If you check out the graph on the site, you can see what I'm talking about. The graph is of "aquarium temperature over time", so the slope is proportional to refrigeration capacity. It's steepest in the high 20s, and gets flatter as the temperature drops. Extrapolate the (negative logarithmic)...

Yet he talks about solubility as the cause of lowered viscosity....

I'm not sure the aquarium cooler will go cold enough. More specifically, any refrigeration system loses refrigeration capacity as it approaches it's lowest possible evaporation temperature. So, I would be extraordinarily surprised if the aquarium cooler would have remotely near the necessary...

I can't seem to stop myself... gotta give the new brewery something to do! PALLET 1 - Joe White/Best Maltz/Simpson/Briess etc 1. PRATTY - Joe White Pilsner 2. PRATTY - Simpson Maris Otter 3. PRATTY - Joe White Vienna - 1/2 bag (split with MATTYH77 ) 4.BREWHART - Simpsons Maris Otter 5.BREWHART...

I'm in brooky, work in Wetherill park and have a ute so Penrith is fine for me. Happy to pick up yours for you and drop at your place.

Also don't forget pressure drop across checkvalves. can be as much as 5 PSI.

Can I ask a quick couple questions for the uninitiated: Is the pickup for the grain on May 17? What happens if we don't get enough people for 40 bags per pallet?

I hope you don't get any stones in your malt... I'd rather stall a motor than shred a mill.

I don't really worry about the time too much, because there are so many other variables that are unknown which affect the dissolution rate just as much. Just an approximate 30-60 seconds and a flow rate that produces nice even small bubbles from the air stone, rather than giant turbulent...

Mmm, I was warned early on that it's rather carcinogenic when inhaled. That said, West End, Malt Shovel use DE when I was last there (couple years ago). West End have a new brewhouse now, so I doubt very much that they still use DE. Vietnam Breweries (owned by Heineken) also used DE. Tooheys...

Your water is great for brewing. It's far easier to add salts than to subtract (unless you have a reverse osmosis system). Beersmith is probably oversimplifying this a bit. I can't help you with how to use that as it's not the tool that I use. The ratio is "extremely malty" at 0.6, but the...

I believe the GI of maltose to be far higher than glucose. Glucose is 100, maltose was around 120 from memory. So all of the sugars in malt impact more on your glycemic system more than glucose. I think fructose is ~110. "Low carb" is simply "high attenuation". My view is that beer isn't a...

I can't speak for CUB, but every brewery at Lion is a little bit different. Remember that Lion has a lot of smaller boutique breweries too. You're right though, for a sugar source it's cane sugar. Typically liquid (50-60 degrees Brix) from bulk tankers for Tooheys. Malt Shovel and Little...

I've never had a fermentation fail to start. Sometimes it just takes a while for it to become visible. Sometimes, if you use a particularly prissy lager yeast for example, it never really looks like anything's happening because the fermentation is so slow. Othertimes, if you have a highly...

I can help, to get us started you should find out or measure the below: Surface area of your pot, total which will be exposed to air movement (not base. You can probably ignore lid as it will have negligible effect as it contacts air/steam on inside) Surface area of your pot which touches wort...

That's right. Liquid sugar is common is aussie lagers, rice in asian lagers, corn in american lagers.

This is my bread and butter. Yes it will work, but I doubt 10 minutes will be enough. Give it a go though. The limiting factor is the heat transfer rate out of the vessel, which is maximised by the blast air flow. Assuming it's a true blast freezer. The capacity of the refrigeration is likely...
