Ugh, I relate hard to that sinking feeling as you turn your keys and pray the car starts. Glad you got it taken care of! I got a Hario Cold Brew Coffee Pot and it's great, the filter has caught even super finely ground coffee.

I'm all about the Hario Mizudashi cold brew maker It's the price of one of the "large glass jars" and so much easier.

I like the circulation method, I think for less than $30.00 USD Hario Mizudashi is as simple as it gets to making a strong ready to drink cold Brew, I use 120grams coffee to 1000ml of H2O
