Beer Batch #4: een pintje d'Abbey

Experimenting with oak

A simple abbey beer, augmented with vanilla infused oak chips. A batch of 5L was made with:

Pintje d'Abbey

  • 1kg Bohemian pilsner malt or any other pils malt, but I still had this around
  • 300g Abbey malt
  • 40g of Saaz hop (definetly try other hops, but again I still had this lying around)
  • a teaspoon of Irish Moss
  • a packet of M47 abbey yeast
  • about 8g of Oak chips

Hopping schedule

The following hopping schedule is used:

The water was brought to a boil before hopping.

  • 20g of hop was added at the start
  • 20 g of hop was added after 30 min
  • the Irish Moss was added for the last 5 min

with a total cooking time of an hour.

Cooling

The brew was cooled to around 20°C, by submersing a cooler in the cooking pot and letting cold water run trough it for about 15 minutes.

Gravity measurement

  • Specific gravity measured: 1.045
  • Alcohol percentage expected: 4.6%

This alcohol percentage is quite low for an abbey beer… (they’re usually around 7%). Means we can drink more though :D

Primary Fermentation

A fastbrew fermenter is used for this batch and secondaryduring primary fermentation. Most of the sediment was already removed during the primary by collecting it by gravity.

Secondary fermentation

After about 2 weeks, the brew was transfered to a glass demijohn. The oak pellet was added to the brew and the fermentation was left for two more weeks prior to bottling.

Bottling

  • priming sugar added in the bottles for carbonization (sugarcubes)
  • bottles filled with laminar flow of pump, with minimal headspace
  • bottles were left for at least 2 weeks before tasting (I’m not a patient man)

Taste and looks

  • Rich flavour, hint of vanilla, very pleasant
  • Nice color, feel, alcohol percentage could be a bit higher.
  • Foam could be better, but plenty of CO2

Recommendations future

  • Take more notes
  • Experiment with other hops
  • Make more of this
