I finally had a chance to do a brew using my own home grown perle hops.
Last years harvest was lost to an infection in my brewing equipment to the point I threw out my 2 fermenters and purchased three new fermenters, as I lost a couple of brews and could not find the source, so assumed it was from the old fermenters (one was around 12 years old).I did not have time to do an “All Grain” brew so I purchased some malt extract from my local Home Brew store (with new owners - so I thought I’d help out and purchase from them).
Ingredients:
• 1.5kg Black Rock Amber Malt Liquid extract (only because they had no pale extract left)
• 1kg Light Dry Malt extract
• 400ml Glucose syrup (only because it was in the cupboard and I wanted to get rid of it)
• 400grams Crystal malt (80L I think) to add some body to the beer (probably way too much crystal)
The hops were added as approximates only, for 2 reasons
1. I don’t know the alpha-acid content so no point measuring any way
2. My small scales are broken so I had no choice
• 40grams 60mins Perle Whole hop flowers
• 20grams 12 mins Perle Whole hop flowers
• 15grams 1min Perle Whole hop flowers
• Packet of SAFLAGER dry yeast (temp range 11-15˚C - good for winter as the current temps here are a max of 15˚C with lows of 5˚C)
Method:
Heat 2 pots of water
Main pot 15litres water
Grain pot (just a smaller pot) 2.5litres
Added grain immediately to the smaller pot, to extract the malt slowly as the water heated so not too much of the grain tannins get into the brew, and it was easier to do the grain separately rather than trying to strain 20 litres of hot wort later to get the spent grains out.
Add Amber malt to main pot when it was starting to get close to boiling, boiled a kettle and rinsed the amber malt tin out with boiling water into the main pot.
Added dry light malt to main pot (dry malt is great but a little painful to dissolve, I usually don’t worry about it too much as once the wort boils it soon dissolves)
Stir the grain now and then to stop the grain burning at the bottom of the pot
When the main pot begins to boil (takes awhile with only small stove elements - did I mention my normal ‘wort kettle’ is out of action, needs a new tap as I had to steal it to fix one in the house) add 40 grams of hops and allow to boil for ~38 mins.
Ensure you keep stirring the grain pot, once it reaches almost boiling, strain into main pot and rinse grains with hot water to get all of the good stuff out.
This causes the main pot to stop boiling, but it soon came back to the boil
Add 20 grams of hops
Continue the boil for 10-11 mins then add the last of the hops
Turn off the stove
Put lid on the pot and put pot in large container of cold water, leave for 15 mins
Check temperature of the water - it may heat up considerably,
change the water with more cold water if it does get too warm (~25˚C),
leave for around 45 mins, change water again.
Sterilise fermenter with “one-shot” acid based steriliser or your preferred steriliser, and rinse with hot water (not really necessary with one-shot but I like to do it anyway)
Put 5 litres of cold water into fermenter with garden hose at high pressure - to try get a bit more oxygen into the water, as most of the dissolved oxygen in the boiled wort will be gone.
Strain wort into fermenter (stainless pasta sieve works well), then add water to 24litres (once again at high pressure for aeration).
Check temp - 18˚C - perfect!!!
Take SG reading - 1.050
Rehydrate yeast in 100ml luke-warm water (24˚C) for 15 mins add to fermentor
Put lid on with airlock and put into old broken refrigerator to help keep temperatures more constant
Fermentation was a little slow starting - about 24hours before a krausen started forming (froth on top of brew) but for a lager yeast I’ve found this quite normal
So now we’ll see how it goes
———————————————–
I intend to do another brew on the coming weekend, and what I’ll do is rack the current brew to another fermenter to finish it off, and drop the new beer onto the active yeast cake in the 1st fermenter, there will be so much active yeast in the yeast cake the new beer should start fermenting strongly within hours, from experience I will not be putting a heavy wort onto this yeast cake, I’ve had too many ferment so actively that it ‘crawls’ out of the airlock, even at temps as low as 10˚C!!!
Stay tuned for postings of previous sucessful recipes and of course new brews….
