Brewing with Gladfield Malt, Gabi’s first Porter!
DIASTIC POWER (DP) 150-250(WK)
Measure how active the enzymes are in the malt
Diastic Power = Not enough enzymes activities= no conversions of sugars = not enough feed for yeast
Diastic Power = Too much enzymes active= yeast eats all = no residuals for mouth fee = thin beers
The craft beers are so hopped, you need mouth feel and residual sugars so your beer is balanced
The main stream beers use adjuncts (non malted grain) to save money (cheap beer) so High DP means that theycan convert the sugars from these grains as well =watery beers = no flavours left in the beer
FAN (Free Amino Acid) 120-140 mg/l
Measures how much food you have for your yeast The amount of soluble amino acids
FAN means that you won’t have enough feed for the yeast = low fermentability
FAN means too much fermentability = thin beers= give you off flavours for long shelf beers
In craft beers you want residual sugars/body/flavour
KOLBACH INDEX 37-40
It measures how good the was malted
Ratio between soluble N / Total N
KOLBACH INDEX means too small protein particles = thin body beer
How well the protein was chopped
KOLBACH INDEX gives you problem with filtering/ haze issues = the maltster haven’t done a good job
FRIABILITY 90-95%
It measures how well modified your malt is
It shouldn’t be hard to crack a maltwith your finger nail.
If it is too hard means that your malt wasnot modified = no conversions = poor fermentability
MOISUTRE MAX 5%
High moisture base malts will lower the gravity of your beer so you will needmore malts to brew the same beer.
It is important part to store all yourmalts in air tight containers and keep to the best before dates.
You should only crush what you are going to use any leftovers should be disposed
Moisture and Malts don’t go together
INTACT HUSKS
*TOFFEE MALT should always be crushed mixed with your other malts because it is a high moisture content malt, really unique.
Measuring pH of your Mash is really important to keep your Yeast happy!Use Sour Grapes to control your pH (1% Sour Grapes lowers 0.1 pH)
