How do I calculate roast batch yield and weight loss?

Divide roasted weight by green weight to get yield, and the remainder is your roast loss. A batch that goes in at 100 lb green and comes out at 84 lb roasted has an 84 percent yield and 16 percent loss, typical for a medium roast. The Roast Batch Yield and Green Bean Shrink calculators return both figures so you can convert green purchases into packable pounds and price accurately instead of guessing at a flat loss number.

How much weight does coffee lose during roasting?

Most of the early loss is free and bound moisture, followed by organic dry matter as the roast develops. Light roasts commonly lose 12 to 15 percent, medium roasts 15 to 18 percent, and dark roasts 18 to 22 percent. The Moisture Loss and Green Bean Shrink calculators separate the water driven off from total shrink, which matters when you are reconciling green inventory draw-down against finished roasted pounds packed.

How many roast batches can I run per shift?

Batch count depends on roast time plus turnaround for charging, dropping, and cooling. If a roast cycle runs 12 minutes and cooling and recharge add 5, you get roughly 3.5 batches per hour before breaks. The Roast Curve Capacity calculator turns cycle time and shift length into realistic batch and pound output, and pairing it with Line OEE shows whether the packaging line, not the roaster, is actually capping your day.

How do I control bag fill giveaway on coffee and tea packaging?

Giveaway is the average grams packed above declared weight, multiplied across every bag. Overfilling a 12 oz bag by just 4 grams on a line running 30,000 bags a week gives away over 250 lb of coffee, real money at wholesale cost. The Bag Fill Giveaway calculator quantifies that loss in pounds and dollars so you can tighten checkweigher targets while staying above net-weight compliance limits.

How do I calculate finished cost per pound for roasted coffee?

Start from green cost divided by roast yield, since shrink raises the effective green cost per roasted pound, then add Labor Per Pound, Energy Per Batch, packaging from Valve/Label Cost and Nitrogen Flush Usage, and any Scrap/Rework Cost. The Finished Goods Cost calculator combines these into a per-pound number, and the Margin calculator sets your wholesale and retail pricing against it with the yield loss already baked in.

How does shelf life factor into roast batch and packaging planning?

Roasted coffee degasses and stales, so batch size should match how fast a SKU sells to avoid packing product that ages out. The Shelf-Life Batch Risk calculator weighs batch size against demand and remaining shelf life to flag overbuild, while Nitrogen Flush Usage and the one-way valve costing in Valve/Label Cost protect freshness. Undersized cupping checks miss drift, so Cupping Sample Rate helps set how often to pull and evaluate a sample.
