Start with a throughput target
Use the Keg capacity calculator first when the target is still a guess. It ties the machine count to one crop stack, processing cycle, and deadline instead of copying a shed layout blindly.

Keg crafting plan
Build the machine count your harvest actually needs
A target such as “84 Kegs” is only useful when it becomes a chest checklist. This page subtracts machines already built, applies the in-game recipe to the remainder, and shows the material that stops the next craft.
Count finished bars, not loose ore
The Keg recipe consumes Copper Bars and Iron Bars. Enter the bars already ready to craft; furnace time, ore, and Coal remain separate farm-planning decisions.
Treat Oak Resin as a timed input
If Oak Resin is short, enter the mature Oak Trees you already tapped and your deadline. The planner compares the regular seven-day cycle with the Heavy Tapper three-day cycle, then shows when the gap closes or how many trees the deadline requires.
Crafting recipe and Oak Resin collection timing only · does not price Sheds, ore, Coal, furnaces, Tappers, or travel time · all entered counts stay in this browser.
How this calculator works
One Keg needs 30 Wood, 1 Copper Bar, 1 Iron Bar, and 1 Oak Resin.
Subtract built Kegs
Only the gap between the target and the Kegs already on the farm needs a new recipe.
Apply the recipe
Multiply the remaining Keg count by 30 Wood, 1 Copper Bar, 1 Iron Bar, and 1 Oak Resin.
Subtract chest stock
The result shows what can be crafted immediately, the limiting material, and the exact shopping or gathering list still left.

Sources & formulas →Common questions
Before you use the result
What materials are needed to craft one Keg in Stardew Valley?
One Keg requires 30 Wood, 1 Copper Bar, 1 Iron Bar, and 1 Oak Resin. The recipe is unlocked at Farming Level 8 in unmodded Stardew Valley 1.6.x.
Does the calculator subtract Kegs I already built?
Yes. Set the total machine target and the number already on the farm. ValleyMath applies the recipe only to the difference.
Can I enter materials already stored in my chests?
Yes. Enter current Wood, Copper Bars, Iron Bars, and Oak Resin. The result shows how many Kegs can be crafted now and the exact shortage for the full target.
Does this include ore, Coal, furnace time, or shop prices?
The material result stops at finished bars, and the Oak Resin section adds collection timing for mature trees that are already tapped. Ore smelting, Coal, shop prices, Sheds, and the cost of crafting Tappers remain outside the result.
Why is Oak Resin often the bottleneck?
Wood and ore can be gathered or purchased in larger bursts, while Oak Resin takes seven days with a regular Tapper or three days with a Heavy Tapper. Enter your tapped Oak Trees and deadline to see whether the next collections cover the Keg target.
