Re: Best "Basic Balvenie"
I appear to be in the marginal minority here, as I've tended to prefer the Double Wood over the Founders Reserve. However, I'll qualify this personal assessment by stating that the FR has, over the course of many years, seemed the more consistent of these two. I have not, as yet, had the opportunity to taste the Signature.
The DW, when at its best, has always lured me with its orange and Sherry-infused flavour as well as its textural richness. (In this regard, I suppose I fall into the same camp as the late and sorely missed Michael Jackson.) The whisky has also struck me as highlighting whatever minimal peat component (admittedly very subtle) is present in the distillate to better effect than the FR.
Neither the FR nor the DW hold a candle to the 15YO Single Barrel in my books, though.
