On the subject of Essencia Bourbon Chunks.
The first time I used this branded product, in 2010, I was blown away by the results. It did exactly what it said on the tin ( plastic bag, actually!) I was tasting the product off these chunks against Maker's Mark and Four Roses. There was no contest, the product off the Bourbon Chunks was far superior.

Unfortunately the results from the next two 500g bags were nothing like my first experience. Indeed, I posted in this thread about past poor results.
I recently returned home from a trip to the UK where, undeterred, I had bought another 500g bag of the same "Bourbon Chunks" from my suppliers (lovely people). I was determined to give Essencia another chance and get a good result to prove that the past problems were but a hiccup. (I really wanted to replicate the result from the first batch it really was that good!)
After the initial 7 days, then 10 days, my lovely clean, filtered, spirit has a lovely colour but tastes like crap - I'm seriously considering chucking it back in the still.
(lest anyone suggest there might be a problem with the base spirit - I had tasted it before using on the offending timber, it was nectar!)
I now believe the glorious 'Bourbon Chunks' I got, on that first occasion, were probably part of a barrel from Booker Noe's private stock at the Jim Beam Distillery because every bag I've bought since has been absolute rubbish. The chunks I've had since that first batch taste like they might have come from a disused railway sleeper from somewhere near Kentucky.
For illustration purposes, Essencia's instructions for using their Bourbon Chunks are:
"For the best Bourbon available to the home brewer :-
• 500g Essencia Bourbon Chunks
• 2.5 litres alcohol
• Soak for 7 days then filter off. (Produces 2 x 1125ml bottles of excellent Bourbon)
Add a further 2.30 litres of alcohol to the used Bourbon Chunks and leave to soak for 19 days.
Filter off to produce 2 x 1125ml bottles of good Bourbon.
Add a further 2.30 litres of alcohol to the used Bourbon Chunks and leave to soak for 5–6 weeks to produce oaked spirit. Filter off, add 1 x bottle of Essencia Bourbon essence to this alcohol to make 2 x 1125ml bottles." End Quote
I am also firing off a salvo of rockets to the Maguire brothers at Essencia in New Zealand because I'm now satisfied, following my extensive testing, that the wood supplied as "Bourbon Chunks" under their name is completely lacking quality of any kind and it's provenance is now in question.
At this point I believe I could extract more and better flavour from lollypop sticks.
I will report back if I manage to get any useful information to pass on.
