I poured a 12oz bottle into a goblet. It was bottled on 8/23/13 and cost $2.50 ($0.21 per ounce).
Appearance: Beautiful red hue (as advertised); dark but translucent with
some carbonation visible. Pours to a small, white, frothy head which
laces and retains well.
Smell: Citrus, flowers, and piney hops altogether.
Taste: So it appears as though "Red IPAs" are a thing now. Though the
name derives from the color and isn’t just a hoppy version of an Irish
Red. I guess if anyone can pull off a derivative of the American IPA
style it’d be Sierra Nevada, and they’ve definitely done well with the
Flipside Red IPA. Surprisingly East Coast in character with plenty of
piney, resiny, dank hop bitterness. The malt base is present, but
subdued, imparting a slightly sweet, almost candy-like taste. The hops
are bright and citrusy up front, but earthy and dank on the back end. A
fine amount of bitterness, especially at the crest of the swig, but it’s
not too intense. This is what a standard IPA should drink like.
Residual bitterness on the tongue with just a hint of confectionery
sweetness. Overall, it’s a well-balanced and interesting beer.
Drinkability: The best IPAs to drink are the ones that have the greatest
sense of balance, so it’s no wonder that Sierra Nevada Flipside Red IPA
rates high on my drinkability scale. The mouthfeel is medium to full
bodied with consistent carbonation intensity. At 6.2% ABV it makes good
use of its weight as it’s plenty flavorful, but nothing obese.
