I brewed what seems an excellent kit from HBC - 'The Madness' velvet stout.
Bottled it with regular table sugar (granulated sugar boiled in a little water for 10 mins).
So far after 19 days conditioning at 20°C the complex flavours are coming through. There is a bit of head and it is improving, but no small tight bubbles that would make a lasting head and lacing. In the meantime I have a Festival IPA conditioning for 14 days which is well carbonated on dextrose and lacing lasts for ages with the same hard brewing water.

How long should I leave this stout in warm temperatures before moving to colder spot in the garage?

Also what is it that makes a decent head?
It may be that my water, which is hard, just doesn't help head retention unless there's some special adjuncts in the recipe.

I need to move the Stout out of my conditioning cupboard to make way for a recently fermented Northern Brown Ale, so need to know if it's worth leaving the Stout to condition in the warm for longer?

Help appreciated.
 
19 days is plenty of time for the beer to carbonate, so now move it somewhere cool to condition. Carbonation (yeast eating priming sugar to produce the CO2 required) - fermenting temperature. Conditioning (the maturation of a carbonated brew) - cellar temperature.

That's the way I see it, anyhows! acheers.
 
Thanks. It is carbonating well and tastes pretty good so far (probably needs a couple more weeks in the bottle) but head retention could be much better for a stout.
 
Usually 2 weeks at house sort of temps 18-20C during the day will be fine to carbonate the bottles up. (Good tip is to bottle one in a PET bottle - plastic fizzy pop bottle to give you an idea of when it is carbonated).

This carbonation is Not the same as conditioning, of course. After 19 days it can go in the garage to actually condition and as it is a 5% + sort of a beer, you can leave it there for 3 months for it to get to its best.

As to what makes a decent head on a beer - all my glasses get washed in a dishwasher and there is almost no concept of a head retention, just a big fizz at the start of pouring into the glass.

Leaving your stout in the warm any longer achieves nothing once it is carbonated.
 
I chase the elusive head retention.

2 sachet kit has plenty head. All grain kit has poor head. I am wondering if it is related to the sugar used for bottling. Granulated vs. dextrose. Does anyone have any anecdotal evidence that dextrose is better?

It is chemically identical and any anecdotal evidence is basically of little actual relevance. Lighting a candle for the Fig Tree Fairy might work, as she has much influence in such matters as head retention.

On a more serious note, if you are concerned about having a load of bubbles and good "lacing", then you need a beer with a relatively high finishing gravity, good carbonation and a glass that is absolutely free of all cleaning products.
