Wow full on this post...let's step through it
Was wondering were the best and cheapest place to buy an ageing barrel for the fine scotch whisky recipe.
Most scotches are aged in pre used ex sherry (sharper) or bourbon (wider more flat tasting if you like) barrels . A new one is going to need seasoning, charring to your preference and ... time.
Might want to consider using timber strips some result.. well almost and far cheaper and easier.
I use strips not chips it's about surface area, end grain exposure and taste... yes you can over oak a whisky.... chips can dump plenty of colour and flavour quickly hence the reason use strips it's much slower and you got time to catch it i.e. remove strips to suit your taste preference.
Rough rule for mine... 2 strips per 5lt in glass for first months test/taste... re check each month remove 1 timber strip for long term.
The timber is the key and takes time to understand don't forget 80% of flavour is coming from timbering/ageing. You need to taste and get comfortable with what you like.
I personally only leave the mid toasted for long term ...char for me is a colour initial kick and that it...unless it's a Rye and I know it going to take 1 - 2 years.
Next question is for a 25l batch how much would I be easier expecting in my potstill of alcohol. Just a guestamit.
From a 25lt run, sprit run i.e watered down pre stripped i'd be looking for 6 lt plus as a roughy hard to guess depends on cuts/ still and to be honest I can't recall perfectly been a while since I did a pot still second spirit run.
