Most of you probably don’t know this, but there are many scientific discoveries that were made by brewers. In fact, it was a brewery in London during the sewage problems of the 1800s that provided insight into the bacteria problems in the water. The people at the brewery were not getting sick because they only drank beer, which had undergone a boiling process. Those around the brewery were getting sick from the unsanitary water that was plagued by rotten sewage. But enough about that.
What is a stout beer? Stouts are dark, sometimes bitter beers that are brewed with roasted barley and malt. The barley is often roasted to the point of charring. This provides a “burnt” type of flavor that can often taste like coffee or chocolate. These beers can be all over the map in terms of hoppy-ness. But the main character of a stout beer in the roasted flavor.
An oatmeal stout is a variant of a stout beer that is brewed with steeped oatmeal added to the steeping grains. The addition of the oatmeal gives this variant a sweeter, smoother finish. Also, these have a more mellow character than a standard stout. The roasted character, however, remains in the beer. Some popular oatmeal stouts include Samuel Smith’s Oatmeal Stout and Young’s Oatmeal Stout.
My Beer: Newton’s Oatmeal Stout
Way back on September 11th, in honor of our awesome country, I brewed beer. It was my first time brewing a beer while using the steeping grains. Basically the steeping grains add about 30 minutes to the brewing process. You put a bunch of crushed grains like barley and malt into a sack and soak it in hot water for about 20-30 minutes. Then this becomes the base liquid for the boiling wort.
After you’ve steeped the grains, which is rather like steeping a tea pack in hot water, though on a much grander scale, then you can begin to brew the beer. The kits I have used have said to bring a gallon of water up to 170 degrees and use it to rinse the grains. So I simply pour the gallon over the grain sack and catch the water in the boiling kettle.
The wort boils for about 45 minutes, during which time the hops are added. After 45 minutes you’re basically done. You bring the beer down to about 115 degrees and add in enough water to bring it to about 5 gallons. Next you pitch the yeast, which is a fancy way to say you add yeast to the liquid. Then seal it up with an airlock and you’re good to go!
The original or starting gravity of my stout was 1.047. This isn’t a very high gravity, but stout beers aren’t known for being high gravity beers.
After a week in the fermenter I transferred the beer to a glass carboy. I let it ferment and age in the carboy for about three weeks and this past Sunday I bottled it.
Bottling is the worst part of the process. I don’t buy bottles, so I have to de-label them, which is a big pain. Then you’ve got to make sure your 45-50 bottles are clean, so I run them through the dishwasher without detergent. After that I sanitize them using One-Step. In the meantime I transfer the beer back to the plastic fermenter, dissolve bottling sugar, add the dissolved mixture to the beer, and then I proceed to bottle 10 at a time and cap them.
For this batch I ended up with 46 bottles, one of which will remain on my shelf for all time. Doing a little math, if an average 6-pack costs $8.50, which seems on par with my FLBS (Favorite Local Beer Store), then 45 bottles (7.5 6-packs) would cost about $64. The beer brewing kit itself cost about $42. So I am saving $22! That’s a considerable amount. The downside is that I have 7.5 6-packs of the same beer. Is that $22 worth having so much of the same beer? (It is worth it if you can bring it to game nights and drink other people’s beer!)
My Newton’s Oatmeal Stout had a final gravity of 1.015. This means that the beer has an ABV (Alcohol by volume) of 4.2%. Therefore I should be able to slam a bunch of these bad boys and feel little effect.
I like to name all of my beers after Renaissance men. In my opinion Renaissance men are not necessarily from the Renaissance. Rather, these are people who happen to be experts or masters in many trades. Sir Isaac Newton was definitely a Renaissance man.
I could have chosen a pudgy character who more closely fit the bill of being “stout.” However, Newton seemed to fit the bill of being “stout” due to his contributions to science and his place in history. I suppose I could have saved Newton in case I ever brewed an apple ale, but I don’t think I’ll ever brew an apple ale. So Newton joins my Renaissance fleet that already includes Leon Battista Alberti (Amber Ale) and Benjamin Franklin (Honey Ale).
In a couple of weeks a new Renaissance man will join the team behind the guise of a Scotch Ale. Unfortunately William Wallace is not technically a Renaissance man, so I’ll have to choose a different Scot as the namesake for the beer.
If anyone has questions about brewing or beer styles or anything having to do with zymurgy, please let me know!
