I've tried a couple batches of root beer now, each 1.25 liters in size (plastic soda bottle). Each time it tastes alright, but it smells really bad. My friends say it's a yeasty smell, so I think there's an issue there. I have searched around on this forum in addition to using Google, but it seems like I'm doing things properly, hence deciding to post here.
Here are the steps I followed. I was wondering if any of them seem to be the cause:
1. Clean out containers and anything used to make the root beer using PBW and then sanitize things with Star San.
2. Heat the following until everything dissolves together:
- 3.75 cups water
- 1/4 cup white sugar
- 3/8 cup brown sugar
- 1/2 tbsp malto dextrin
- 1/4 tbsp root beer extract (I've tried both Zatarain's and McCormick's)
3. Once araound 85*F, add 0.068g yeast (I'm using "Red Star Active Dry Wine Yeast (Pasteur Champagne)", which was recommended by the local brew shop).
4. Fill bottle until there's a 1.25 inch gap at the top.
Note that I double this recipe when mixing things since it's for a smaller bottle than mine, so the 1.25 inch gap is still correct for me.
I let it sit for about 3.5 days before refrigerating it. It took that long for the bottle to be firm enough that I couldn't indent it by squeezing it.
I'm pretty sure the taste would be really good without the smell, it's just hard for me to drink with it present.
Sorry for such a long post... Anyway, I'm hoping you guys can help out. Thanks in advance!
