Brewing wheat beer with the Coobra CB25

So the other day we had our second session with the Coobra Craft Brewer 25. This time we tried out the full volume, 25 liters of wheat beer was on the menu.

The recipe:
3,5 kg Pilsner (4.5 EBC) Grain
3,5 kg Wheat (6.0 EBC) Grain
0,5 kg Cara Plus 10 (10 EBC) Grain
10 g Hallertauer 4.8% boil 60 minutes Hop
25 g Saaz 4% Boil 30 minutes Hop
15 g Saaz 4% Boil 5 minutes Hop
1 package Safbrew Wheat (DCL/Fermentis #WB-06) Yeast

Before we started, I put both the Coobra CB25 and the Coobra Sparge water heater through the cleaning procedure described in my previous post.
Once everything is cleaned up it was time to start.

This was our first attempt with wheat grain, and I decided not to taste any of the grain before we started (given that I broke my front tooth last time on a single grain.. thank god for Swedish dental care!)
As much of our beer so far has tasted similar, we also decided to try out some new hops. Especially the Saaz was a new buy. Hopefully it will turn out good.

The water pump didn't clog this time, it worked like a charm through the whole process.

When it came to boiling, we didn't have the opportunity to boil at a window (winter outside) and the CB25 is a bit too tall to fit under a standard cooking hood we ended up building some temporary steam channel out of corrugated paper. Successfully boiled away 7 liters in 1 hour, so good results.
Project for next time is to build something more lasting in steel plate, watch this spot for details ;).

Pre-fermentation tasting was promising. Just wait and see now, hopefully bottled and ready for christmas, but probably more like new years.

Cleaning the equipment

The wheat grain makes a real mess. After a normal batch it is usually no big project to clean the equipment after use, but the wheat seems to attach itself better to the surface.


Using beersmith we have estimated that the efficiency is more like 58-60% then the stated 75%. So next time we should probably try out with a lower efficiency number.

Until next time: Challenge yourself to do something new

I bought this product myself and this is my opinion on them. I am in no way affiliated with the manufacturer of this product.
