A local distillery here was buying their single malt washes from a local brewery during their start up, and as they were eventually able to mash their own onsite, the brewery was left with about 20 cubes of single malt washes which they have been selling to me for $20 each. So far I've bought 8 22l cubes in total.
I distilled a 44l wash 8 weeks ago and I've been sampling it ever since but it tastes nothing at all like scotch. It's overly sweet to the point that I can't drink too much of it.
It was made using 100% pilsiner malt with a final gravity of 1.072 and I fermented it using safspirit American whiskey yeast.
I've been ageing it in mason jars at 62.5% with 12g med charred American oak/litre and I can't say that it's improved at all during the last 2 months.
I've read a lot of comments here regarding people's opinions on boiling whisky wort and the claims that it will carry over unwanted sweetness, however some people tend to disagree. As these were cubed, they have been boiled so Im wondering if that's what's caused this unwanted sweetness to occur.
I also read in a distilling book that when aiming for a scotch-style whisky, at least a small amount of peated malt is "necessary for a crucial chemical reaction" even if the distiller dislikes peated whiskies.
I'm thinking that with the next cube I'll mix it 50/50 with 20l heavy peat and see what happens but in the meantime I'd really like to hear some of your opinions on this.
