Sherry-like Flavour.

[Little Rock Brewing]

Tried a bottle of an Affligem Blonde clone I made a while back (I'd have to check the date) but was disappointed that it was very sherry tasting and the complete lack of carbonation meant it looked like sherry too!
Any pointers as to what may have happened?

Oxidation is the problem gives a sherry/cardboard taste with a brown colour to it which is why it will look like sherry. Looks like the top has not sealed properly and allowed oxygen in hence no carbing too

The sherry like taste is most likely due to oxidation and perhaps in part to the yeast used.
Lack of carbonation would be due to leaky storage in bottles / keg or due to no priming sugar being added.

Darn it, I thought my oxidation days were over.
This is the first time I used 330ml Peroni bottles. I wonder if they are somehow different to my usual bottles.

If it was a bad seal then it's unlikely that all of the bottles are badly sealed. Try another one and if it's the same them look elsewhere for a reason.

I'll crack a couple more later. It's a bit early for the 7% beers!

It's never too early for a bit of quality control.

Update. Had 2 last night and both grim. Today opened one that was in a 200ml Coke bottle, used for viewing purposes. Absolutely great, carbonated and tastes lovely. I've gone deeper into the 2 crates of Peroni filled bottles to see if they are better. Fingers crossed.

Well at least that's good news that the whole batch isn't spoilt. Hopefully some of the peroni bottles are ok, but it'd probably be best to not use them again. I'm not sure how they would be different, but not worth risking another brew.

Throw the Peroni bottles if you think that is the issue. Still points to poor seal and oxidisation IMO

Obviously test each bottle first though

Not a solution, just an observation:

It's a tragic throw-back to 1960-70s that we still think of sherry flavour as oxidised. Sherry isn't oxidised as such (unless you are unluck), the flavour is usually the result of another yeast (and it did require a bit of oxygen late on) ... but the abominable British "sherry" often was just simply oxidised.
