The Belgian Homebrew

Today’s brew has been a few weeks in the planning. In 2017, I really want to focus on the home brewing style of Belgian ales and today is the start of that, albeit a slightly experimental approach. The aim was to create a standard ‘sessionable’ Ale with a focus on a Belgian noble hop style aroma. 2016 will be the last year that I will subject myself to substandard supermarket ales, the money saved will go on more homebrew supplies and a third stainless steel fermenter. In this brew, I wanted to start with a standard beer base without too much malt influence to influence those noble hops too much. Here goes!

2.0kg Pale Ale Malt

2.0kg Maris Otter Malt

400g Wheat Malt

250g Rolled Oats

Fermentis Safbrew S-33 Yeast

30g Apollo 19.5%A @ 60 mins

50g Strisselspalt Dry Hop 2.3%A (5 days)
 Target 1042

One thing that I am slowly starting to appreciate in my current setup, is the grain mass vs efficency. Its only taken 2 bloody years to realise what i’m doing wrong! I’m guessing that the surface area of grain to water and relative solubility/absorption is limited by the size of the mash tun. Using a lower grain bill, I pretty much smashed my target SG of 1042 by achieving 1041.

Today was back to basics. Minimal hops, grain and messing about. Maris Otter was used as 50% of the base to add a bit of biscuitiness and flavour with 50% low colour simple Irish pale ale grain to finish off the core. 250g of Oats was also added to give the wort a little bit of body and mouthfeel to avoid a watery finish. I finished off with a chunk of wheat malt to add a little sweetness, head retention and hopefully a flash of cloudiness.

The strike water was deployed at a respectful 77°C, and after preheating the mashtun, the water landed and the cold grain was added and stirred in. The mash water was now 66°C. The lid went on and ten minutes later I took a PH reading of 5.5% which was just within tolerance. An hour later, filtered drain to the boiling pan, a sparge and a 30 min additional mash meant the beer was about ready for boil.

Collecting first runnings from the mashtun

Due to it being a cold day of just around 4°C, the boil point took a little bit longer than usual, then adding the Apollo hops at 60 minutes in a large steel tea strainer. An uneventful boil and cool down to 22°C then allowed the pitching of the yeast. I usually do this as the cool wort is gravity tapped into the steel fermenter in order to get as much foam and oxygenation as possible.

In discussion on the yeast, I’m using a variety that I’ve never used before. It appears to be a Marmite yeast. Love it or hate it! I didn’t want to use a funktastic T-58 variety nor an Abbey yeast as I wanted the Strisselspalt flavour and aromas to shine through. This is supposedly a standard British ale variety of yeast with little flavour contributions or esters at a low temperature. Fingers crossed!

After primary fermentation, a later addition of 50g of Strisselspalt hop leaf was added in a stainless steel mesh hop spider, weighted with stainless ball bearings. This sat in the fermenter for 5 days.

Every home brewer knows how important the bottle conditioning process is. Every homebrewer also has a degree of impatience. This, for me, is demonstrated during the secondary fermentation stage, where there is always a temptation to see if the brew has carbonated properly. The opportunity to sample a ‘green’ beer is also too good to pass.

This beer, after 5 days tasted pretty dreadful. This s-33 Safbrewyeast variety is one that I’ve never tried before, with varied reviews online and across the forums. The yeast presence was overbearing and the body was young tasting and sweet. I was considering dumping the lot.

After 4 weeks, thankfully, the beer has matured into a classic tasting beer. The closest resembling commercial Ale would be ‘tasty’ Kronemburg. Decapping the bottle gives a faint whiff of white wine which dissepates instantly to gives a classic grassy noble hop aroma. The body is full (surprising for a 4.0% ale) and has a pleasantly dry aftertaste without the ester intensity of the t-58. The beer is best served at fridge temperature as opposed to room temp.
