So it was brew day yesterday. The day must be counted as a success as I have 24ltres of beer sat behind me just stating to ferment.:thumb:
So how was the day?
Used my normal HLT to heat sparge water.
First issue was mash temp. I used the control panel to set water temp at 71c (which is my normal strike temp) and added the grains. Double check with another thermometer showed mash temp was 60c, so upped the temp controller to kick the heater in and stirred until temp got to 65c. Switched off and left for 90 mins. Temp at end was still 65c. I do have some extra insulation on the outside which would help maintain the temperature.
Drain and sparge. There is no automatic rest for the grain basket but rather a lid with a hole that has to be put on to hold the basket to let it drain. This means you have to lift with one hand so as you can insert the lid, or get an assistant. Draining worked fine apart from not being able to see the water level. Had to remove the grain basket to check level to see how much sparge water to add. Unfortunately there are no volume markings, so how much to add was a bit of a guess. Sparging went well using my normal rotating sparge arm although the wort was murky, probably due to the stirring at the beginning of the mash. I probably could have recirculated it through the grain bed but didn't bother.
The grain basket was easy to empty, just put a 25l green recycling bag (I used two for extra strength) over the top and tip it up, job done. Cleaning was bit of a fath as the perforated plate is fixed and you end up chasing the last few grains around the inside.
Boiling. I planned to fit my short bazooka hop filter but hit snag. It you fit it at the beginning it fouls the grain basket and if you try to fit it after sparging the boiler is full of hot liquid. In this instance I drained the boiler so as I could fit it. Could have also use one of my hop spiders but in this instance because the wort was a bit turbid I wanted to use the hops as an extra filter. I set the temp controller to 107c and left it to reach a good boil. I only used the 1500W element and this worked well.
Cooling. It comes with an immersion chiller. Rather than connect to a tap I used a cool box with cold water in and a small submersible Aquarius pump to circulate. Half way through I changed to a single pass from the cool box to a spare FV, with this I could turn the pump off and let the siphon effect pull the water through. This uses much less water as the flow is slower. I used my inkbird to check on the temperature of the wort as the Klarstien was switched off at this point and I didn't want to rely on the controller temp display. I forgot to time the cooling as I was busy doing other things but reckon it was about 45mins to get down to 23c.
Overall it was a successful brew day which used a lot less equipment and room than my normal kit. There are some things I need to look at for next time:
- Double check the controller temp display against another thermometer.
- Look at re-circulating the mash back through the grain bed (will depend if it is murky next time as hopefully I won't be doing the extra stirring).
- Try the one pass cooling from the start to see if it shortens cooling time.
Fingers crossed with this one as I am also using a Brett/saison liquid yeast (first time with a Brett and liquid yeast) and planning to add some cherry puree (again another first) :cheers9:
