Fluffernutter Sammie Stout Update

Update 5/24/2016: An unexpected little run of cooler temperatures had me worried that the beer was not fermenting. I know it did for a couple of days, albeit a bit slowly…never really started “chugging”, but going. Then the cool weather, and my little fermentation chamber is outside. It is only able to cool, not warm, so this could be a problem. Since the overnight low last night was going into the mid to lower 50’s, I decided to bring the carboy inside.

I took a sample and did a temperature and hydrometer reading. The temp was 62.5, so it wasn’t terrible…a little under optimum range, but should not be low enough to have caused any harm. The hydrometer has the specific gravity at 1.030, so it definitely was fermenting. That’s good! Adjusting for the lactose, I think it will likely only go to 1.028 or so.

The flavor of the sample has my hopes up! The color may be a tad light, but it’s a little darker than the sample shows, because of the camera flash and the particles had not settled out yet. I could definitely taste the peanut flavor, especially in the finish. Nice malty sweetness. After the sample chilled overnight, the peanut flavor is more muted. With that and the consensus from others that the peanut flavor will start fading after a couple of months in the bottles, I do plan to add more peanut powder to secondary via boiling it with water and cooling it…probably a gallon and then racking onto it and the vanilla beans. I’m going to skip the marshmallow Fluff in secondary and rely on the vanilla for that flavor, so I’m not adding much more fermentable sugars. I may try adding some to the boil in a future batch, but not this time. I have a feeling that this beer’s flavor will improve as it loses some of its chill, after pouring.

The temperature on the carboy strip thermometer reads around 66-68F, so I’ll be putting it back in the fermentation chamber later today.

Brew Day: Fluffernutter Sammie Stout

Set up to brew.

Set up to brew.

 

Finally! For the first time in 7 months, I brewed some beer! I created this recipe months ago and tweaked it some, but just didn’t want to brew again until I was able to control my fermentation temperatures. I have had ongoing issues with over-carbonation and I have had some off-flavors, particularly with darker beers…some are metallic or just very one dimensional. I have addressed everything I can, except fermentation temperature and yeast selection. For this sweet stout, I decided to go with Wyeast 1968. Optimal temperature range is around 64 to 70F. So, instead of my normal household room temperature of around 72F, with wort temps reaching 75 to 78, I now have a small chest freezer with controls to regulate the temperature. I have it set at 63-64F. I’m hoping this will at least help the flavor of the beer. If it helps with the carbonation issue, too, then that would be awesome!

I did have to make some minor changes based on homebrew shop ingredients availability…nothing major. Brew day went very smoothly, except for mash temperature climbing to 160F, instead of 155F. With about 25 minutes left, I removed the insulation/lid and started stirring to lower the temperature. With 10 minutes left, it was down to 156-157.

My understanding is that the effect would be less fermentable sugars and possibly a little sweeter finish. I also added lactose with 10 minutes left in the boil. The end of the boil was fine, except the OG was high. I have a feeling that the lactose is not figured into the refractometer/hydrometer readings, because otherwise, it looks fine.

The boil is done.

As a result of being able to drop the temperature to 71-72F, pitch the yeast and drop the carboy in a 64F fermentation chamber, the “take-off” for the yeast was barely noticeable 20 hours later. There was just a ring of bubbles around the top inside of the carboy. Now, at about 26 hours, there is audible bubbling and more visible signs of fermentation.

My concerns, at this point, are whether or not I added enough peanut powder to be noticeable in the final product, and if the vanilla planned for secondary will give the marshmallow flavor. A couple little sips of the wort towards the end of the boil did not really convince me on the peanut powder…and what IS marshmallow flavor? Marshmallows are basically corn syrup, sugar, gelatin, and vanilla. I’ll investigate some more and see if peanut powder can be effectively added during primary or secondary fermentation, as well as exploring the marshmallow flavor a bit more. If I make changes, I will definitely update the recipe. For tonight, it’s reading, while the fermentation builds.
