Brew Enhancer vs Plain Sugar — What Should You Add to Your Home Brew Kit?

Every home brew beer kit you'll ever buy says the same thing on the instructions: add 1kg of brewing sugar or enhancer. Simple enough — except when you look at the options available, there are suddenly four or five different products to choose from, and no one really explains what the difference is or which one you should use. This guide answers that question properly.

Why Do Beer Kits Need Extra Sugar?

Home brew beer kits contain concentrated malt extract — enough to give you colour, flavour, and the character of the beer, but not quite enough fermentable sugar to hit the right original gravity for a full 23-litre batch. The extra kilo of sugar or enhancer tops up the fermentable content so you end up with beer at the right strength, typically 3.5–5% ABV.

The problem is that what you add has a significant impact on the finished result — not just strength, but body, head retention, mouthfeel, and flavour. White table sugar works, but it's not ideal. Here's why.

Option 1: White Granulated Sugar

Yes, plain household white sugar (sucrose) does work in a beer kit. Yeast can ferment it, and it will hit your target gravity. But there's a catch: sucrose ferments out very cleanly, leaving no body, no malt character, and noticeably thin mouthfeel. Many brewers describe this as a "cidery" note — a slightly sharp, almost winey edge that isn't what you want in a malt-based beer.

Verdict: Not recommended if you want the best results from your kit. Use it only if it's genuinely the only thing you have.

Option 2: Brewing Dextrose (Glucose)

Dextrose (also called glucose or brewing sugar) is a monosaccharide — yeast can ferment it directly without needing to break it down first. It ferments cleaner than sucrose and produces less of that cidery off-note. It's the most basic upgrade from white sugar and the minimum we'd recommend.

Our Brewing & Winemaking Sugar at BrewCo UK is pure dextrose, specifically intended for home brewing use.

Verdict: Good baseline. Cleaner than white sugar, still ferments out leaving minimal body.

Option 3: Coopers Brew Enhancers (1, 2 and 3)

This is where things get genuinely interesting. Coopers produce three brew enhancers, each one a blend of dextrose with increasing amounts of malt-based ingredients:

• Brew Enhancer 1 (Light) — Dextrose plus a small amount of maltodextrin. Maltodextrin is a non-fermentable complex carbohydrate that adds body and mouthfeel without adding sweetness or affecting ABV. Better than plain dextrose, especially for lighter beer styles like lager and pale ale.
• Brew Enhancer 2 — Dextrose, maltodextrin, and Light Dry Malt. The addition of spray malt adds genuine malt character, improved head retention, and a fuller, rounder body. This is the most popular all-rounder and our recommendation for most kits.
• Brew Enhancer 3 — Higher proportion of Light Dry Malt, less dextrose. Produces the fullest body and most malt-forward character of the three. Best suited to ales, bitters, and stouts rather than lagers or lighter styles.

Verdict: Brew Enhancer 2 is our top pick for most kits. It's a significant upgrade over plain sugar with minimal extra cost.

Option 4: Spraymalt (Dry Malt Extract)

Spraymalt is powdered malt extract — the purest malt-based sugar addition you can make to a kit. It comes in Light, Medium and Dark varieties, each one adding different colour and flavour characteristics to your beer. Using 500g–1kg of spraymalt in place of sugar produces noticeably fuller, more complex beer with excellent head retention and a genuine malt backbone.

The downside is cost — spraymalt is more expensive than dextrose or brew enhancers — and you need to match the colour to your kit (use Light spraymalt with a pale ale or lager, Medium with a bitter or amber ale, Dark with a stout or porter).

Browse our Spraymalt & Enhancers range at BrewCo UK — we stock Light, Medium and Dark in 500g packs.

Verdict: Best possible result, especially for premium kits. Worth the extra cost if you want the best beer your kit can produce.

Quick Reference Guide

Addition	Body	Head	Malt Flavour	Best For
White sugar	Poor	Poor	None	Last resort only
Dextrose	Low	Low	None	Budget brews
Brew Enhancer 1	Medium	Medium	Slight	Lagers, pale ales
Brew Enhancer 2	Good	Good	Yes	Most kits — best all-rounder
Brew Enhancer 3	Very good	Very good	Strong	Ales, bitters, stouts
Spraymalt	Excellent	Excellent	Very strong	Premium kits, best results

Our Recommendation

For most home brewers using a standard kit: use Brew Enhancer 2. It's the single biggest improvement you can make to a kit brew for minimal extra cost, and the difference in the finished pint is immediately noticeable — better head, fuller body, rounder malt character.

If you're using a premium kit like Muntons Connoisseurs, Woodforde's, or St Peters, go the extra step and use Light or Medium Spraymalt — it matches the quality of the kit and produces beer you'll be genuinely proud of.
