Weck Tulip Jars 1 Liter - Large Sour Dough Starter Jars with Wide Mouth - Suitable for Canning and Storage - 2 with Glass Lids

Both the tulip and the straight versions of these Weck jars are absolutely made for sourdough starters. The wide mouth and lack of ridges make it perfect for scraping down the sides of the jar. They are a breeze to clean. The lid can be made airtight by using the rubber gasket and fastening it all with metal clips. It can also be used with just the glass lid, which allows for pressure to escape when fermenting a sourdough starter. There is plenty of room for your starter to grow and be happy in this 1-liter jar. The only drawback is that these jars are a bit pricy on Amazon. If you're able to get them in person, you could definitely get a better deal for your money. Thankfully, mine arrived undamaged after shipping.

I first saw these on TikTok and thought, “Do I really need bougie jars for flour and water?” Turns out — yes, yes I do. I originally bought this set as a thank-you gift for a friend deep in her sourdough era, and she loved them so much that I ended up ordering another set for myself. Now my adult daughter and I are actually enjoying the starter process — and bonding over the adventure of it all. The size is perfect, the glass is sturdy, and the wide mouth makes stirring, feeding, and cleaning so much easier than mason jars. No more crusty threads or sticky starter cement. They look beautiful on the counter, feel solid in hand, and somehow make me feel like a real adult baker instead of a chaotic kitchen goblin. If your sourdough starter has been testing your patience, these jars will absolutely restore a bit of peace (and pride) to the process.

I really love these Weck tulip jars for sourdough starter. The 1-liter size is perfect for an active starter and gives plenty of room for rise without overflow. The glass is thick, sturdy, and high quality, and I love that it’s clear so I can easily track bubbles and growth. They’re easy to clean and feel very durable, definitely a big upgrade from random jars. Con: The jars are on the heavier side, especially once filled, so they’re not ideal if you plan to move them around often or store them on a high shelf. Overall, a great investment for anyone serious about sourdough. I’d definitely buy them again.

These Weck jars are perfect for casual or home sourdough bakers. The glass is thick and durable, and they provide a reliable container for sourdough starters. They’re also easy to clean and don’t retain odors, making them versatile for other kitchen uses. The only limitation is their size—they’re not suitable for commercial baking or large batches, so they work best for small-scale home baking. Tip: Use them to maintain your sourdough starter, and label each jar if you have multiple starters. Verdict: A high-quality, versatile jar for home bakers. Reliable and attractive, but not intended for commercial-scale baking. This was easy to assemble (no assembly required) and I would highly recommend purchasing this for aspiring sourdough bakers!

These are probably the best jars on the market for sour dough! The size is perfect and easy to use and mix in. Extremely heavy duty and being able to choose if it is an air tight jar or not is a great added bonus.

I bought this set of two Weck jars to use for my sourdough starter. Each week, I take out 50-75 grams of starter to feed in one jar, marked with a green rubberband to indicate the starting level, and use for my next loaf of bread. I put the discard in the other jar (with a purple rubber band around it to mark the level) to use in biscuits, waffles, English muffins, etc throughout the week. It’s a great system to keep my sourdough well-fed and maintained. The jars have nice, wide mouths, which makes it easy to get the starter in and out. They’re thick, sturdy glass that won’t break if you bump them into something or tap a spoon against the edge. I use the glass lid and rubber gasket without the clips, so the gasses released by my starter don’t build up pressure inside the jar. It is exactly what I needed, and I’m glad I went with this option, rather than some of the plastic options I saw labeled as sourdough starter jars. Both jars (my active and my discard) live on the top shelf in my refrigerator, since I usually don’t bake bread more than once a week, and don’t want to have to feed/discard every day. I usually feed Friday evening and leave the active jar out overnight to double, then bake with it on Saturday.

I’m in love with these Weck jars! They’re beautiful, sturdy, and the perfect size for sourdough starter or homemade pantry items. The glass is thick and the lids seal really well. They look gorgeous on my shelves and are super functional. A must-have for any home baker or kitchen organization lover.

Son lo que estaba buscando, de muy buenos materiales!

Thank you so much

Well made, perfect size and wide mouth for storing, feeding and stirring sourdough starter.

La publicación dice que son dos frascos pero al final sólo llega uno. Hablé con servicio a clientes de Amazon y me dieron un cupón de 100 pesos ya que decidí no devolverla, sin embargo veo que todavía dice "two jars" y pues qué tremenda gatada. En cuanto al frasco, es de excelente calidad, lo puedes usar para fermentar cositas o simplemente guardarlas; es una gran alternativa a los mason jars ya que el aro naranjita de éstas es de hule y *reutilizable* al contrario de las mason. Verdaderamente un muy buen producto pero le doy cuatro estrellas porque el encabezado está mal.
