NZ Bitter

[ExpatBrewer]

Today a partial mash bitter based on a Coopers OS Lager can. It's by far the cheapest form of extract where I live so I use this as a base for most of my PM brews.

This is a 2nd version of the one pictured below. The 23 litre brew is modeled on a best bitter but using NZ malts and hops:

1.7kg Coopers (OS) Lager 44.7 %
1.5kg Gladfield Ale Malt 39.5 %
200g Gladfield Biscuit Malt 5.3 %
200g Gladfield Medium Crystal Malt 5.3 %
100g Gladfield Dark Crystal Malt 2.6 %
100g Sugar 2.6 %

10g Waimea [16.50 %] - Boil 15 min
25g Motueka [7.00 %] - Steep/Whirlpool 30 min

5g Gypsum
Nottingham slurry


Undecided option:
25g Riwaka - Dry Hop 3 Days

90 min mash @65ºC

| OG=1.043 | IBU=29 | EBC =18 | ABV=4.4% |

Good evening! Is that a lot of gypsum?

I use it to go some way to compensate for what's lacking in my town supply water and it also helps with pH adjustment too. I use as much 10g depending on the brew I'm making. It's not a complete water adjustment regime by any stretch but I figured after studying a water analysis chart and crunching the numbers that it's a good base addition for most brews. I know of others using the same water who are more particular than I adopt more complex water treatment including iodised salt, gypsum and Epsom salts. I used to brew with the water as is but I think the gypsum has been a worthwhile minimal addition for my water. :geek:

One of my New Years resolutions: measuring more! And keep detailed records.
