Great Start, Jar Design Falls Short

“My wife really wanted to love the Super Baking Sourdough Kit, and it’s nearly a 5-star product for its complete setup—everything you need to start baking sourdough is included, with clear instructions. However, she is giving it 3 stars because the jar’s non-straight edge design is a major drawback. It’s hard to keep clean, and if you don’t scrape it thoroughly, red mold forms after just 2-3 days. A straight-edged jar would make this otherwise excellent kit much better.”

This is nice, but it's just a jar with a shower cap and some spoons.

“So, sure, if you want to get a kit, this is a nice one. It's got everything. The little shower cap is perfectly fitted to the jar. But I mean, y'know, you eat spaghetti. You've got a jar laying around the house. You can fashion a shower cap. You've got spoons and such. Do you really need this? No. On the other hand, it would make a nice gift. Everyone loves sourdough, right?”

Good for gifting

“Update 2025-05-19 (3*): Well, it lasted almost five months. The glass jar had a chunk just fall off of the bottom edge while being taken out of the fridge. It's not an expensive item, but I don't think I've ever had a glass container fail like this, which leads me to believe we're really unlucky or there was a flaw in the glass. Original review 2024-12-25 (5*): My son really enjoys baking and we got this for him as a gift. All of the pieces could be sourced elsewhere, but it presents well and gives you everything you need to start. Maybe most importantly, at least for younger kids, are the clear instructions on what to do for each day. There's no yeast included (nor should there be!) because a true sourdough starter will be unique to the area, taking bacteria and wild yeast from the air to produce a unique blend. The scraper is well shaped for the provided jar, the thermometer strip is really convenient, and the "bread hat" (as my son calls it) fits the jar comfortably. If you just want to make a sourdough starter, you probably don't need a set like this. If you want to start sourdough with a child or are giving this as a gift, it's a solid option.”

Not my favorite.

“I wanted to love this jar, but I don’t love the inside bend along the top. Between that and the grooves, it requires a little more scrubbing to get the jar 100% clean. Considering it’s specifically marketed as a Starter Jar, it would have been perfect if it were smooth all the way to the lip (inside and out). I ended up using another brand that is a little more expensive (with a gasket and glass lid), and is easier in the cleanup. The thermometer was a nice touch, but mine didn’t seem to work.”

Nice kit, not sure ok to use on warming plate.

“Nice kit and accessories. Can mark last feed day and time and temp. Only problem is that the bottom of the jar broke while I was mixing and almost all of my starter was lost all over the floor. It might be because I was warming my starter in jar on a warming plate. Check with company to see if using a warming plate weakens the glass before buying.”

Cracked within first month

“After less than a month of using this a crack appeared at the bottom of the jar. I only hand washed and it only sat on the counter or in the fridge. I really liked the band (although it did stretch out a bit) and the thermometer, but I have resulted to just using a jar from jam that is a good size instead.”
