Copper Wire Clip Top Airtight Glass Storage Jar

Your sourdough starter will be your baby that you'll need to tend to on a daily basis at first, then slowly dwindle down on. 

There are some requirements for choosing the right container for your starter to live in: 1) the container needs to be see-through, 2) the container needs to be 3-4 times the sourdough starter's height, 3) you will need a lid that doesn't need to be tight-fitting, and 4) you need a wide-mouthed container to easily get your hand in there to clean. 

This glass jar meets all the requirements. Its material, size and shape allow me to see the starter's progress, has plenty of room for adequate growth for and the opening is large enough for me to clean easily. John Lewis also stocks smaller and larger ones than this, but this is the size I use, as it's just the right size for the amount of starter I use and my fridge.
