Based on reading this thread, and advice from a brew buddy who swears by Bell's Two Hearted Ale (which I've never had sadly), I decided to make this my next brew.
Brew Day came, and I went to Home Brew Mart here in SD to get my ingredients. Wouldn't you know they were out of Vienna! So, had to improvise. Based on their recommendations, I ended up substituting Victory Malt for the Vienna. Yes, I know it's a darker malt. But I think it was the best choice for what my options were at the time.
I also adjusted the recipe upward to hit closer to 1.070, which seemed more likely to yield a 7% ABV beer to me, based on my experience. Of course, I had a bit hight efficiency than expected, and the boil resulted in a bit more volume loss than I'd planned. Goal was to end with 6 gal (enough for a keg, and to bottle condition some), and ended with 5.8 gal.
So, long story short 1.076 was the OG post boil. IBUs had been adjusted slightly upward to 57. I also First Wort Hopped 30% of the late hop addition, which hopefully will smooth it out a little.
Wort tasted awesome, and the old WLP001 is chugging away on it now. I suspect it'll be a great brew...but how close to Bell's is any ones guess.
Any thoughts on how different a beer I am looking at given the Victory substitution?
