How many barrels does a 10-barrel microbrewery need to sell?
Calculate microbrewery break-even from saleable barrel equivalents, channel value, contribution, tank capacity and fixed operating cost.
Published by StartFigures · Editorial standards · Correction guidance
The StartFigures 10-barrel microbrewery case needs about 148 saleable barrel equivalents per month to cover simplified operating costs. At $1,050 of blended realized revenue per barrel equivalent and a 58% contribution margin, each sold barrel contributes $609. With $90,000 of monthly fixed costs, the continuous threshold is 147.8 barrels per month.
The mature case sells eight barrel equivalents per operating day across five days per week, or about 173 per average month and 2,080 per 52-week year. This is a sales equivalent. It does not mean the brewhouse produces eight barrels every day.
The $1,050 barrel value, eight-barrel-equivalent day, 58% contribution and $90,000 monthly fixed cost are authored assumptions. They are not a production guarantee, taproom forecast, distributor order or local price.
Define one saleable barrel equivalent
One U.S. beer barrel contains 31 gallons. A saleable barrel equivalent converts taproom pours, packaged product and wholesale kegs to a common liquid-volume unit after production loss and quality hold. The channel ledger then applies the realized price and direct cost for each product and route.
The matching paid workbook uses the E21 manufacturing engine. Every beer product line has its own sold units and price. The same liquid cannot appear as production output, packaged inventory, taproom sales and wholesale sales at the same time.
Bridge brewhouse nameplate to sold volume
| Stage | Record | Question |
|---|---|---|
| Brew | Recipe, brew turns, wort volume and raw materials | What entered fermentation? |
| Cellar | Tank-days, transfers, loss, conditioning, hold and release | How much became saleable beer? |
| Package | Kegs, cans or bottles, fills, breakage and cold inventory | Where is each released gallon? |
| Sell | Taproom, packaged and wholesale units, price, returns and collection | Which released volume became recognized revenue? |
A 10-barrel brewhouse does not automatically produce 10 saleable barrels per turn. Fermentation space, conditioning time, cleaning, yield, cold storage, packaging, quality release and channel demand may bind first.
Calculate barrel-level break-even
At a 58% contribution margin, $1,050 of realized revenue leaves $609 contribution per saleable barrel equivalent after ingredients, packaging, excise, freight, loss, payment fees and channel-linked costs.
$90,000 ÷ $609 = 147.8 saleable barrel equivalents per month. Across five operating days per week, that equals about 6.8 barrel equivalents per operating day.
At eight daily equivalents, monthly volume is 8 × 5 × 4.33 = 173.2 barrels. Monthly revenue is about $181,860, contribution is $105,479, and simplified operating surplus is about $15,479 before depreciation, financing, income tax, replacement capital, inventory timing and distributions.
Stress channel value and contribution
| Case | Assumptions | Barrels/month |
|---|---|---|
| Lower channel value | $650/barrel · 58% margin · $90,000 fixed/month | 238.7 |
| Base | $1,050/barrel · 58% margin · $90,000 fixed/month | 147.8 |
| Higher direct-sale value | $1,500/barrel · 58% margin · $90,000 fixed/month | 103.4 |
| More direct-cost leakage | $1,050/barrel · 48% margin · $90,000 fixed/month | 178.6 |
| Higher fixed cost | $1,050/barrel · 58% margin · $110,000 fixed/month | 180.6 |
The lower-value case would require more volume than the base operation sells. That may occur when wholesale replaces taproom volume, packages cost more, losses rise or discounts and returns reduce collected revenue.
Use official production context carefully
Census defines breweries as establishments primarily engaged in brewing beer, ale, lager, malt liquors and nonalcoholic beer. The 2023 national employer table reports 5,218 brewery establishments. It does not establish local taproom demand, wholesale access or saleable yield. Census NAICS and 2023 County Business Patterns.
TTB states that a business must qualify before brewing beer for sale and publishes operational reports derived from brewer filings. Those requirements and national reports do not certify one site's utilities, wastewater, state and local approvals or commercial demand. Brewer's Notice and Beer Reports.
TTB also publishes current federal excise-tax rates and qualifying reduced rates. Eligibility and tax treatment must be verified for the actual brewer and removals. TTB tax rates.
Read the five-year case
| Year | Revenue | Operating result |
|---|---|---|
| 1 | $1,050,000 | -$342,500 |
| 2 | $1,620,000 | -$81,600 |
| 3 | $2,184,000 | $186,720 |
| 4 | $2,420,000 | $265,700 |
| 5 | $2,650,000 | $343,500 |
The next test is at least 150 saleable barrel equivalents across intended direct and wholesale channels. Reconcile raw material, brew and tank time, yield, quality release, package conversion, inventory, realized price, returns, labor and collection. Add tanks or packaging only after the records identify the real bottleneck.
The Brewery / Microbrewery case contains the complete $1.55 million allocation and forecast. Its evidence register separates sources from assumptions, while the business plan and financial model explain qualification, production and product-line adaptation.
