Cask Ale : Brilliant When It's Fresh... Brutally Expensive When It Isn't.

Here’s a hospitality truth that often gets overlooked.

Cask ale can be a great margin driver, or a very elegant way of pouring money down the drain. And the main reason is simple enough: shelf life.


Three Days to Sell It

Once a cask is tapped and vented, you’ve got three days to sell it at its best. After that, the quality starts to slip, and your guests will pick up on it almost instantly.


The numbers look like this:

  • A 9-gallon cask holds 72 pints

  • To sell it inside three days, you need 24 pints a day


Sell fewer than that, and the last of the cask goes past its best before it’s finished.

Sales dip because the beer isn’t great. The beer gets worse because sales dip. Before you know it, you’re left with a cask that’s cost you money simply by existing.

The Fix: Size Your Range to Your Sales

The fix is simple: build a cask range that reflects your actual daily sales.


Often, fewer casks means better quality, happier guests and less heartbreak when you’re clearing the cellar.


Cask ale is fantastic when it’s handled well, but it isn’t forgiving, and it doesn’t reward optimistic ordering.


Keep your range tight. Keep your beer fresh. Your guests, and your accountant, will thank you.

72 pints, three days, so 24 a day. Size your cask range to your actual sales.
