Saturday brew day was a long one, nearly 5 hours. I wanted to have another crack at the Baltic Porter. Chas wasn’t available so my mate Kilan came over to give me a hand.
Kilan has done a bit of home brewing over the last few years. Most of his equipment is in storage. He’s still been able to make some cider and brought over a bottle to share. Will talk about that later.
Was fun to have Kilan over for the arvo. We worked on a few things that neither of us had done before. Had a couple near misses and a whole heap of improvisation. By the end of the day we had bottled the Hoppy Heart IPA and brewed what we felt would be a really good beer.
The last time I did the Baltic Porter it was a 10 litre batch. The beer came out nice enough but lacked some body. The beer had a little too much sweetness. There was room to adds more complexity. In short, there was a lot that could be tweaked.
Given the relative ease of the full grain mash at Chas’s last week I thought of trying a mini mash. The recipe was upping to a 17 litre batch and ingredients to match. That meant a lot more grain. Last time the recipe only had Crystal grains, which can’t mass by themselves. With advice from Chas I decided to include some Chocolate malt, which I believe can mash. So all 2kg of the grain went in to mash.
Kilian was a champ and crushed the chocolate malt grain. The only thing I had was a mortar and pestal which meant some grain got crushed. Hope that doesn’t make much difference.
The Crystal grain went into a grain bag and into the pot. The Chocolate grain got thrown into the bag then all was stirred in. Mash was done at 68°C and had 5 litres of water. Wow, that grain soaked it all up and expanded like a balloon! Mash went for a full sixty mins.
While waiting for the mash to finish we bottled the Hoppy Heart IPA. The final gravity came in at 1.019. With the carbonation drops it will be 6.4% alcohol. And before you ask, yes I will move to bulk priming soon.
We opened the apple cider that Kilan brought. That was an interesting drink, and I mean that in all ways. We chilled it right down and was cold most of the time. First up it tasted like alcoholic orange juice, not like apple. Sort of super sweet and slightly tart. The smell was pretty bad, almost like something off. As it warmed up the cider became more like apple and more dry. Much better cold. I think something might have gone wrong with the yeast and / or fermentation. Let’s see euchre same thing happens to my cider.
Back to the brew, and mash was done. Only problem now was how to sparge the grain. And there was a huge amount. Was fortunate that the kettle we have at home has different temperature settings with the lowest being 75°C. So we used that and poured the water over the bag of grains. Each time we tried to press out as much liquid as possible, but we didn’t really have the right set up. After a few kettle’s worth of water at said temperature there was a lot of volume for the boil. I would have liked to do more sparging, but the boil pot just wouldn’t hold it all.
So onto the boil. Earlier I realised that I didn’t have the exact amount of hops to do what I wanted. There wasn’t as much Warrior and that was suppose to be the bittering. As a compromise I moved some of the Fuggles from aroma stage to taste. By moving them earlier it should add a bit more bitterness, and hopefully balance. Will have to wait and see.
Once the boil started we re-hydrated the yeast. It’s the first time I’ve done this. It was pretty easy. The only problem is the water that was boiled so early on it cooled down too much. A quick zap in the microwave brought it back up to temperature. The yeast sat in the water while we dissolved the tea spoon of dry malt in half a glass of boiled water. Then waited half an hour before adding that in and gave it a mix.
I held off on adding the dry malt for a bit. Have been getting advice not to add all malt at the start of boils and wanted to try it out. As a result we didn’t get a hot break, it just came to a boil. Bittering hops went in at start, then taste hops at thirty minutes with the first 800 grams of dry malt a five minutes later. Another fifteen minutes later added in the last 400 grams of dry malt. Five mins after that the aroma hops. Then only five more mins before flame out.
Pot was transferred to an ice bath. Some ice cubes went directly into the wort, water previously boiled before frozen. A second bath for the pot. Then into the fermenter. Added a little more sparged grain liquid, that might not have been the best idea as I’m not sure if that could have lead to contamination. Too late now! The liquid malt only went in at this stage, note that it wasn’t part of the boil. Not sure if that will make much difference. Let me know what you think with a comment below.
The wort was still quite hot. That was even after adding about four litres of very cold water. Will need more ice if I’m going to do something this large and this method again. After a couple hours the temperature was down to something close to what I wanted. Yeast was pitched at about 25°C. I forgot to put the yeast nutrient in at the same time. So, went back an hour later and put in four heaped teaspoons and sealed back up.
60 min mash at 68°C
– 1.5 kg of Crystal 120
– 500 grams of Chocolate Malt 600
Boil wort from mash
add 8 grams of Warrior hops
add 14 grams of Fuggels hops
add 800 grams of light malt extract
add 400 grams of light malt extract
add 5 grams of Fuggels hops
– 1.7 kg of Amber liquid malt extract (Black Rock)
– water & ice to bring to 17 litres
Once at 25°C
add 7 grams of yeast, 5g Windsor & 2g kit yeast (previously re-hydrated)
add 4 heaped teaspoons of yeast nutrient
A bit of a strange brew. Some new techniques and processes. Some corrections from previous brews. Some ingredients just thrown together, like hops and yeast. The final gravity came in at 1.071 which is pretty good given the calculated was only 0.002 higher than that. If fermentation can take it down to 1.025 that will mean about 6.5% alcohol before bottling. And this one will be bulk primed.
Fingers crossed ay 🙂
It seems like it should turn out alright. You wont risk contamination etc adding the LME at the end but it may contribute a different taste to the intended recipe. Your guess is as good as mine when it comes to how it will affect it.
