    Best fermenter/conditioning configuration

    I'm looking to open a brewpub with some off site distribution. I expect to have 5 brews at any given time, including at least one lager. Total annual output will be between 3500 - 4500 bbl. I'm looking at a 10 - 15 bbl brewing system but wanted to get some thoughts on-

    1. How many fermenters / conditioning tanks would you recommend?
    2. What size of each?

    I appreciate your help...

    Calculation for Brewhouse Size & Number of Fermenters

    For a 15 bbl system, you have to brew many times per week.

    Let's do some calculation.

    Formula for calculate your system size:
    System size (brewhouse size) x number of brews per week x 50 weeks per year = Annual Production

    For a 15 bbl system:
    15 bbl x 3 brews/week x 50 weeks/year = 2,250 bbl annual production

    If brew 6 times a week, your annual production will be
    4,500 bbl.

    Another way to find out the size requirement:
    4,500 bbl / 300 days = 15 bbl per day
    4,500 bbl / 360 days = 12.5 bbl per day

    How much beer are you going to sell and how much to
    sell per pint in your brewpub?
    Use these to calculate: 1 pint = 16 oz
    1 liter = 34 oz
    1 bbl = 117 liters = 248 pints

    Use the above to figure out your system size requirement, and brewing frequency.


    Your overall parameters as:
    80% ale, 20% lager
    Ale- 14 days fermentation
    25 cycles per fermenter per year
    50 weeks/ 2 weeks fermentation period = 25 cycles
    Lager- 28 days fermentation
    12.5 cycles per fermenter per year
    50 weeks/ 4 weeks fermentation = 12.5 cycles

    For calculating the number of fermenters:

    Annual production / (system size x number of cycles
    per year) = number of fermenters

    Your example:

    Ale: annual production = 4,500 bbl x 80% =3,600 bbl
    3,600 bbl per year / (15 bbl x 25 cycles per year) = 9.6 = 10 fermenters

    Lager:
    900 bbl per year / (15 bbl x 12.5 cycles) = 4.6 = 5 fermenters

    For a total of 15 fermenters.

    Double sized to 30 bbl will cut the number of fermenters.

    If you want 5 beers on tap, you will need 5 serving tanks.

    We have a brand new, never been used, 2000 liters (17 bbl) turnkey system available, it has everything, and sell for near used equipment price.
    Email me for more information.
