Chocolate Porter Beer Recipe: 4 Brewing Methods


One of my all-time favorite beer styles. Porter is a rich malty beer, originally made from brown malts and favored by the London river dock workers in the 1800s – hence the name ‘Porter’. As darker malts became used, porter tended towards a heavier, darker beer, eventually diverging into ‘stout’.

Below is my favorite collection of Chocolate Porter recipes, with a version for all levels of brewing.

An old PorterRecipe Notes:

  • The batch size is assumed to be 20 liters (about five gallons).
  • Brewhouse efficiency is assumed to be 70%.
  • Bitterness and hop contributions are given values at set alpha acid levels, with the assumption that you cool your wort after brewing.

If you need to calculate percentages and make adjustments, try this page for Mac or PC resources.

  • 400g cracked Chocolate malt (specialty grains)
  • 200g cracked Dark Crystal malt (specialty grains)

  1. Using a Medium grain-bag, steep specialty grains in 20 liters of water while you bring to the boil, stirring frequently. Just before the boil, remove specialty grains.
  2. Add dry malts, stirring to ensure no clumps remain. Be wary of boil-overs at this time.
  3. Add bittering hops. For best results, use a hop-sock.
  4. After 45 minutes, add aroma hops. For best results, use a hop-sock.
  5. After 10 minutes, add finings.
  6. After 5 minutes, shut off boil, create whirlpool, and cool into fermenter.
  7. Add yeast and ferment as per usual
  8. Low carbonation (6g sugar per liter if priming naturally)

 Partial Mash Recipe

This one is a little darker, and just a little bit thinner. You can always beef this up with some more amber malt or DME. It uses only fuggles hops and has a bit more bitterness to it.

This one is a more robust porter again. Darker, maltier, and hoppier, it’s a great new-age porter.

  1. Chocolate beer? now there is a idea! and something that just bust my diet! and found a new hobby! might just make it my mission to brew a pizza flavoured beer!

    Seriosly speaking where would I start out and how? where can I find equipment for a starter without spending too much on equipment? Here there is amarket for decent beer as either watery tasting or bitter, no real craft beer at all, except when super expensive due to being imported!

    I will have to be careful, as home brewing is illegal in Thailand, – hey it happens but it is still very illegal!

    • Hi Derek,

      I cannot recommend that you brew at home, as it is illegal in your country of residence.



  2. Two of my favorite things in the world are beer and chocolate. Combining them into one thing is just…wow! Now, can you add pizza in there as well somehow? I’d be a very happy camper!

    I certainly admire those who can home brew. I tried the “beer in a bag” thing but it turned out…not good. But, if I as a new home brewer, I really value this post!

    • Thanks Mike, glad to hear this is useful to you!

      Please don’t be discouraged, everyone’s first beer is different than what’s expected. It’s all about identifying what you didn’t like in the beer, and how to change it for the next attempt!

  3. Wow, that sounds absolutely delicious, it made my mouth water! I love the idea of making your own beer, my boyfriend wants to try it even more……I think it’s a good idea for a christmas present for him!

    I’m guessing its fairly easy to get up and running with the kit?

    • Thank you so much for your comment Louise!

      It can be very easy or you can be quite technical about it. Check out the Equipment page for inspiration and details!
