The aim

To brew an Australian Sparkling Ale using an off the shelf home brewing system

Same scaled recipe Step mashes to utilise system capabilities Use systems as close to off the shelf spec as possible

What this is not about

• Absolute experimental control from start to finish
• All beers post brew day were managed at home by the individual brewer

(think fermentation vessel, temperature control, kegging technique, over sampling!)

• A comparison of brewing methods such as chilling
• A CHOICE magazine style review
• All systems make beer so “good choice”!

A New Recipe

Lots of recipes out there: Aussie Home Brewer forum “Recipedb – Coopers Sparkling Ale Clone” started by AndrewQLD in 2009 BYO Magazine – Australian Pale Ale article by Tony Wheeler (an Aussie) in 2009 Modern Homebrew Recipes – Gordon Strong (2015)

• References ANHC 2010 in the description
• Six malts from four countries

……. Australia wasn’t one of them

So what did we land on?

OG = 1.047, FG = 1.006, IBU = 35, ABV = 5.5% Pale Ale 87.5% (Joe White) Wheat 5.9% (Best Maltz) Dark Crystal 1.9% (Thomas Fawcett) Cane Sugar 4.7% (Woolworths) Pride of Ringwood hops - 60min boil addition Calcium Sulphate for crisp hop bitterness White Labs WLP009 Australian Ale

(One large starter was split between brewers. More control than all brewer’s culturing Coopers yeast)

Mashing

We used a step mash: Dough in @ 39°C for 20 mins Mash 1 @ 52 °C for 15 mins Mash 2 @ 63 °C for 60 mins Mash out @ 75 °C for 5 mins

Brewday

Brewday was 13th August 2016 Video SYSTEM_WARS_FINAL_03

Chilling

Picobrew Zymatic – Cooling program with the corny keg in a bucket

• f ice slurry

Grainfather – Used included counterflow chiller Robobrew – Used included immersion chiller Braumeister – Used an immersion chiller Wort cooled to 20C before pitching yeast Top tip – Silicone hose not rated for mains water. Lots of laughs.

Did we hit our numbers?

• All system OG were between 1.045 and 1.047
• All FG between 1.005 and 1.007
• Kegs were naturally carbed using cane sugar
• Turns out we were too conservative and didn’t add enough sugar so kegs

were connected to CO2 at 10psi to ensure appropriate carbonation

System observations

• All the systems are relatively easy to use

and set up.

• Manufacturer and supplier how-to videos,

forums etc

• Compact size of machines makes clean up

simple

• Hose out for Grainfather, Braumeister and

Robobrew

• Inbuilt cleaning program and dishwasher for

PicoBrew Zymatic

• How much do you want to spend?

Where to next for off the shelf systems?

• Smaller – PicoBrew Pico 5L, Braumeister 10L
• Focus on brewing indoors in the kitchen
• Pre-packaged ingredients to attract new/casual brewers
• Pico, BrewArt, WilliamsWarn

And the winner is…….
