Deschutes Drop Top Amber is a fairly decent example for those who have had it.
Too bad, to me it;s the quintessential example of the style, but that's just my opinion. Maybe because it was the first version I ever tasted and it tainted by opinion.
Look and see if Bell's "Big porch ale" is available, it's pretty much the same beer repackaged to market the Grand Hotel on Mackinaw Island. It may be available in NY under that name.
If not I have a simple extract clone recipe for it I came up with years ago, that although it is a tad darker than the original, tastes spot on.
Drop Top is Widmer, but yes.. it's tasty. Deschutes has Green Lake Organic Ale, which is an amber, and Cindercone Red. Both are tasty beverages, but I still say that you don't need any other american ambers, so long as you can get Anderson Valley Boont Amber.
Is an American-ESB an actual style
