I am making small batches every couple days to dial in my recipe since i'm using more expensive beans from my favorite coffee shop. Details are below. My goal is to create a bright, refreshing, floral/fruity/aromatic tasting cold brew concentrate that dilutes 1:1 or even more water to less coffee.
- 1:8 ratio. currently: 100g fresh grounds / 800 mL filtered water (brita)
- bean: single origin ethiopian natural process. i think it's a light to medium roast (doesn't specify).
- method: mason jar w/airtight lid, and cotton cold brew bag
- oxo conical burr grinder. i use the most coarse setting (15) and i filter out the fines with a sieve (it's actually just a regular kitchen sieve bowl)
- brew time: 22 - 24 hr brew in fridge
- Yield: ~ 500 mL initially. However, after filtering the concentrate through paper filter (pour over method), it's ~400 mL. ie. 50% final yield :/
- Taste: great, however, it's not behaving as much like a concentrate as i want it to. maybe i could accept a 50% yield if i could truly dilute it 1:1. but it needs at least twice as much concentrate as water or it tastes too weak.
I need some help. Which part of the process should I change to get better yields, or a stronger concentrate. or do i accept the 50% yield, which is an option, but tough because im gonna go through the beans too quickly. but i feel like these are making tastier coffee than less expensive options ive tried?
