Let me start by saying I assume I'm not the first person to start a brew in the evening and find themselves still up in the wee hours tidying up after all is said and done
Last night I did my first AG brew, and only my second brew ever! I followed clibit's Simple AG recipe and scaled it up to make ~10L. I'd done some experiments beforehand and did the mash in my brew kettle in the oven set to 65degC having heated the water first to 72degC using the electric kettle which ended up bang on 65degC when I added the grain.
Worth mentioning, I also discovered Wyeast smack packs need quite an almighty whack!
I got in a bit of a muddle trying to separate the grain from the liquid: Initially I tried using a colander & muslin which was just way too slow. In the end I switched to a fine sieve, spooning the grain into a couple of large bowls as I went and collecting the wort in my big plastic FV.
Similar process for the sparge - add the grain to the brew kettle and add water from the electric kettle to get the temperature back up to 80degC, then back in the oven for 10 minutes at 80degC. Sieve + spoon + bowls again to separate the grain and catch the rest of the wort in the FV.
Having followed the recipe I now had 14L of wort at around 60degC - I knew it would fit in my brew kettle but I had some concerns whether my gas hob (no wok burner, just the large ring) would have enough to bring it to a rolling boil and keep it there (I am an engineer after all!). But sure enough the temperature came up and got it to where it needed to be.
1 hour boil done and hops added (EKG at the start, fuggles 5 mins before end), I dunked the brew kettle in a sink of cold water to cool it, gently stirring both as we went and draining and refilling the sink with cold water from time to time. I got it down to 40degC easy enough but the last 20degC were tougher. In the end I added ice and picnic ice blocks from the freezer to the sink to bring the cold water temp down and force the wort down to 18degC. Cooling took 35mins in the end.
Yeast pitched, FV sealed up and tucked up for bedtime - it's now sitting happily today, bubbling away gently
A few numbers - I calculated the sugar as 30ppg, giving an efficiency *I think* of just shy of 80% (not sure what is the max ppg for maris otter???) and OG=1.056. I think I'm pretty pleased with that, if anything this could end up with slightly higher ABV than I'd like (4.5-5.0% ideal for me). According to the marks on the FV I have about 2.8-2.9 USGal, so about 10.5-11.0L in there.
Lessons learned:
- 10L brew is about optimum for the resources I have
- Sieve works well enough for separating wort from grain; colander + muslin doesn't! (maybe worth - considering a proper mash/lautering tun to make process more efficient)
- Bigger electric kettle would help me heat more than 2L at a time
- Perhaps a wort chiller will help me reduce cooling time
I'm excited to see how this brew turns out!
Cheers,
Matt
