I read this 2.5 gallon one works well: Anchor Hocking Montana Glass Jar with Fresh Sealed Lid, Brushed Metal, 2.5 Gallon https://www.amazon.com/dp/B000RMTG3S/ref=cm_sw_r_cp_api_i_9JVGDb11EH2W6

But I haven’t used it myself so I can’t really confirm...

I started with a 1-gallon. After 3 successful brews, I went for this: https://www.amazon.com/dp/B000RMTG3S

Continuous brew seemed too complicated for me right now. As far as emptying, I'll just siphon it (it'll be ready in the next couple of days).

For 2F, I've been using Honest Tea plastic bottles. For this upcoming large batch, I'm going with something like this

My local Kroger has similar ones for $7 a jar. Might go smaller, well see. Final bottling in standard 16oz flip tops.

I'd avoid "self-burping" - I want the carbonation.

Target and Walmart have cheap offerings as well.
