Ist Brew Devil Brew

[Isolec82]

Did my first brew with the Brew Devil yesterday - A simple bitter from Graham Wheeler's book. Recipe was for 19l and gave total volume as 26.6l and Mash volume of 8l. I added the dead space below the tun of 7l and mashed 15l. I then sparged with the balance to make up to 26.6l. I had to add a further 6l of water later to bring the volume up to brew size of 19/20l and bring the og down to target 1038. What am I doing wrong? Bubbling well now! Would you expect that much evaporation?

You probably aren't doing anything wrong.

Under the right circumstances (a warm and yet windy day), on a rolling boil of 30 litres for 70 minutes, I can lose up to 8 litres.

With the losses incurred from removing wet hops and leaving the cold break debris behind in the Boiler, I often have to add a few litres of water to the boiled wort to bring the volume back to the 23 litres that I normally brew.

Thanks for the reassurance, I had done a 9o min boil with the wind whistling in the window and out of the back door. Pleased I hit the predicted gravity for the volume so must have got that bit right!
