How much Malt Extract?

[MrBarrySir]

Hi all, I have 22 litres of an english IPA in the fermentation bin after 2 days. The OG was however 1.050 instead of 1.060, i'm thinking this was because I added too much water during the boil stage. I've ordered some dried malt extract to hopefully bring it up to 1.060, how many grams roughly should I need to add?

Thanks

Use this http://www.brewersfriend.com/homebrew/recipe/calculator/ to adjust from what you put in originally to what you now require. I find it is quite accurate.
However, your problem may be getting the DME to dissolve in your brew, unless you can persuade it to dissolve in a minimal amount of water before you add it. You may be better off using liquid ME, assuming you want to avoid using sugar.

Cheers for that link. I was planning to dissolve it in water before I added it, I've never used it before though - is it a nightmare to dissolve?

Not quite nightmare just very difficult. It clumps up at the first sign of moisture. Your first option is to try to get it to dissolve in boiling water, then cool it to fermentation temperature and then chuck it in. Otherwise just chuck it in as it is and hope the greedy yeasties can gnaw their way through it. Either way don't expose your brew to the open for too long or you may contaminate it.

Bit confused with how to work backwards with the calculator - am I right in saying i'd need ~0.5kg to bring it up 0.010 given the above info?

For 22 liters??? Hmmn my gut would say almost 1 kg

Use the calculator to estimate your SG using your initial quantities and volume (22l ?) . This should give approx 1.050.
Then put into the calculator increasing amounts of DME to bring up the SG to 1.060. If you intend to use water to dissolve the DME you need to increase the brew volume to take this into account. When the new SG reaches 1.060 the estimated weight of DME the calculator shows is what you need to put in, assuming you did not use any at the start.
If you are completely stumped, then tell us what you used at the start , and someone on here will work it out for you assuming you still intend to use the DME.

My fermentables are 5.8kg of pale malt and 145g crystal malt. I have 22l in the bin. The calculator is saying I should be starting at 1.066 so should I just add virtual malt extract to bring it up by 0.010? If so it's saying .7kg.

Using the calculator the OG is elevated by approx 0.010 either adding 0.7kg DME to your original fermentables or to a fermentable bill of 4.5kg pale/0.145kg crystal (which the calculator gives as an OG of 1.050), so if you are using DME I would go with that. If you use 0.75kg liquid malt instead the result is the same.
These numbers suggest that your extract efficiency is not as good as the calculator but I can't help there because I don't do AG.
Hope this helps

That's great, thanks for your help with this, I'll go with the dme, it was delivered this morning.
