A repeatable process for brewing RFA Colombia 5LB in large batches, covering ratios, grind size, and the checkpoints that keep every pot consistent.
Quick answer
To brew RFA Colombia 5LB consistently, lock in a 1:16 coffee-to-water ratio by weight, grind medium for drip, and brew in batches no larger than your equipment handles evenly. Weigh both coffee and water every time instead of scooping.
Why weight beats scoops for 5LB batch brewing
A 5LB bag invites eyeballing, but volume scoops drift with grind setting and settling. Weighing coffee and water removes that variable, so the same ratio produces the same cup even as the bag empties. For a medium roast like RFA Colombia, small dose errors show up as sourness or bitterness because the coffee's clean, creamy profile leaves little to hide behind.
Match grind to your batch size
Large batch drip coffee needs a medium grind, but the word medium covers a range. If your brewer basket drains slowly, coarsen slightly; if the bed drains fast and the cup tastes thin, go finer. Because RFA Colombia is a medium roast with distinctive acidity, a grind that is too fine can push that acidity into sharpness rather than brightness.
When to adjust rather than repeat
Consistency does not mean never changing anything. If you switch brewers, batch size, or water source, expect to re-check grind and ratio. Keep the same recipe for the same setup, and change one variable at a time when you do adjust.
Step-by-step large batch brewing
- Weigh your coffee and water: Use a 1:16 ratio by weight: for every 100 g of coffee, use 1600 g of water. For a 12-cup batch, start with 100 g coffee and 1600 g water. Common mistake: scooping by volume, which can swing the ratio by 20% or more. Write the weights on the bag so the next batch is repeatable.
- Set a medium grind: Grind just before brewing and aim for a medium setting that looks like coarse sand. Checkpoint: the brew bed should drain evenly in roughly 4–6 minutes for a drip batch; if it stalls, coarsen one step.
- Preheat and rinse the brewer: Run a short cycle of hot water through the empty basket to warm the carafe and rinse the filter. Common mistake: skipping this on large batches, which drops the brew temperature and flattens the cup.
- Brew in equipment-sized batches: Do not exceed the capacity your brewer handles evenly. If you need more coffee than one cycle, brew consecutive batches rather than overloading the basket. Checkpoint: an overloaded basket leaves dry patches and uneven extraction.
- Stir and taste before serving: Give the finished pot a gentle stir to even out extraction, then taste. If it is sharp or sour, grind finer next time; if it is bitter or hollow, coarsen. Change only one variable per batch. Keep a simple log of weight, grind setting, and taste so adjustments stay deliberate.
