I'm a noob to home brewing and the site...
I had a pecan beer (OK a few of them) while working near Las Cruces, NM 5 months ago, I've been looking for a pecan beer ever since.
A local store was selling a "Home Brew Kit", makes 2 gallons. The enclosed HME was just a regular "light beer". Table sugar was added to the bottle for carbonation. That batch turned out better than I imagined, so I made a second.
The amount of table sugar I added to a bottle was about 6 grams of sugar. I found a pecan waffle syrup that had corn syrup, water, and natural pecan flavoring. 1 tablespoon of the syrup had 6 grams of sugars.
I experimented with using half the table sugar and 1/2 tablespoon of the syrup and a full tablespoon of syrup.
After the 2nd fermentation was complete, we tried them, both had a good head and carbonation.
The bottles with 1/2 & 1/2 , had almost no pecan flavor.
The bottles that had a full tablespoon of the syrup, had a definite pecan flavor but it was very mild and more prevalent when the beer had warmed a little.
The next batch will have bottles with 2, 2-1/2 and 3 tablespoon of syrup bottles, all with no table sugar.
I have no idea what to expect, but I'll know for sure in a month.
