G70 FAQ’s

Will my filter get blocked up with hops?

We have designed the G70 and the filter so that you do not need to use hop socks or hop spiders and can use as many hops as you like. Please note, you should only be concerned if your re-circulation actually stops not if it slows.

How long should it take to get a decent rolling boil?

It should take 40 to 60 minutes from sparging. tip is to switch the G70 to 99°C while you are doing the sparge to speed up the time it takes to get to the boil. By the time you finish the sparge the G70 should be close to temperature.

What efficiencies can I expect from the G70?

This depends a lot on your grain bill, grain crush and recipe. Our overall testing has yielded efficiencies between 75 - 85%

What is the maximum grain bill I can brew with?

The maximum is 17 kg (37 lbs). With a grain bill this size, the key is to add the grain very slowly while stirring to avoid dough balls forming. Because there is more grain, it will also take a bit longer to gelatinise

What is the minimum grain bill I can brew with?

minimum of 8 kg with the standard pipework. We would advise against going lower than 8 kg (17 lbs) of grain. The overflow pipework only reaches a certain depth and the top plate is designed to fit into the overflow inlet which sits on the overflow pipework. This means the top plate only goes down as far as the overflow pipework does. As a result, with a smaller amount of grain (less than 8 kg (17 lbs)) the top plate will sit a bit higher than the grain bed. You will need to add more water until you see the water reach the top plate. Be sure to record this extra water amount and change your calculation accordingly as you will need to reduce your sparge volume by this amount. Alternatively, you can use the micro pipework available which is explicitly designed for small grain bills. It would be best if you used the standard calculations when using this pipework.

What is the boil off rate?

For the G70, the boil off rate is Litres/hour
