No activity in wheat beer

[Chris_1984]

Some 12+ hours after making a 1 gallon batch of wheat beer, there is no/little activity that I can see happening in the demijohn.
This is my frist time making wheat beer - does it take a bit longer? Is it the ingredients used?

The ingredient list:

12oz wheat malt
4oz maris otter
8oz Holland & Barrett Malt Extract
Goldings hop teabag
half satchet Muntons Active Brewing Yeast

If anyone has any ideas i'd be most grateful (before I get worried & chuck it)

12 hours is not long - Don't worry for at least another day

How do you know it's not fermenting? Have you not seen bubbles/activity on the surface?

Assuming that:
- the malts were correctly modified and selected,
- mashing correctly executed (conversion successfully made),
- sufficient yeast count was correcty prepared and pitched,

...otherwise there is no sense in worrying, for now.

Wait another day (or two) and see what happens.

In the meantime could you please verfify the type of wheat you have employed?

I'm also assuming that the demijohn, which is protected by airlock, has a volume of circa 5.5 gallons hence the volume of the of the fermentable content in the fermentor is < 20%.
To occupy nearly > 4 gallons of volume you would need a significant amount of CO2 before observing any impressive airlock activity.

Hope this helps.
