I use a cheap fan heater ($15 from Coles/Bunnings/etc) in my fridge which is triggered from my digital thermostat, set to heating mode. It heats the fridge up quick and the fan circulates the air giving a more stable/even temp. Cheers, Damon

Not sure what the Motorola motor driver circuit costs but as an option you could use either the top or bottom circuit of the attached to drive a fan up to 3A (3A might be a bit of overkill...). It uses a 555 timer to adjust the PWM applied to the fan and hence the speed for those that are...

Hi There fellow brewers, Just wondering what people's experience in fermentation temps for Belagian ales (golden and strong dark) is? I've read starting the fermentation at around 18degC, hold it for a day or 2 then let it rise naturally until complete... That way you get a good balanced...

Hi Darren, I'm always on the lookout for new sources of malt. Can you please give me a price list and freight costs for within Melbourne. I'm looking at least 25kg of the Weyermann Bohemian pils and 25kg of Bairds MO ale malt, with a kilo or 2 of specialty malts. Cheers, Damon

Hi Guys, Just wanted you to share your experiences using Aussie malts like Joe White and Powells, compared to Weyermann, Maris Otter or other European malts. The Aussie malts are much cheaper but is the quality as good? Will you get similar flavours when making hefeweizen for example? Any...

thanks everyone for your help. the numbers look a lot better this way. Damon

ok, so I should be using the volume of all water used from scratch, ie, mash water + sparge water to calculate efficiency, not the final wort volume? this would take into account all losses due to grain absorption, kettle losses, etc...

Pat, The last brew used 5.4kg grain for a total volume of 22L with gravity of 45 which gives a value of 179. What are the theoretical values you normally use as the ideal case? Cheers, Damon

My brewing setup uses 25L food grade plastic pails with heating elements in the bottom. The base diameter is about 32cm and the top diameter is about 36cm. My first mash lauter tun was 2 of these buckets, one inside the other with a heating element in the bottom bucket. This had a dead volume of...

Anyone got ideas on improving extraction efficiency with all grain brewing?? I'm getting 55% consistently regardless of whether I brew a pilsner of strong ale
