If you've ever followed a fruit wine recipe, you've probably come across an ingredient called pectolase.
It's often listed alongside wine yeast, yeast nutrient and Campden tablets, yet many beginners have no idea what it actually does.
As a result, it's one of the most commonly skipped ingredients in home winemaking.
Unfortunately, that decision can sometimes lead to disappointing results.
Cloudy wine, poor juice extraction and longer clearing times are all problems that pectolase is designed to help prevent.
The good news is that it's easy to use, inexpensive and can make a noticeable difference to many fruit wine recipes.
In this guide we'll explain what pectolase is, how it works and whether you really need it when making wine at home.
What Is Pectolase?
Pectolase, sometimes called pectic enzyme, is a winemaking additive used to break down pectin found naturally in fruit.
Pectin is a complex carbohydrate that helps give fruit its structure.
It's particularly abundant in fruits such as:
- Apples
- Pears
- Plums
- Peaches
- Blackberries
- Strawberries
- Gooseberries
While pectin is useful in jam making, it can create problems in winemaking.
Excess pectin can trap particles in suspension, making it difficult for wine to clear properly.
This is where pectolase comes in.
By breaking down the pectin, the enzyme helps release more juice, improve flavour extraction and encourage a clearer finished wine.
Why Do Fruit Wines Go Cloudy?
One of the biggest frustrations for new winemakers is waiting months for a wine to clear.
Sometimes the wine remains stubbornly hazy despite repeated racking and plenty of patience.
In many cases, pectin is the culprit.
When fruit is crushed, chopped or heated, pectin is released into the must.
If too much remains in suspension, it can create what winemakers refer to as a pectin haze.
Unlike yeast sediment, pectin haze often doesn't settle out naturally.
This is why many fruit wine recipes recommend adding pectolase at the very beginning of the process.
Preventing the problem is usually much easier than trying to fix it later.
How Does Pectolase Work?
Pectolase contains enzymes that break down pectin molecules into smaller components.
This process helps release juice trapped within the fruit while reducing the amount of pectin left suspended in the wine.
The result is often:
- Better juice extraction
- Improved flavour extraction
- More efficient fermentation
- Faster clearing
- Brighter finished wine
For many fruit wine recipes, it's one of the simplest additions you can make to improve the final result.
That's why experienced country winemakers rarely leave it out when working with pectin-rich fruits.
Which Wines Benefit Most From Pectolase?
Not every wine recipe requires pectolase, but many fruit wines can benefit significantly from its use.
Generally speaking, the more pectin a fruit contains, the more useful pectolase becomes.
This is why you'll find it recommended in many traditional country wine recipes.
Strawberry Wine
Strawberries contain enough pectin to cause persistent haze problems if pectolase is omitted.
Adding pectolase at the start of fermentation helps improve juice extraction and encourages a clearer finished wine.
It's one of the reasons pectolase appears in our strawberry wine recipe.
Peach Wine
Peaches are naturally rich in pectin.
Without pectolase, peach wines can take considerably longer to clear and may remain hazy for months.
Most experienced winemakers would consider pectolase essential when making peach wine.
Blackberry Wine
Blackberries contain both pectin and plenty of colour compounds that winemakers want to extract efficiently.
Pectolase can help improve both juice yield and flavour extraction during fermentation. See our blackberry wine recipe for a full step-by-step guide.
Apple and Cider-Based Wines
Apples are another fruit naturally high in pectin.
This is one reason pectolase is commonly used when making apple wine, cider and other orchard fruit wines.
Gooseberry and Plum Wines
Many traditional British country wines benefit from pectolase additions.
Gooseberries and plums can both produce excellent wines, but pectin haze can become an issue if the enzyme is omitted. Browse our country wine recipes for more inspiration.
When Should You Add Pectolase?
For most fruit wine recipes, pectolase is added before fermentation begins.
This allows the enzyme to start breaking down pectin while the fruit is still releasing juice and flavour.
A typical process looks like this:
- Prepare the fruit.
- Add water and other ingredients.
- Add Campden tablet if required.
- Wait according to the recipe instructions.
- Add pectolase.
- Add yeast nutrient and wine yeast.
Following this sequence helps ensure the enzyme has the opportunity to work effectively before active fermentation begins.
Always follow the manufacturer's instructions for dosage and timing.
What Happens If You Forget to Add Pectolase?
The good news is that forgetting pectolase doesn't automatically ruin a batch of wine.
Fermentation will still occur and the wine may still taste excellent.
However, you may experience:
- Slower clearing
- Persistent haze
- Reduced juice extraction
- Longer maturation times
Some winemakers only realise they forgot pectolase several weeks later when the wine stubbornly refuses to clear.
At that point, additional pectolase can sometimes help, although results are often better when it's added at the start of the process.
Can You Add Too Much Pectolase?
Pectolase is generally very forgiving when used correctly.
Most winemakers follow the dosage recommendations supplied by the manufacturer and experience no issues.
Adding significantly more than recommended is unlikely to provide additional benefits and simply increases cost.
As with most winemaking additives, following the instructions is usually the best approach.
Frequently Asked Questions
Can I make fruit wine without pectolase?
Yes.
Many people successfully make fruit wine without using pectolase at all.
However, you may experience slower clearing, lower juice extraction and a greater risk of pectin haze.
For fruits such as strawberries, peaches, apples and plums, most winemakers find that using pectolase produces more reliable results.
Does pectolase affect flavour?
Not directly.
Pectolase is used to break down pectin rather than alter the flavour of the wine.
However, because it can improve juice and flavour extraction from the fruit, many winemakers feel it helps produce a fuller fruit character in the finished wine.
Is pectolase the same as yeast nutrient?
No.
These are two completely different products.
Pectolase breaks down pectin in fruit, while yeast nutrient provides the nutrients needed for healthy fermentation.
Many fruit wine recipes use both because they perform separate jobs.
Can pectolase clear a cloudy wine?
Sometimes.
If the cloudiness is caused by pectin haze, adding pectolase may help improve clarity.
However, if the haze is caused by yeast, protein or other particles, different finings or clearing methods may be required. Use a hydrometer to confirm fermentation is complete before investigating clearing issues.
Does grape wine need pectolase?
Most traditional grape wine recipes don't require it.
Pectolase is most commonly used in country wines and fruit wines where pectin levels are significantly higher.
How long does pectolase take to work?
Pectolase begins breaking down pectin relatively quickly, although the visible effects may take several days or weeks to become apparent.
For best results, it should normally be added before fermentation begins.
Final Thoughts
Pectolase may not be the most exciting ingredient in the winemaking cupboard, but it can make a significant difference to many fruit wine recipes.
By helping break down pectin, it improves juice extraction, supports flavour development and reduces the risk of stubborn haze problems later on.
For wines made from strawberries, peaches, apples, blackberries, plums and other pectin-rich fruits, it's one of the simplest ways to improve your chances of producing a bright, clear finished wine.
While it's possible to make fruit wine without pectolase, most experienced country winemakers consider it a worthwhile addition.
If you're planning your next batch of strawberry wine, blackberry wine or another seasonal fruit wine, adding pectolase is a small step that can save a lot of waiting later.
