what does dopplebock mean?

From Beer Advocate:

"Description:

Double Bocks or Doppelbocks are huge beers with enough malt packed in them to consider them a meal in its self. Generally having a very full-bodied flavor and darker than other bocks with a higher level of alcohol also. The range in color from dark amber to nearly black. Dark versions may have slight chocolate or roasted characters."

It is a fuller bodies and higher alcohol content lager. Ayinger Celebrator Doppelbock is considered by most to be the best amongst the style. One of... if not the best lager I've ever had. I love the ruby color when held up to the light.

EDIT:

sorry... figured I should also explain what a bock is.

"Description:

The origins of Bock beer are quite uncharted. Back in medieval days German monasteries would brew a strong beer for sustenance during their Lenten fasts. Some believe the name Bock came from the shortening of Einbeck thus "beck" to "bock." Others believe it is more of a pagan or old world influence that the beer was only to be brewed during the sign of the Capricorn goat, hence the goat being associated with Bock beers. Basically, this beer was a symbol of better times to come and moving away from winter.

As for the beer itself in modern day, it is a bottom fermenting lager that generally takes extra months of lagering (cold storage) to smooth out such a strong brew. Bock beer in general is stronger than your typical lager, more of a robust malt character with a dark amber to brown hue. Hop bitterness can be assertive enough to balance though must not get in the way of the malt flavor, most are only lightly hopped."

Doppelbock or double bock is a Bavarian specialty beer that was first brewed by the monks of St. Francis of Paula. Alcohol content ranges from 6% to over 10% by volume. Historic versions had lower alcohol content and higher sweetness, and was considered "liquid bread" by the monks. Most versions are dark colored, but pale versions do exist. The color ranges from deep gold to dark brown in color, with a large, creamy, persistent head ranging from white for pale versions to off-white for darker versions, although doppelbocks with higher alcohol content may not display good head retention. It has a very strong malty aroma, with some toasty aromas. Some alcohol aroma may be present, and darker versions may have a chocolate-like or fruity aroma. The flavor is very rich and malty, with toasty flavors and noticeable alcoholic strength. Most versions are fairly sweet, due to little or no hop flavor. Paler versions may have a drier finish.

The Minim monks who originally brewed Doppelbock named their beer 'Salvator', which today is trademarked by Paulaner. In homage to the original, it is traditional for breweries to give their Doppelbocks names that end in '-ator.'"

I hope that helps!

it's a type of beerr.
