Watch this video of head educator, Rachel Apple, of George Howell Coffee for a brew guide video on the Kalita Wave. She's got a water recipe for all you folks who're using gallon jugs, too!
batwingcrunchies yes I bought the Loudwolf brand and shipping was expensive. The bottle was $6, but the total ended up being $10 with shipping. Potassium bicarbonate was cheaper/easier to find, but of coarse they shipped me Calcium sulfate by accident so now I’m going through the exchange process. 🙄
